PrE | Page 2 of 62 | March 2009 Preliminary Technical Data GENERAL DESCRIPTION The ADSP-BF512/BF514/BF516/BF518(F) processors are members of the Blackfin family of products, incorporating the Analog Devices/Intel Micro Signal Architecture (MSA). Blackfin processors combine a dual-MAC state-of-the-art signal processing engine, the advantages of a clean, orthogonal RISClike microprocessor instruction set, and single-instruction, multiple-data (SIMD) multimedia capabilities into a single instruction-set architecture. The processors are completely code compatible with other Blackfin processors. Table 1. Processor Comparison ADSP-BF512F ADSP-BF514F ADSP-BF516F ADSP-BF518F ADSP-BF512 ADSP-BF514 ADSP-BF516 ADSP-BF518 ADSP-BF512/BF514/BF516/BF518(F) PORTABLE LOW-POWER ARCHITECTURE Blackfin processors provide world-class power management and performance. They are produced with a low power and low voltage design methodology and feature on-chip dynamic power management, which is the ability to vary both the voltage and frequency of operation to significantly lower overall power consumption. This capability can result in a substantial reduction in power consumption, compared with just varying the frequency of operation. This allows longer battery life for portable appliances. SYSTEM INTEGRATION The ADSP-BF512/BF514/BF516/BF518(F) processors are highly integrated system-on-a-chip solutions for the next generation of embedded network connected applications. By combining industry-standard interfaces with a high performance signal processing core, cost-effective applications can be developed quickly, without the need for costly external components. The system peripherals include an IEEE-compliant 802.3 10/100 Ethernet MAC with IEEE-1588 support (ADSPBF518/ADSP-BF518F only), an RSI controller, a TWI controller, two UART ports, two SPI ports, two serial ports (SPORTs), nine general purpose 32-bit timers (eight with PWM capability), three-phase PWM for motor control, a real-time clock, a watchdog timer, and a parallel peripheral interface (PPI).

The processors contain dedicated network communication modules and high speed serial and parallel ports, an interrupt controller for flexible management of interrupts from the on-chip peripherals or external sources, and power management control functions to tailor the performance and power characteristics of the processor and system to many application scenarios. All of the peripherals, except for the general-purpose I/O, rotary counter, TWI, three-phase PWM, real-time clock, and timers, are supported by a flexible DMA structure. There are also separate memory DMA channels dedicated to data transfers between the processor's various memory spaces, including external SDRAM and asynchronous memory. Multiple on-chip buses provide enough bandwidth to keep the processor core running along with activity on all of the on-chip and external peripherals. 32K 32K 4K 32K 400 MHz 176-Lead LQFP 168-Ball CSP_BGA By integrating a rich set of industry-leading system peripherals and memory, Blackfin processors are the platform of choice for next-generation applications that require RISC-like programmability, multimedia support, and leading-edge signal processing in one integrated package. BLACKFIN PROCESSOR CORE As shown in Figure 1 on Page 4, the Blackfin processor core contains two 16-bit multipliers, two 40-bit accumulators, two 40-bit ALUs, four video ALUs, and a 40-bit shifter. The computation units process 8-, 16-, or 32-bit data from the register file. Rev. PrE | Page 3 of 62 | March 2009 ADSP-BF512/BF514/BF516/BF518(F) The compute register file contains eight 32-bit registers. When performing compute operations on 16-bit operand data, the register file operates as 16 independent 16-bit registers. All operands for compute operations come from the multiported register file and instruction constant fields.

Blackfin Processor Core Each MAC can perform a 16-bit by 16-bit multiply in each cycle, accumulating the results into the 40-bit accumulators. Signed and unsigned formats, rounding, and saturation are supported. The ALUs perform a traditional set of arithmetic and logical operations on 16-bit or 32-bit data. In addition, many special instructions are included to accelerate various signal processing tasks. These include bit operations such as field extract and population count, modulo 232 multiply, divide primitives, saturation and rounding, and sign/exponent detection. The set of video instructions include byte alignment and packing operations, 16-bit and 8-bit adds with clipping, 8-bit average operations, and 8-bit subtract/absolute value/accumulate (SAA) operations. Also provided are the compare/select and vector search instructions. For certain instructions, two 16-bit ALU operations can be performed simultaneously on register pairs (a 16-bit high half and 16-bit low half of a compute register). If the second ALU is used, quad 16-bit operations are possible. Rev. PrE | The 40-bit shifter can perform shifts and rotates and is used to support normalization, field extract, and field deposit instructions. The program sequencer controls the flow of instruction execution, including instruction alignment and decoding. For program flow control, the sequencer supports PC relative and indirect conditional jumps (with static branch prediction), and subroutine calls. Hardware is provided to support zero-overhead looping. The architecture is fully interlocked, meaning that the programmer need not manage the pipeline when executing instructions with data dependencies. The address arithmetic unit provides two addresses for simultaneous dual fetches from memory. It contains a multiported register file consisting of four sets of 32-bit index, modify, length, and base registers (for circular buffering), and eight additional 32-bit pointer registers (for C-style indexed stack manipulation). Page 4 of 62 | March 2009 Preliminary Technical Data Blackfin processors support a modified Harvard architecture in combination with a hierarchical memory structure. Level 1 (L1) memories are those that typically operate at the full processor speed with little or no latency. At the L1 level, the instruction memory holds instructions only. The two data memories hold data, and a dedicated scratchpad data memory stores stack and local variable information. In addition, multiple L1 memory blocks are provided, offering a configurable mix of SRAM and cache. The memory management unit (MMU) provides memory protection for individual tasks that may be operating on the core and can protect system registers from unintended access. The architecture provides three modes of operation: user mode, supervisor mode, and emulation mode. User mode has restricted access to certain system resources, thus providing a protected software environment, while supervisor mode has unrestricted access to the system and core resources. The Blackfin processor instruction set has been optimized so that 16-bit opcodes represent the most frequently used instructions, resulting in excellent compiled code density. Complex DSP instructions are encoded into 32-bit opcodes, representing fully featured multifunction instructions. Blackfin processors support a limited multi-issue capability, where a 32-bit instruction can be issued in parallel with two 16-bit instructions, allowing the programmer to use many of the core resources in a single instruction cycle. The Blackfin processor assembly language uses an algebraic syntax for ease of coding and readability. The architecture has been optimized for use in conjunction with the C/C++ compiler, resulting in fast and efficient software implementations.

All resources, including internal memory, external memory, and I/O control registers, occupy separate sections of this common address space. The memory portions of this address space are arranged in a hierarchical structure to provide a good cost/performance balance of some very fast, low-latency on-chip memory as cache or SRAM, and larger, lower-cost and performance off-chip memory systems. See Figure 2. The on-chip L1 memory system is the highest-performance memory available to the Blackfin processor. The off-chip memory system, accessed through the external bus interface unit (EBIU), provides expansion with SDRAM, flash memory, and SRAM, optionally accessing up to 132M bytes of physical memory. The memory DMA controller provides high-bandwidth datamovement capability. It can perform block transfers of code or data between the internal memory and the external memory spaces. Figure 2. ADSP-BF512/BF514/BF516/BF518(F) Internal/External Memory Map The first block is the L1 instruction memory, consisting of 48K bytes SRAM, of which 16K bytes can be configured as a four-way set-associative cache. This memory is accessed at full processor speed. The second on-chip memory block is the L1 data memory, consisting of up to two banks of up to 32K bytes each. Each memory bank is configurable, offering both cache and SRAM functionality. This memory block is accessed at full processor speed. The third memory block is a 4K byte scratchpad SRAM which runs at the same speed as the L1 memories, but is only accessible as data SRAM and cannot be configured as cache memory. External (Off-Chip) Memory External memory is accessed via the EBIU. This 16-bit interface provides a glueless connection to a bank of synchronous DRAM (SDRAM) as well as up to four banks of asynchronous memory devices including flash, EPROM, ROM, SRAM, and memory mapped I/O devices. The SDRAM controller can be programmed to interface to up to 128M bytes of SDRAM. A separate row can be open for each SDRAM internal bank and the SDRAM controller supports up to four internal SDRAM banks, improving overall performance. Internal (On-Chip) Memory The ADSP-BF512/BF514/BF516/BF518(F) processors have three blocks of on-chip memory providing high-bandwidth access to the core. Rev. PrE | Page 5 of 62 | March 2009 ADSP-BF512/BF514/BF516/BF518(F) The asynchronous memory controller can be programmed to control up to four banks of devices with very flexible timing parameters for a wide variety of devices. Each bank occupies a 1M byte segment regardless of the size of the devices used, so that these banks are only contiguous if each is fully populated with 1M byte of memory. Preliminary Technical Data Booting The processors contain a small on-chip boot kernel, which configures the appropriate peripheral for booting. If the processors are configured to boot from boot ROM memory space, the processor starts executing from the on-chip boot ROM. For more information, see Booting Modes on Page 17. Flash Memory The ADSP-BF512F/ADSP-BF514F/ADSP-BF516F/ ADSP-BF518F processors contain a SPI flash memory within the package of the processor and connected to SPI0. The SPI flash memory has a 4M bit capacity and 1.8V (nominal) operating voltage. The program/erase endurance is 100,000 cycles per block, and this memory has greater than 100 years data retention capability. Also included are support for software write protection and support for fast erase and byte-program. The processors internally connect to the flash memory die with the MOSI, MISO, SPISSEL, and SPI_CLK signals similar to an external SPI flash. To further provide a secure processing environment, these internally connected signals are not exposed outside of the package. For this reason, programming the ADSP-BF51xF flash memory is performed by running code on the processor. It cannot be programmed from external signals and data transfers between the SPI flash and the processor cannot be probed externally. Event Handling The event controller handles all asynchronous and synchronous events to the processor. The processors provide event handling that supports both nesting and prioritization. Nesting allows multiple event service routines to be active simultaneously. Prioritization ensures that servicing of a higher-priority event takes precedence over servicing of a lower-priority event. The controller provides support for five different types of events: • Emulation – An emulation event causes the processor to enter emulation mode, allowing command and control of the processor through the JTAG interface. • Reset – This event resets the processor. • Nonmaskable Interrupt (NMI) – The NMI event can be generated by the software watchdog timer or by the NMI input signal to the processor. The NMI event is frequently used as a power-down indicator to initiate an orderly shutdown of the system. • Exceptions – Events that occur synchronously to program flow; that is, the exception is taken before the instruction is allowed to complete. Conditions such as data alignment violations and undefined instructions cause exceptions. • Interrupts – Events that occur asynchronously to program flow. They are caused by input signals, timers, and other peripherals, as well as by an explicit software instruction. Each event type has an associated register to hold the return address and an associated return-from-event instruction. When an event is triggered, the state of the processor is saved on the supervisor stack. The event controller consists of two stages, the core event controller (CEC) and the system interrupt controller (SIC). The core event controller works with the system interrupt controller to prioritize and control all system events. Conceptually, interrupts from the peripherals enter into the SIC, and are then routed directly into the general-purpose interrupts of the CEC. One-Time Programmable Memory The processors have 64K bits of one-time programmable nonvolatile memory that can be programmed by the developer only one time. It includes the array and logic to support read access and programming. Additionally, its pages can be write protected. OTP enables developers to store both public and private data on-chip. In addition to storing public and private key data for applications requiring security, it also allows developers to store completely user-definable data such as customer ID, product ID, and MAC address. Hence generic parts can be shipped which are then programmed and protected by the developer within this non-volatile memory. I/O Memory Space The processors do not define a separate I/O space. All resources are mapped through the flat 32-bit address space. On-chip I/O devices have their control registers mapped into memorymapped registers (MMRs) at addresses near the top of the 4G byte address space. These are separated into two smaller blocks, one which contains the control MMRs for all core functions, and the other which contains the registers needed for setup and control of the on-chip peripherals outside of the core. The MMRs are accessible only in supervisor mode and appear as reserved space to on-chip peripherals. Core Event Controller (CEC) The CEC supports nine general-purpose interrupts (IVG15–7), in addition to the dedicated interrupt and exception events. Of these general-purpose interrupts, the two lowest-priority interrupts (IVG15–14) are recommended to be reserved for software interrupt handlers, leaving seven prioritized interrupt inputs to support the peripherals of the processors. Table 2 describes the inputs to the CEC, identifies their names in the event vector table (EVT), and lists their priorities. Rev. PrE | Page 6 of 62 | March 2009 Preliminary Technical Data Table 2.

Table 3 describes the inputs into the SIC and the default mappings into the CEC. Event Control The ADSP-BF512/BF514/BF516/BF518(F) processors provide a very flexible mechanism to control the processing of events. In the CEC, three registers are used to coordinate and control events. Each register is 16 bits wide. • CEC interrupt latch register (ILAT) – Indicates when events have been latched. The appropriate bit is set when the processor has latched the event and cleared when the event has been accepted into the system. This register is updated automatically by the controller, but it may be written only when its corresponding IMASK bit is cleared. • CEC interrupt mask register (IMASK) – Controls the masking and unmasking of individual events. When a bit is set in the IMASK register, that event is unmasked and is processed by the CEC when asserted. A cleared bit in the IMASK register masks the event, preventing the processor from servicing the event even though the event may be latched in the ILAT register. This register may be read or written while in supervisor mode. (Note that general-purpose interrupts can be globally enabled and disabled with the STI and CLI instructions, respectively.) • CEC interrupt pending register (IPEND) – The IPEND register keeps track of all nested events. A set bit in the IPEND register indicates the event is currently active or nested at some level. This register is updated automatically by the controller but may be read while in supervisor mode. System Interrupt Controller (SIC) The system interrupt controller provides the mapping and routing of events from the many peripheral interrupt sources to the prioritized general-purpose interrupt inputs of the CEC. Although the processors provide a default mapping, the user can alter the mappings and priorities of interrupt events by writTable 3.

PrE | Page 8 of 62 | March 2009 Preliminary Technical Data The SIC allows further control of event processing by providing three pairs of 32-bit interrupt control and status registers. Each register contains a bit corresponding to each of the peripheral interrupt events shown in Table 3 on Page 7. • SIC interrupt mask registers (SIC_IMASKx) – Control the masking and unmasking of each peripheral interrupt event. When a bit is set in these registers, that peripheral event is unmasked and is processed by the system when asserted. A cleared bit in the register masks the peripheral event, preventing the processor from servicing the event. • SIC interrupt status registers (SIC_ISRx) – As multiple peripherals can be mapped to a single event, these registers allow the software to determine which peripheral event source triggered the interrupt. A set bit indicates the peripheral is asserting the interrupt, and a cleared bit indicates the peripheral is not asserting the event. • SIC interrupt wakeup enable registers (SIC_IWRx) – By enabling the corresponding bit in these registers, a peripheral can be configured to wake up the processor, should the core be idled when the event is generated. For more information see Dynamic Power Management on Page 14. Because multiple interrupt sources can map to a single generalpurpose interrupt, multiple pulse assertions can occur simultaneously, before or during interrupt processing for an interrupt event already detected on this interrupt input. The IPEND register contents are monitored by the SIC as the interrupt acknowledgement. The appropriate ILAT register bit is set when an interrupt rising edge is detected (detection requires two core clock cycles). The bit is cleared when the respective IPEND register bit is set. The IPEND bit indicates that the event has entered into the processor pipeline. At this point the CEC recognizes and queues the next rising edge event on the corresponding event input. The minimum latency from the rising edge transition of the generalpurpose interrupt to the IPEND output asserted is three core clock cycles; however, the latency can be much higher, depending on the activity within and the state of the processor. ADSP-BF512/BF514/BF516/BF518(F) The 2-D DMA capability supports arbitrary row and column sizes up to 64K elements by 64K elements, and arbitrary row and column step sizes up to ±32K elements. Furthermore, the column step size can be less than the row step size, allowing implementation of interleaved data streams. This feature is especially useful in video applications where data can be deinterleaved on the fly. Examples of DMA types supported by the DMA controller include: • A single, linear buffer that stops upon completion • A circular, auto-refreshing buffer that interrupts on each full or fractionally full buffer • 1-D or 2-D DMA using a linked list of descriptors • 2-D DMA using an array of descriptors, specifying only the base DMA address within a common page In addition to the dedicated peripheral DMA channels, there are two memory DMA channels that transfer data between the various memories of the processor system. This enables transfers of blocks of data between any of the memories—including external SDRAM, ROM, SRAM, and flash memory—with minimal processor intervention. Memory DMA transfers can be controlled by a very flexible descriptor-based methodology or by a standard register-based autobuffer mechanism. The processors also have an external DMA controller capability via dual external DMA request signals when used in conjunction with the external bus interface unit (EBIU). This functionality can be used when a high speed interface is required for external FIFOs and high bandwidth communications peripherals. It allows control of the number of data transfers for memory DMA. The number of transfers per edge is programmable. This feature can be programmed to allow memory DMA to have an increased priority on the external bus relative to the core. REAL-TIME CLOCK The real-time clock (RTC) provides a robust set of digital watch features, including current time, stopwatch, and alarm. The RTC is clocked by a 32.768 kHz crystal external to the processors. The RTC peripheral has a dedicated power supply so that it can remain powered up and clocked even when the rest of the processor is in a low-power state. The RTC provides several programmable interrupt options, including interrupt per second, minute, hour, or day clock ticks, interrupt on programmable stopwatch countdown, or interrupt at a programmed alarm time. The 32.768 kHz input clock frequency is divided down to a 1 Hz signal by a prescaler. The counter function of the timer consists of four counters: a 60-second counter, a 60-minute counter, a 24-hour counter, and an 32,768-day counter. When enabled, the alarm function generates an interrupt when the output of the timer matches the programmed value in the alarm control register. There are two alarms: The first alarm is for a time of day. The second alarm is for a day and time of that day. DMA CONTROLLERS The ADSP-BF512/BF514/BF516/BF518(F) processors have multiple, independent DMA channels that support automated data transfers with minimal overhead for the processor core. DMA transfers can occur between the processor's internal memories and any of its DMA-capable peripherals. Additionally, DMA transfers can be accomplished between any of the DMA-capable peripherals and external devices connected to the external memory interfaces, including the SDRAM controller and the asynchronous memory controller. DMA-capable peripherals include the Ethernet MAC, RSI, SPORTs, SPIs, UARTs, and PPI. Each individual DMA-capable peripheral has at least one dedicated DMA channel. The processors’ DMA controller supports both one-dimensional (1-D) and two-dimensional (2-D) DMA transfers. DMA transfer initialization can be implemented from registers or from sets of parameters called descriptor blocks. Rev. PrE | Page 9 of 62 | March 2009 ADSP-BF512/BF514/BF516/BF518(F) The stopwatch function counts down from a programmed value, with one-second resolution. When the stopwatch is enabled and the counter underflows, an interrupt is generated. Like the other peripherals, the RTC can wake up the processor from sleep mode upon generation of any RTC wakeup event. Additionally, an RTC wakeup event can wake up the processor from deep sleep mode or cause a transition from the hibernate state. Connect RTC signals RTXI and RTXO with external components as shown in Figure 3. RTXI R1 RTXO Preliminary Technical Data pulse width modulator (PWM) or timer output, as an input to clock the timer, or as a mechanism for measuring pulse widths and periods of external events. These timers can be synchronized to an external clock input to the several other associated PF signals, an external clock input to the PPI_CLK input signal, or to the internal SCLK. The timer units can be used in conjunction with the two UARTs to measure the width of the pulses in the data stream to provide a software auto-baud detect function for the respective serial channels. The timers can generate interrupts to the processor core providing periodic events for synchronization, either to the system clock or to a count of external signals. In addition to the eight general-purpose programmable timers, a ninth timer is also provided. This extra timer is clocked by the internal processor clock and is typically used as a system tick clock for generation of operating system periodic interrupts.

In addition, the PWM block contains special functions that considerably simplify the generation of the required PWM switching patterns for control of the electronically commutated motor (ECM) or brushless dc motor (BDCM). Software can enable a special mode for switched reluctance motors (SRM). The six PWM output signals consist of three high-side drive signals (PWM_AH, PWM_BH, and PWM_CH) and three low-side drive signals (PWM_AL, PWM_BL, and PWM_CL). The polarity of the generated PWM signal be set with software, so that either active HI or active LO PWM patterns can be produced. The switching frequency of the generated PWM pattern is programmable using the 16-bit PWMTM register. The PWM generator can operate in single update mode or double update March 2009 Figure 3. External Components for RTCT WATCHDOG TIMER The ADSP-BF512/BF514/BF516/BF518(F) processors include a 32-bit timer that can be used to implement a software watchdog function. A software watchdog can improve system availability by forcing the processor to a known state through generation of a hardware reset, nonmaskable interrupt (NMI), or generalpurpose interrupt, if the timer expires before being reset by software. The programmer initializes the count value of the timer, enables the appropriate interrupt, then enables the timer. Thereafter, the software must reload the counter before it counts to zero from the programmed value. This protects the system from remaining in an unknown state where software, which would normally reset the timer, has stopped running due to an external noise condition or software error. If configured to generate a hardware reset, the watchdog timer resets both the core and the processor peripherals. After a reset, software can determine if the watchdog was the source of the hardware reset by interrogating a status bit in the watchdog timer control register. The timer is clocked by the system clock (SCLK), at a maximum frequency of fSCLK. TIMERS There are nine general-purpose programmable timer units in the ADSP-BF512/BF514/BF516/BF518(F) processors. Eight timers have an external signal that can be configured either as a Rev. PrE | Page 10 of 62 | Preliminary Technical Data mode. In single update mode the duty cycle values are programmable only once per PWM period, so that the resultant PWM patterns are symmetrical about the midpoint of the PWM period. In the double update mode, a second updating of the PWM registers is implemented at the midpoint of the PWM period. In this mode, it is possible to produce asymmetrical PWM patterns that produce lower harmonic distortion in 3-phase PWM inverters. ADSP-BF512/BF514/BF516/BF518(F) • DMA operations with single-cycle overhead – Each SPORT can automatically receive and transmit multiple buffers of memory data. The processor can link or chain sequences of DMA transfers between a SPORT and memory. • Interrupts – Each transmit and receive port generates an interrupt upon completing the transfer of a data word or after transferring an entire data buffer, or buffers, through DMA. • Multichannel capability – Each SPORT supports 128 channels out of a 1024-channel window and is compatible with the H.100, H.110, MVIP-90, and HMVIP standards. GENERAL-PURPOSE (GP) COUNTER A 32-bit GP counter is provided that can sense 2-bit quadrature or binary codes as typically emitted by industrial drives or manual thumb wheels. The counter can also operate in generalpurpose up/down count modes. Then, count direction is either controlled by a level-sensitive input signal or by two edge detectors. A third input can provide flexible zero marker support and can alternatively be used to input the push-button signal of thumb wheels. All three signals have a programmable debouncing circuit. An internal signal forwarded to the GP timer unit enables one timer to measure the intervals between count events. Boundary registers enable auto-zero operation or simple system warning by interrupts when programmable count values are exceeded. SERIAL PERIPHERAL INTERFACE (SPI) PORTS The processors have two SPI-compatible ports (SPI0 and SPI1) that enable the processor to communicate with multiple SPIcompatible devices. The SPI interface uses three signals for transferring data: two data signals (master output-slave input–MOSI, and master input-slave output–MISO) and a clock signal (serial clock–SCK). An SPI chip select input signal (SPIxSS) lets other SPI devices select the processor, and multiple SPI chip select output signals let the processor select other SPI devices. The SPI select signals are reconfigured general-purpose I/O signals. Using these signals, the SPI port provides a full-duplex, synchronous serial interface, which supports both master/slave modes and multimaster environments. The SPI port baud rate and clock phase/polarities are programmable, and it has an integrated DMA channel, configurable to support transmit or receive data streams. The SPI’s DMA channel can only service unidirectional accesses at any given time. The SPI port clock rate is calculated as: f SCLK SPI Clock Rate = ----------------------------------2 × SPI_BAUD Where the 16-bit SPI_BAUD register contains a value of 2 to 65,535. During transfers, the SPI port simultaneously transmits and receives by serially shifting data in and out on its two serial data lines. The serial clock line synchronizes the shifting and sampling of data on the two serial data lines. SERIAL PORTS The ADSP-BF512/BF514/BF516/BF518(F) processors incorporate two dual-channel synchronous serial ports (SPORT0 and SPORT1) for serial and multiprocessor communications. The SPORTs support the following features: • I2S capable operation. • Bidirectional operation – Each SPORT has two sets of independent transmit and receive signals, enabling eight channels of I2S stereo audio. • Buffered (8-deep) transmit and receive ports – Each port has a data register for transferring data words to and from other processor components and shift registers for shifting data in and out of the data registers. • Clocking – Each transmit and receive port can either use an external serial clock or generate its own, in frequencies ranging from (fSCLK/131,070) Hz to (fSCLK/2) Hz. • Word length – Each SPORT supports serial data words from 3 to 32 bits in length, transferred most-significant-bit first or least-significant-bit first. • Framing – Each transmit and receive port can run with or without frame sync signals for each data word. Frame sync signals can be generated internally or externally, active high or low, and with either of two pulse widths and early or late frame sync. • Companding in hardware – Each SPORT can perform A-law or μ-law companding according to ITU recommendation G.711. Companding can be selected on the transmit and/or receive channel of the SPORT without additional latencies. UART PORTS The ADSP-BF512/BF514/BF516/BF518(F) processors provide two full-duplex universal asynchronous receiver/transmitter (UART) ports, which are fully compatible with PC-standard UARTs. Each UART port provides a simplified UART interface to other peripherals or hosts, supporting full-duplex, DMA-supported, asynchronous transfers of serial data. A UART port Rev. PrE | Page 11 of 62 | March 2009 ADSP-BF512/BF514/BF516/BF518(F) includes support for five to eight data bits, one or two stop bits, and none, even, or odd parity. Each UART port supports two modes of operation: • PIO (programmed I/O) – The processor sends or receives data by writing or reading I/O mapped UART registers. The data is double-buffered on both transmit and receive. • DMA (direct memory access) – The DMA controller transfers both transmit and receive data. This reduces the number and frequency of interrupts required to transfer data to and from memory. The UART has two dedicated DMA channels, one for transmit and one for receive. These DMA channels have lower default priority than most DMA channels because of their relatively low service rates. Each UART port's baud rate, serial data format, error code generation and status, and interrupts are programmable: • Supporting bit rates ranging from (fSCLK/1,048,576) to (fSCLK/16) bits per second. • Supporting data formats from seven to 12 bits per frame. • Both transmit and receive operations can be configured to generate maskable interrupts to the processor. The UART port’s clock rate is calculated as: f SCLK UART Clock Rate = ---------------------------------------------16 × UART_Divisor Where the 16-bit UART_Divisor comes from the UART_DLH (most significant 8 bits) and UART_DLL (least significant 8 bits) registers. In conjunction with the general-purpose timer functions, autobaud detection is supported. The capabilities of the UARTs are further extended with support for the infrared data association (IrDA®) serial infrared physical layer link specification (SIR) protocol. Preliminary Technical Data RSI INTERFACE The removable storage interface (RSI) controller acts as the host interface for multi-media cards (MMC), secure digital memory cards (SD Card), secure digital input/output cards (SDIO), and CE-ATA hard disk drives. The following list describes the main features of the RSI controller. • Support for a single MMC, SD memory, SDIO card or CEATA hard disk drive • Support for 1-bit and 4-bit SD modes • Support for 1-bit, 4-bit and 8-bit MMC modes • Support for 4-bit and 8-bit CE-ATA hard disk drives • A ten-signal external interface with clock, command, and up to eight data lines • Card detection using one of the data signals • Card interface clock generation from SCLK • SDIO interrupt and read wait features • CE-ATA command completion signal recognition and disable 10/100 ETHERNET MAC The ADSP-BF516/BF518 processors offer the capability to directly connect to a network by way of an embedded fast Ethernet media access controller (MAC) that supports both 10-BaseT (10M bits/sec) and 100-BaseT (100M bits/sec) operation. The 10/100 Ethernet MAC peripheral on the processor is fully compliant to the IEEE 802.3-2002 standard and it provides programmable features designed to minimize supervision, bus use, or message processing by the rest of the processor system. Some standard features are: • Support of MII and RMII protocols for external PHYs • Full duplex and half duplex modes • Data framing and encapsulation: generation and detection of preamble, length padding, and FCS • Media access management (in half-duplex operation): collision and contention handling, including control of retransmission of collision frames and of back-off timing • Flow control (in full-duplex operation): generation and detection of pause frames • Station management: generation of MDC/MDIO frames for read-write access to PHY registers • SCLK operating range down to 25 MHz (active and sleep operating modes) • Internal loopback from transmit to receive Some advanced features are: • Buffered crystal output to external PHY for support of a single crystal system • Automatic checksum computation of IP header and IP payload fields of Rx frames • Independent 32-bit descriptor-driven receive and transmit DMA channels Rev. PrE | Page 12 of 62 | March 2009 TWI CONTROLLER INTERFACE The processors include a two wire interface (TWI) module for providing a simple exchange method of control data between multiple devices. The TWI is compatible with the widely used I2C® bus standard. The TWI module offers the capabilities of simultaneous master and slave operation, support for both 7-bit addressing and multimedia data arbitration. The TWI interface utilizes two signals for transferring clock (SCL) and data (SDA) and supports the protocol at speeds up to 400k bits/sec. The TWI interface signals are compatible with 5 V logic levels. Additionally, the processor’s TWI module is fully compatible with serial camera control bus (SCCB) functionality for easier control of various CMOS camera sensor devices. Preliminary Technical Data • Frame status delivery to memory through DMA, including frame completion semaphores for efficient buffer queue management in software • Tx DMA support for separate descriptors for MAC header and payload to eliminate buffer copy operations • Convenient frame alignment modes support even 32-bit alignment of encapsulated receive or transmit IP packet data in memory after the 14-byte MAC header • Programmable Ethernet event interrupt supports any combination of: • Selected receive or transmit frame status conditions • PHY interrupt condition • Wakeup frame detected • Selected MAC management counter(s) at half-full • DMA descriptor error • 47 MAC management statistics counters with selectable clear-on-read behavior and programmable interrupts on half maximum value • Programmable receive address filters, including a 64-bin address hash table for multicast and/or unicast frames, and programmable filter modes for broadcast, multicast, unicast, control, and damaged frames • Advanced power management supporting unattended transfer of receive and transmit frames and status to/from external memory via DMA during low-power sleep mode • System wakeup from sleep operating mode upon magic packet or any of four user-definable wakeup frame filters • Support for 802.3Q tagged VLAN frames • Programmable MDC clock rate and preamble suppression • In RMII operation, seven unused signals may be configured as GPIO signals for other purposes ADSP-BF512/BF514/BF516/BF518(F) • Multiple input clock sources (SCLK, MII clock, external clock up to 50 MHz) • Programmable pulse per second (PPS) output • Auxiliary snapshot to time stamp external events PORTS Because of the rich set of peripherals, the processors group the many peripheral signals to four ports—port F, port G, port H, and port J. Most of the associated pins/balls are shared by multiple signals. The ports function as multiplexer controls. General-Purpose I/O (GPIO) The ADSP-BF512/BF514/BF516/BF518(F) processors have 40 bidirectional, general-purpose I/O (GPIO) signals allocated across three separate GPIO modules—PORTFIO, PORTGIO, and PORTHIO, associated with Port F, Port G, and Port H, respectively. Each GPIO-capable signal shares functionality with other peripherals via a multiplexing scheme; however, the GPIO functionality is the default state of the device upon power-up. Neither GPIO output nor input drivers are active by default. Each general-purpose port signal can be individually controlled by manipulation of the port control, status, and interrupt registers: • GPIO direction control register – Specifies the direction of each individual GPIO signal as input or output. • GPIO control and status registers – The processor employs a “write one to modify” mechanism that allows any combination of individual GPIO signals to be modified in a single instruction, without affecting the level of any other GPIO signals. Four control registers are provided. One register is written in order to set signal values, one register is written in order to clear signal values, one register is written in order to toggle signal values, and one register is written in order to specify a signal value. Reading the GPIO status register allows software to interrogate the sense of the signals. • GPIO interrupt mask registers – The two GPIO interrupt mask registers allow each individual GPIO signal to function as an interrupt to the processor. Similar to the two GPIO control registers that are used to set and clear individual signal values, one GPIO interrupt mask register sets bits to enable interrupt function, and the other GPIO interrupt mask register clears bits to disable interrupt function. GPIO signals defined as inputs can be configured to generate hardware interrupts, while output signals can be triggered by software interrupts. • GPIO interrupt sensitivity registers – The two GPIO interrupt sensitivity registers specify whether individual signals are level- or edge-sensitive and specify—if edge-sensitive— whether just the rising edge or both the rising and falling edges of the signal are significant. One register selects the type of sensitivity, and one register selects which edges are significant for edge-sensitivity. IEEE 1588 SUPPORT The IEEE 1588 standard is a precision clock synchronization protocol for networked measurement and control systems. The ADSP-BF518/ADSP-BF518F processors include hardware support for IEEE 1588 with an integrated precision time protocol synchronization engine (PTP_TSYNC). This engine provides hardware assisted time stamping to improve the accuracy of clock synchronization between PTP nodes. The main features of the PTP_SYNC engine are: • Support for both IEEE 1588-2002 and IEEE 1588-2008 protocol standards • Hardware assisted time stamping capable of 12.5 ns resolution • Lock adjustment • Programmable PTM message support • Dedicated interrupts • Programmable alarm Rev. PrE | Page 13 of 62 | March 2009 ADSP-BF512/BF514/BF516/BF518(F) PARALLEL PERIPHERAL INTERFACE (PPI) The ADSP-BF512/BF514/BF516/BF518(F) processors provide a parallel peripheral interface (PPI) that can connect directly to parallel A/D and D/A converters, ITU-R-601/656 video encoders and decoders, and other general-purpose peripherals. The PPI consists of a dedicated input clock signal, up to three frame synchronization signals, and up to 16 data signals. In ITU-R-656 modes, the PPI receives and parses a data stream of 8-bit or 10-bit data elements. On-chip decode of embedded preamble control and synchronization information is supported. Three distinct ITU-R-656 modes are supported: • Active video only mode – The PPI does not read in any data between the End of Active Video (EAV) and Start of Active Video (SAV) preamble symbols, or any data present during the vertical blanking intervals. In this mode, the control byte sequences are not stored to memory; they are filtered by the PPI. • Vertical blanking only mode – The PPI only transfers vertical blanking interval (VBI) data, as well as horizontal blanking information and control byte sequences on VBI lines. • Entire field mode – The entire incoming bitstream is read in through the PPI. This includes active video, control preamble sequences, and ancillary data that may be embedded in horizontal and vertical blanking intervals. Though not explicitly supported, ITU-R-656 output functionality can be achieved by setting up the entire frame structure (including active video, blanking, and control information) in memory and streaming the data out the PPI in a frame sync-less mode. The processor’s 2-D DMA features facilitate this transfer by allowing the static frame buffer (blanking and control codes) to be placed in memory once, and simply updating the active video information on a per-frame basis. The general-purpose modes of the PPI are intended to suit a wide variety of data capture and transmission applications. The modes are divided into four main categories, each allowing up to 16 bits of data transfer per PPI_CLK cycle: • Data receive with internally generated frame syncs • Data receive with externally generated frame syncs • Data transmit with internally generated frame syncs • Data transmit with externally generated frame syncs These modes support ADC/DAC connections, as well as video communication with hardware signalling. Many of the modes support more than one level of frame synchronization. If desired, a programmable delay can be inserted between assertion of a frame sync and reception/transmission of data. Preliminary Technical Data CODE SECURITY WITH LOCKBOX SECURE TECHNOLOGY A security system consisting of a blend of hardware and software provides customers with a flexible and rich set of code security features with Lockbox secure technology. Key features include: • OTP memory • Unique chip ID • Code authentication • Secure mode of operation The security scheme is based upon the concept of authentication of digital signatures using standards-based algorithms and provides a secure processing environment in which to execute code and protect assets. DYNAMIC POWER MANAGEMENT The ADSP-BF512/BF514/BF516/BF518(F) processors provide four operating modes, each with a different performance/power profile. In addition, dynamic power management provides the control functions to dynamically alter the processor core supply voltage, further reducing power dissipation. When configured for a 0 volt core supply voltage, the processor enters the hibernate state. Control of clocking to each of the processor peripherals also reduces power consumption. See Table 4 for a summary of the power settings for each mode. Table 4. Power Settings Core PLL Clock Bypassed (CCLK) System Clock (SCLK) Core Power Mode/State PLL Full On Active Sleep Deep Sleep Hibernate Enabled No Enabled/ Yes Disabled Enabled — Disabled — Disabled — Enabled Enabled On Enabled Enabled On Disabled Enabled On Disabled Disabled On Disabled Disabled Off Full-On Operating Mode—Maximum Performance In the full-on mode, the PLL is enabled and is not bypassed, providing capability for maximum operational frequency. This is the power-up default execution state in which maximum performance can be achieved. The processor core and all enabled peripherals run at full speed. Active Operating Mode—Moderate Power Savings In the active mode, the PLL is enabled but bypassed. Because the PLL is bypassed, the processor’s core clock (CCLK) and system clock (SCLK) run at the input clock (CLKIN) frequency. In this mode, the CLKIN to CCLK multiplier ratio can be changed, although the changes are not realized until the full-on mode is entered. DMA access is available to appropriately configured L1 memories. Rev. PrE | Page 14 of 62 | March 2009 Preliminary Technical Data In the active mode, it is possible to disable the PLL through the PLL control register (PLL_CTL). If disabled, the PLL must be re-enabled before transitioning to the full-on or sleep modes. ADSP-BF512/BF514/BF516/BF518(F) SDRAM. The SCKELOW bit in the VR_CTL register controls whether or not SDRAM operates in self-refresh mode, which allows it to retain its content while the processor is in hibernation and through the subsequent reset sequence. Sleep Operating Mode—High Dynamic Power Savings The sleep mode reduces dynamic power dissipation by disabling the clock to the processor core (CCLK). The PLL and system clock (SCLK), however, continue to operate in this mode. Typically an external event or RTC activity wakes up the processor. When in the sleep mode, asserting wakeup causes the processor to sense the value of the BYPASS bit in the PLL control register (PLL_CTL). If BYPASS is disabled, the processor transitions to the full on mode. If BYPASS is enabled, the processor transitions to the active mode. System DMA access to L1 memory is not supported in sleep mode. Power Savings As shown in Table 5, the processors support up to six different power domains, which maximizes flexibility while maintaining compliance with industry standards and conventions. By isolating the internal logic of the processor into its own power domain, separate from the RTC and other I/O, the processor can take advantage of dynamic power management without affecting the RTC or other I/O devices. There are no sequencing requirements for the various power domains, but all domains must be powered according to the appropriate Specifications table for processor Operating Conditions; even if the feature/peripheral is not used. Table 5. Power Domains Power Domain All internal logic, except RTC, Memory, OTP RTC internal logic and crystal I/O Memory logic OTP logic Optional internal flash All other I/O VDD Range VDDINT VDDRTC VDDMEM VDDOTP VDDFLASH VDDEXT Deep Sleep Operating Mode—Maximum Dynamic Power Savings The deep sleep mode maximizes dynamic power savings by disabling the clocks to the processor core (CCLK) and to all synchronous peripherals (SCLK). Asynchronous peripherals, such as the RTC, may still be running but cannot access internal resources or external memory. This powered-down mode can only be exited by assertion of the reset interrupt (RESET) or by an asynchronous interrupt generated by the RTC. When in deep sleep mode, an RTC asynchronous interrupt causes the processor to transition to the Active mode. Assertion of RESET while in deep sleep mode causes the processor to transition to the full on mode. Hibernate State—Maximum Static Power Savings The hibernate state maximizes static power savings by disabling the voltage and clocks to the processor core (CCLK) and system blocks (SCLK). Any critical information stored internally (memory contents, register contents, etc.) must be written to a non-volatile storage device prior to removing power if the processor state is to be preserved. Writing b#00 to the FREQ bits in the VR_CTL register also causes EXT_WAKE to transition low, which can be used to signal an external voltage regulator to shut down. Since VDDEXT is still supplied in this mode, all of the external signals three-state, unless otherwise specified. This allows other devices that may be connected to the processor to still have power applied without drawing unwanted current. The Ethernet module can signal an external regulator to wake up using EXT_WAKE. If PF15 does not connect as a PHYINT signal to an external PHY device, it can be pulled low by any other device to wake the processor up. The processor can also be woken up by a real-time clock wakeup event or by asserting the RESET pin. All hibernate wakeup events initiate the hardware reset sequence. Individual sources are enabled by the VR_CTL register. The EXT_WAKE signal is provided to indicate the occurrence of wakeup events. With the exception of the VR_CTL and the RTC registers, all internal registers and memories lose their content in the hibernate state. State variables may be held in external SRAM or Rev. PrE | The dynamic power management feature of the processor allows both the processor’s input voltage (VDDINT) and clock frequency (fCCLK) to be dynamically controlled. The power dissipated by a processor is largely a function of its clock frequency and the square of the operating voltage. For example, reducing the clock frequency by 25% results in a 25% reduction in dynamic power dissipation, while reducing the voltage by 25% reduces dynamic power dissipation by more than 40%. Further, these power savings are additive, in that if the clock frequency and supply voltage are both reduced, the power savings can be dramatic, as shown in the following equations.

To reduce standby power consumption in the hibernate state, the external voltage regulator can be signaled through EXT_WAKE to remove power from the processor core. EXT_WAKE is hightrue for power-up and may be connected directly to the lowtrue shut down input of many common regulators. The Power Good (PG) input signal allows the processor to start only after the internal voltage has reached a chosen level. In this way, the startup time of the external regulator is detected after hibernation. For a complete description of the PG functionality, refer to the ADSP-BF51x Blackfin Processor Hardware Reference.

CLOCK SIGNALS The ADSP-BF512/BF514/BF516/BF518(F) processors can be clocked by an external crystal, a sine wave input, or a buffered, shaped clock derived from an external clock oscillator. If an external clock is used, it should be a TTL compatible signal and must not be halted, changed, or operated below the specified frequency during normal operation. This signal is connected to the processor CLKIN signal. When an external clock is used, the XTAL pin/ball must be left unconnected. Alternatively, because the processor includes an on-chip oscillator circuit, an external crystal may be used. For fundamental frequency operation, use the circuit shown in Figure 4. A parallel-resonant, fundamental frequency, microprocessor-grade crystal is connected across the CLKIN and XTAL pins/balls. The on-chip resistance between the CLKIN pin/ball and the XTAL pin/ball is in the 500 kΩ range. Further parallel resistors are typically not recommended. The two capacitors and the series resistor shown in Figure 4 fine tune phase and amplitude of the sine frequency. The capacitor and resistor values shown in Figure 4 are typical values only. The capacitor values are dependent upon the crystal manufacturers’ load capacitance recommendations and the PCB physical layout. The resistor value depends on the drive level specified by the crystal manufacturer. The user should verify the customized values based on careful investigations on multiple devices over temperature range. A third-overtone crystal can be used for frequencies above 25 MHz. The circuit is then modified to ensure crystal operation only at the third overtone, by adding a tuned inductor circuit as shown in Figure 4. A design procedure for third-overtone operation is discussed in detail in application note (EE-168) Using Third Overtone Crystals with the ADSP-218x DSP on the Analog Devices website (www.analog.com)—use site search on “EE-168.” The CLKBUF signal is an output signal, which is a buffered version of the input clock. This signal is particularly useful in Ethernet applications to limit the number of required clock sources in the system. In this type of application, a single Figure 4. External Crystal Connections 25 MHz or 50 MHz crystal may be applied directly to the processor. The 25 MHz or 50 MHz output of CLKBUF can then be connected to an external Ethernet MII or RMII PHY device. The Blackfin core runs at a different clock rate than the on-chip peripherals. As shown in Figure 5, the core clock (CCLK) and system peripheral clock (SCLK) are derived from the input clock (CLKIN) signal. An on-chip PLL is capable of multiplying the CLKIN signal by a programmable 0.5× to 64× multiplication factor (bounded by specified minimum and maximum VCO frequencies). The default multiplier is 5×, but it can be modified by a software instruction sequence. On-the-fly frequency changes can be effected by simply writing to the PLL_DIV register. The maximum allowed CCLK and SCLK rates depend on the applied voltages VDDINT, VDDEXT, and VDDMEM, the VCO is always permitted to run up to the frequency specified by the part’s speed grade. The CLKOUT signal reflects the SCLK frequency to the off-chip world. It belongs to the SDRAM interface, but it functions as reference signal in other timing specifications as well. While active by default, it can be disabled using the EBIU_SDGCTL and EBIU_AMGCTL registers. “FINE” ADJU STMENT REQUIRE S PLL SEQUENCING “COAR SE” ADJU STMENT ON-THE-FLY ÷ 1, 2, 4, 8 CLKIN PLL 0.5 × to 64 × CCLK VCO ÷ 1 to 15 SCLK SCLK ≤ CCLK SCLK ≤ 80 MHz Figure 5. Frequency Modification Methods Rev. PrE | Page 16 of 62 | March 2009 Preliminary Technical Data All on-chip peripherals are clocked by the system clock (SCLK). The system clock frequency is programmable by means of the SSEL3–0 bits of the PLL_DIV register. The values programmed into the SSEL fields define a divide ratio between the PLL output (VCO) and the system clock. SCLK divider values are 1 through 15. Table 6 illustrates typical system clock ratios. Note that the divisor ratio must be chosen to limit the system clock frequency to its maximum of fSCLK. The SSEL value can be changed dynamically without any PLL lock latencies by writing the appropriate values to the PLL divisor register (PLL_DIV). Table 6.

Supported CCLK divider ratios are 1, 2, 4, and 8, as shown in Table 7. This programmable core clock capability is useful for fast core frequency modifications. Table 7.

The idle boot mode helps recover from illegal operating modes, such as when the user has mis configured the OTP memory. • Boot from 8-bit or 16-bit external flash memory (BMODE = 0x1) — In this mode, the boot kernel loads the first block header from address 0x2000 0000 and—depending on instructions containing in the header—the boot kernel performs 8-bit or 16-bit boot or starts program execution at the address provided by the header. By default, all configuration settings are set for the slowest device possible (3-cycle hold time, 15-cycle R/W access times, 4-cycle setup). The ARDY is not enabled by default, but it can be enabled by OTP programming. Similarly, all interface behavior and timings can be customized by OTP programming. This includes activation of burst-mode or page-mode operation. In this mode, all signals belonging to the asynchronous interface are enabled at the port muxing level. • Boot from internal SPI memory (BMODE = 0x2) — The processor uses SPI0 to load from code previously loaded to the 4 Mbit internal SPI flash. Only available on the ADSPBF512F/ADSP-BF514F/ADSP-BF516F/ADSP-BF518F. • Boot from external SPI EEPROM or flash (BMODE = 0x3) — 8-bit, 16-bit, 24-bit or 32-bit addressable devices are supported. The processor uses the PG15 GPIO signal (at SPI0SSEL2) to select a single SPI EEPROM/flash device connected to the SPI0 interface; then submits a read command and successive address bytes (0x00) until a valid 8-, 16-, 24-, or 32-bit addressable device is detected. Pull-up resistors are required on the SSEL and MISO signals. By default, a value of 0x85 is written to the SPI0_BAUD register. • Boot from SPI0 host device (BMODE = 0x4) — The processor operates in SPI slave mode and is configured to receive the bytes of the LDR file from an SPI host (master) agent. In the host, the HWAIT signal must be interrogated Signal Name CSEL1–0 00 01 10 11 The maximum CCLK frequency not only depends on the part's speed grade (see Page 62), it also depends on the applied VDDINT voltage. See Table 11 for details. The maximal system clock rate (SCLK) depends on the chip package and the applied VDDINT, VDDEXT, and VDDMEM voltages (see Table 14 on Page 24). BOOTING MODES The processor has several mechanisms (listed in Table 8) for automatically loading internal and external memory after a reset. The boot mode is defined by three BMODE input bits dedicated to this purpose. There are two categories of boot modes. In master boot modes the processor actively loads data from parallel or serial memories. In slave boot modes the processor receives data from external host devices. The boot modes listed in Table 8 provide a number of mechanisms for automatically loading the processor’s internal and external memories after a reset. By default, all boot modes use the slowest meaningful configuration settings. Default settings can be altered via the initialization code feature at boot time or Rev. PrE | Page 17 of 62 | March 2009 ADSP-BF512/BF514/BF516/BF518(F) by the host before every transmitted byte. A pull-up resistor is required on the SPI0SS input. A pull-down on the serial clock may improve signal quality and booting robustness. • Boot from OTP memory (BMODE = 0x5) — This provides a stand-alone booting method. The boot stream is loaded from on-chip OTP memory. By default the boot stream is expected to start from OTP page 0x40 on and can occupy all public OTP memory up to page 0xDF. This is 2560 bytes. Since the start page is programmable the maximum size of the boot stream can be extended to 3072 bytes. • Boot from SDRAM (BMODE = 0x6) This is a warm boot scenario, where the boot kernel starts booting from address 0x0000 0010. The SDRAM is expected to contain a valid boot stream and the SDRAM controller must be configured by the OTP settings. • Boot from UART0 host (BMODE = 0x7) — Using an autobaud handshake sequence, a boot-stream formatted program is downloaded by the host. The host selects a bit rate within the UART clocking capabilities. When performing the autobaud, the UART expects a “@” (0x40) character (eight bits data, one start bit, one stop bit, no parity bit) on the RX0 signal to determine the bit rate. The UART then replies with an acknowledgement composed of 4 bytes (0xBF—the value of UART0_DLL and 0x00—the value of UART0_DLH). The host can then download the boot stream. To hold off the host the Blackfin processor signals the host with the boot host wait (HWAIT) signal. Therefore, the host must monitor HWAIT before every transmitted byte. For each of the boot modes, a 16-byte header is first read from an external memory device. The header specifies the number of bytes to be transferred and the memory destination address. Multiple memory blocks may be loaded by any boot sequence. Once all blocks are loaded, program execution commences from the address stored in the EVT1 register. Prior to booting, the pre-boot routine interrogates the OTP memory. Individual boot modes can be customized or even disabled based on OTP programming. External hardware, especially booting hosts may watch the HWAIT signal to determine when the pre-boot has finished and the boot kernel starts the boot process. By programming OTP memory, the user can instruct the preboot routine to also customize the PLL, the SDRAM Controller, and the Asynchronous Interface. The boot kernel differentiates between a regular hardware reset and a wakeup-from-hibernate event to speed up booting in the later case. Bits 6-4 in the system reset configuration (SYSCR) register can be used to bypass pre-boot routine and/or boot kernel in case of a software reset. They can also be used to simulate a wakeup-from-hibernate boot in the software reset case. The boot process can be further customized by “initialization code.” This is a piece of code that is loaded and executed prior to the regular application boot. Typically, this is used to configure the SDRAM controller or to speed up booting by managing PLL, clock frequencies, wait states, or serial bit rates. Preliminary Technical Data The boot ROM also features C-callable function entries that can be called by the user application at run time. This enables second-stage boot or boot management schemes to be implemented with ease. INSTRUCTION SET DESCRIPTION The Blackfin processor family assembly language instruction set employs an algebraic syntax designed for ease of coding and readability. The instructions have been specifically tuned to provide a flexible, densely encoded instruction set that compiles to a very small final memory size. The instruction set also provides fully featured multifunction instructions that allow the programmer to use many of the processor core resources in a single instruction. Coupled with many features more often seen on microcontrollers, this instruction set is very efficient when compiling C and C++ source code. In addition, the architecture supports both user (algorithm/application code) and supervisor (O/S kernel, device drivers, debuggers, ISRs) modes of operation, allowing multiple levels of access to core processor resources. The assembly language, which takes advantage of the processor’s unique architecture, offers the following advantages: • Seamlessly integrated DSP/MCU features are optimized for both 8-bit and 16-bit operations. • A multi-issue load/store modified-harvard architecture, which supports two 16-bit MACs or four 8-bit ALUs plus two load/store plus two pointer updates per cycle. • All registers, I/O, and memory are mapped into a unified 4G byte memory space, providing a simplified programming model. • Microcontroller features, such as arbitrary bit and bit-field manipulation, insertion, and extraction; integer operations on 8-, 16-, and 32-bit data-types; and separate user and supervisor stack pointers. • Code density enhancements, which include intermixing of 16-bit and 32-bit instructions (no mode switching, no code segregation). Frequently used instructions are encoded in 16 bits. DEVELOPMENT TOOLS The ADSP-BF512/BF514/BF516/BF518(F) processors are supported with a complete set of CROSSCORE® software and hardware development tools, including Analog Devices emulators and VisualDSP++® development environment. The same emulator hardware that supports other Blackfin processors also fully emulates the ADSP-BF512/BF514/BF516/BF518(F) processors. EZ-KIT Lite Evaluation Board For evaluation of the processors, use the EZ-KIT Lite® board being developed by Analog Devices. The board comes with onchip emulation capabilities and is equipped to enable software development. Multiple daughter cards are available. Rev. PrE | Page 18 of 62 | March 2009 Preliminary Technical Data DESIGNING AN EMULATOR-COMPATIBLE PROCESSOR BOARD (TARGET) The Analog Devices family of emulators are tools that every system developer needs in order to test and debug hardware and software systems. Analog Devices has supplied an IEEE 1149.1 JTAG Test Access Port (TAP) on each JTAG processor. The emulator uses the TAP to access the internal features of the processor, allowing the developer to load code, set breakpoints, observe variables, observe memory, and examine registers. The processor must be halted to send data and commands, but once an operation has been completed by the emulator, the processor system is set running at full speed with no impact on system timing. To use these emulators, the target board must include a header that connects the processor’s JTAG port to the emulator. For details on target board design issues including mechanical layout, single processor connections, multiprocessor scan chains, signal buffering, signal termination, and emulator pod logic, see (EE-68) Analog Devices JTAG Emulation Technical Reference on the Analog Devices website (www.analog.com)— use site search on “EE-68.” This document is updated regularly to keep pace with improvements to emulator support.

Rev. PrE | Page 19 of 62 | March 2009 ADSP-BF512/BF514/BF516/BF518(F) SIGNAL DESCRIPTIONS The processors’ signal definitions are listed in Table 9. In order to maintain maximum function and reduce package size and signal count, some signals have dual, multiplexed functions. In cases where signal function is reconfigurable, the default state is shown in plain text, while the alternate function is shown in italics. All pins are three-stated during and immediately after reset, with the exception of the external memory interface, asynchronous and synchronous memory control, and the buffered XTAL output pin (CLKBUF). On the external memory interface, the control and address lines are driven high, with the exception of CLKOUT, which toggles at the system clock rate. All I/O signals have their input buffers disabled with the exception of the signals noted in the data sheet that need pull-ups or pull downs if unused. Table 9.

Consult version 2.1 of the I2C specification for the proper resistor value. It is strongly advised to use the available IBIS models to ensure that a given board design meets overshoot/undershoot and signal integrity requirements. If no IBIS simulation is performed, it is strongly recommended to add series resistor terminations for all Driver Types A, C and D. The termination resistors should be placed near the processor to reduce transients and improve signal integrity. The resistance value, typically 33 Ω or 47 Ω, should be chosen to match the average board trace impedance. Additionally, adding a parallel termination to CLKOUT may prove useful in further enhancing signal integrity. Be sure to verify overshoot/undershoot and signal integrity specifications on actual hardware.

When driven low, the PF15 signal can be used to wake up the processor from the hibernate state, either in normal GPIO mode or in Ethernet mode as PHYINT. If the pin/ball is used for wake up, enable the feature with the PHYWE bit in the VR_CTL register, and pull-up the signal with a resistor. 3 Boot host wait is a GPIO signal toggled by the boot kernel. The mandatory external pull-up/pull-down resistor defines the signal polarity. 4 A pull-up resistor is required for the boot from external SPI EEPROM or flash (BMODE = 0x3). Rev.

Must remain powered (even if the associated function is not used). 3 VDDEXT is the supply to the GPIO. 4 If not used, power with VDDEXT. 5 Pins/balls that use VDDMEM are DATA15–0, ADDR19–1, ABE1–0, ARE, AWE, AMS1–0, SA10, SWE, SCAS, CLKOUT, SRAS, SMS, SCKE. These pins/balls are not tolerant to voltages higher than VDDMEM. When using any of the asynchronous memory signals AMS3–2, ARDY, or AOE VDDMEM and VDDEXT must be shorted externally because these signals are multiplexed with GPIO. 6 The VDDOTP voltage for writes must only be applied when programming OTP memory. There is a finite amount of cumulative time that this voltage may be applied (dependent on voltage and junction temperature) over the lifetime of the part. Please see Table 17 on Page 26 for details. 7 Bidirectional pins/balls (PF15–0, PG15–0, PH7–0) and input pins/balls (RTXI, TCK, TDI, TMS, TRST, CLKIN, RESET, NMI, and BMODE2–0) of the ADSPBF512/BF514/BF516/BF518(F) are 3.3 V tolerant (always accept up to 3.6 V maximum VIH). Voltage compliance (on outputs, VOH) is limited by the VDDEXT supply voltage. 8 Parameter value applies to all input and bidirectional pins/balls except SDA and SCL. 9 The VIHTWI min and max value vary with the selection in the TWI_DT field of the NONGPIO_DRIVE register. See VBUSTWI min and max values in Table 11. 10 SDA and SCL are pulled up to VBUSTWI. See Table 10. Rev. PrE | Page 23 of 62 | March 2009 ADSP-BF512/BF514/BF516/BF518(F) Table 10 shows settings for TWI_DT in the NONGPIO_DRIVE register. Set this register prior to using the TWI port. Table 10.

Charged devices and circuit boards can discharge without detection. Although this product features patented or proprietary protection circuitry, damage may occur on devices subjected to high energy ESD. Therefore, proper ESD precautions should be taken to avoid performance degradation or loss of functionality. Applies to all signal pins/balls with the exception of CLKIN, XTAL, VROUT. When programming OTP memory on the ADSPBF512/BF514/BF516/BF518(F) processor, the VPPOTP pin/ball must be set to the write value specified in the Operating Conditions on Page 23. There is a finite amount of cumulative time that the write voltage may be applied (dependent on voltage and junction temperature) to VPPOTP over the lifetime of the part.

Drive Current F (High VDDEXT) POWER DISSIPATION Total power dissipation has two components: one due to internal circuitry (PINT) and one due to the switching of external output drivers (PEXT). See the ADSP-BF51x Blackfin Processor Hardware Reference Manual for definitions of the various operating modes and for instructions on how to minimize system power. Many operating conditions can affect power dissipation. System designers should refer to (EE-TBD) Estimating Power for ADSP-BF512/BF514/BF516/BF518(F) Blackfin Processors on the Analog Devices website (www.analog.com)—use site search on “EE-TBD.” That document provides detailed information for optimizing your design for lowest power. Figure 46. Output Enable/Disable The time tENA_MEASURED is the interval, from when the reference signal switches, to when the output voltage reaches VTRIP(high) or VTRIP(low). VTRIP(high) is 2.0 V and VTRIP(low) is 1.0 V for VDDEXT/VDDMEM (nominal) = 2.5 V/3.3 V. Time tTRIP is the interval from when the output starts driving to when the output reaches the VTRIP(high) or VTRIP(low) trip voltage. Time tENA is calculated as shown in the equation: t ENA = t ENA_MEASURED – t TRIP If multiple signals (such as the data bus) are enabled, the measurement value is that of the first signal to start driving. Output Disable Time Measurement Output signals are considered to be disabled when they stop driving, go into a high impedance state, and start to decay from their output high or low voltage. The output disable time tDIS is the difference between tDIS_MEASURED and tDECAY as shown on the left side of Figure 46. t DIS = t DIS_MEASURED – t DECAY The time for the voltage on the bus to decay by ΔV is dependent on the capacitive load CL and the load current IL. This decay time can be approximated by the equation: t DECAY = ( C L ΔV ) ⁄ I L TEST CONDITIONS All timing parameters appearing in this data sheet were measured under the conditions described in this section. Figure 45 shows the measurement point for AC measurements (except output enable/disable). The measurement point VMEAS is VDDEXT/2 or VDDMEM/2 for VDDEXT/VDDMEM (nominal) = 2.5 V/3.3 V. INPUT OR OUTPUT V MEA S VMEA S Figure 45. Voltage Reference Levels for AC Measurements (Except Output Enable/Disable) The time tDECAY is calculated with test loads CL and IL, and with ΔV equal to 0.5 V for VDDEXT/VDDMEM (nominal) = 2.5 V/3.3 V. The time tDIS_MEASURED is the interval from when the reference signal switches, to when the output voltage decays ΔV from the measured output high or output low voltage. Output Enable Time Measurement Output signals are considered to be enabled when they have made a transition from a high impedance state to the point when they start driving. Example System Hold Time Calculation To determine the data output hold time in a particular system, first calculate tDECAY using the equation given above.

CL is the total bus capacitance (per data line), and IL is the total leakage or three-state current (per data line). The hold time will be tDECAY plus the various output disable times as specified in the Timing Specifications on Page 27 (for example tDSDAT for an SDRAM write cycle as shown in SDRAM Interface Timing on Page 30). Preliminary Technical Data TBD Capacitive Loading Output delays and holds are based on standard capacitive loads: 30 pF on all pins/balls (see Figure 47). VLOAD is 1.5 V for VDDEXT (nominal) = 2.5 V/3.3 V. Figure 48 on Page 52 through Figure 55 on Page 53 show how output rise time varies with capacitance. The delay and hold specifications given should be derated by a factor derived from these figures. The graphs in these figures may not be linear outside the ranges shown. Figure 48.
