Architectural Overview Introducing the CY8C38 family of ultra low-power, flash Programmable System-on-Chip (PSoC®) devices, part of a scalable 8-bit PSoC 3 and 32-bit PSoC 5 platform. The CY8C38 family provides configurable blocks of analog, digital, and interconnect circuitry around a CPU subsystem. The combination of a CPU with a flexible analog subsystem, digital subsystem, routing, and I/O enables a high level of integration in a wide variety of consumer, industrial, and medical applications.

AH PSoC’s digital subsystem provides half of its unique configurability. It connects a digital signal from any peripheral to any pin through the digital system interconnect (DSI). It also provides functional flexibility through an array of small, fast, low-power UDBs. PSoC Creator provides a library of prebuilt and tested standard digital peripherals (UART, SPI, LIN, PRS, CRC, timer, counter, PWM, AND, OR, and so on) that are mapped to the UDB array. You can also easily create a digital circuit using boolean primitives by means of graphical design entry. Each UDB contains programmable array logic (PAL)/programmable logic device (PLD) functionality, together with a small state machine engine to support a wide variety of peripherals. In addition to the flexibility of the UDB array, PSoC also provides configurable digital blocks targeted at specific functions. For the CY8C38 family these blocks can include four 16-bit timers, counters, and PWM blocks; I2C slave, master, and multimaster; FS USB; and Full CAN 2.0b. Page 4 of 140 PSoC® 3: CY8C38 Family Datasheet For more details on the peripherals see the “Example Peripherals” section on page 44 of this data sheet. For information on UDBs, DSI, and other digital blocks, see the “Digital Subsystem” section on page 44 of this data sheet. PSoC’s analog subsystem is the second half of its unique configurability. All analog performance is based on a highly accurate absolute voltage reference with less than 0.1-percent error over temperature and voltage. The configurable analog subsystem includes:  Analog muxes  Comparators  Voltage references  Analog-to-digital converter (ADC)  Digital-to-analog converters (DACs)  Digital filter block (DFB) All GPIO pins can route analog signals into and out of the device using the internal analog bus. This allows the device to interface up to 62 discrete analog signals. The heart of the analog subsystem is a fast, accurate, configurable delta-sigma ADC with these features:  Less than 100 µV offset  A gain error of 0.2 percent  INL less than ±2 LSB  DNL less than ±1 LSB  SINAD better than 84 dB in 16-bit mode This converter addresses a wide variety of precision analog applications, including some of the most demanding sensors. The output of the ADC can optionally feed the programmable DFB through the DMA without CPU intervention. You can configure the DFB to perform IIR and FIR digital filters and several user-defined custom functions. The DFB can implement filters with up to 64 taps. It can perform a 48-bit multiply-accumulate (MAC) operation in one clock cycle. Four high-speed voltage or current DACs support 8-bit output signals at an update rate of up to 8 Msps. They can be routed out of any GPIO pin. You can create higher resolution voltage PWM DAC outputs using the UDB array. This can be used to create a pulse width modulated (PWM) DAC of up to 10 bits, at up to 48 kHz. The digital DACs in each UDB support PWM, PRS, or delta-sigma algorithms with programmable widths. In addition to the ADC, DACs, and DFB, the analog subsystem provides multiple:  Uncommitted opamps  Configurable switched capacitor/continuous time (SC/CT) blocks. These support:  Transimpedance amplifiers  Programmable gain amplifiers  Mixers  Other similar analog components See the “Analog Subsystem” section on page 56 of this data sheet for more details. PSoC’s 8051 CPU subsystem is built around a single cycle pipelined 8051 8-bit processor running at up to 67 MHz. The CPU subsystem includes a programmable nested vector interrupt controller, DMA controller, and RAM. PSoC’s nested vector interrupt controller provides low latency by allowing the CPU to vector directly to the first address of the interrupt service routine, bypassing the jump instruction required by other architectures. The DMA controller enables peripherals to exchange data without CPU involvement. This allows the CPU to run slower (saving power) or use those CPU cycles to improve the performance of firmware algorithms. The single cycle 8051 CPU runs ten times faster than a standard 8051 processor. The processor speed itself is configurable, allowing you to tune active power consumption for specific applications. PSoC’s nonvolatile subsystem consists of flash, byte-writeable EEPROM, and nonvolatile configuration options. It provides up to 64 KB of on-chip flash. The CPU can reprogram individual blocks of flash, enabling bootloaders. You can enable an error correcting code (ECC) for high reliability applications. A powerful and flexible protection model secures the user's sensitive information, allowing selective memory block locking for read and write protection. Up to 2 KB of byte-writeable EEPROM is available on-chip to store application data. Additionally, selected configuration options such as boot speed and pin drive mode are stored in nonvolatile memory. This allows settings to activate immediately after POR. The three types of PSoC I/O are extremely flexible. All I/Os have many drive modes that are set at POR. PSoC also provides up to four I/O voltage domains through the VDDIO pins. Every GPIO has analog I/O, LCD drive[3], CapSense[4], flexible interrupt generation, slew rate control, and digital I/O capability. The SIOs on PSoC allow VOH to be set independently of Vddio when used as outputs. When SIOs are in input mode they are high impedance. This is true even when the device is not powered or when the pin voltage goes above the supply voltage. This makes the SIO ideally suited for use on an I2C bus where the PSoC may not be powered when other devices on the bus are. The SIO pins also have high current sink capability for applications such as LED drives. The programmable input threshold feature of the SIO can be used to make the SIO function as a general purpose analog comparator. For devices with Full-Speed USB the USB physical interface is also provided (USBIO). When not using USB these pins may also be used for limited digital functionality and device programming. All of the features of the PSoC I/Os are covered in detail in the “I/O System and Routing” section on page 37 of this data sheet. The PSoC device incorporates flexible internal clock generators, designed for high stability and factory trimmed for high accuracy. The internal main oscillator (IMO) is the clock base for the system, and has 1-percent accuracy at 3 MHz. The IMO can be configured to run from 3 MHz up to 62 MHz. Multiple clock derivatives can be generated from the main clock frequency to meet application needs. The device provides a PLL to generate clock frequencies up to 67 MHz from the IMO, external crystal, or external reference clock. Notes 3. This feature on select devices only. See Ordering Information on page 123 for details. 4. GPIOs with opamp outputs are not recommended for use with CapSense. Document Number: 001-11729 Rev. AH Page 5 of 140 PSoC® 3: CY8C38 Family Datasheet It also contains a separate, very low-power internal low-speed oscillator (ILO) for the sleep and watchdog timers. A 32.768-kHz external watch crystal is also supported for use in real-time clock (RTC) applications. The clocks, together with programmable clock dividers, provide the flexibility to integrate most timing requirements. The CY8C38 family supports a wide supply operating range from 1.71 V to 5.5 V. This allows operation from regulated supplies such as 1.8 V ± 5%, 2.5 V ±10%, 3.3 V ± 10%, or 5.0 V ± 10%, or directly from a wide range of battery types. In addition, it provides an integrated high efficiency synchronous boost converter that can power the device from supply voltages as low as 0.5 V. This enables the device to be powered directly from a single battery or solar cell. In addition, you can use the boost converter to generate other voltages required by the device, such as a 3.3-V supply for LCD glass drive. The boost’s output is available on the VBOOST pin, allowing other devices in the application to be powered from the PSoC. PSoC supports a wide range of low-power modes. These include a 200-nA hibernate mode with RAM retention and a 1-µA sleep mode with RTC. In the second mode, the optional 32.768-kHz watch crystal runs continuously and maintains an accurate RTC. Power to all major functional blocks, including the programmable digital and analog peripherals, can be controlled independently by firmware. This allows low-power background processing when some peripherals are not in use. This, in turn, provides a total device current of only 1.2 mA when the CPU is running at 6 MHz, or 0.8 mA running at 3 MHz. The details of the PSoC power modes are covered in the “Power System” section on page 31 of this data sheet. PSoC uses JTAG (4-wire) or SWD (2-wire) interfaces for programming, debug, and test. The 1-wire SWV may also be used for ‘printf’ style debugging. By combining SWD and SWV, you can implement a full debugging interface with just three pins. Using these standard interfaces you can debug or program the PSoC with a variety of hardware solutions from Cypress or third party vendors. PSoC supports on-chip break points and 4-KB instruction and data race memory for debug. Details of the programming, test, and debugging interfaces are discussed in the “Programming, Debug Interfaces, Resources” section on page 65 of this data sheet. 2. Pinouts Each VDDIO pin powers a specific set of I/O pins. (The USBIOs are powered from VDDD.) Using the VDDIO pins, a single PSoC can support multiple voltage levels, reducing the need for off-chip level shifters. The black lines drawn on the pinout diagrams in Figure 2-3 through Figure 2-6, as well as Table 2-1, show the pins that are powered by each VDDIO. Each VDDIO may source up to 100 mA total to its associated I/O pins, as shown in Figure 2-1. Figure 2-1. VDDIO Current Limit IDDIO X mA VDDIO X I/O Pins PSoC Conversely, for the 100-pin and 68-pin devices, the set of I/O pins associated with any VDDIO may sink up to 100 mA total, as shown in Figure 2-2. Figure 2-2. I/O Pins Current Limit Ipins VDDIO X mA I/O Pins PSoC VSSD For the 48-pin devices, the set of I/O pins associated with VDDIO0 plus VDDIO2 may sink up to 100 mA total. The set of I/O pins associated with VDDIO1 plus VDDIO3 may sink up to a total of 100 mA. Document Number: 001-11729 Rev.

CPU 4.1 8051 CPU The CY8C38 devices use a single cycle 8051 CPU, which is fully compatible with the original MCS-51 instruction set. The CY8C38 family uses a pipelined RISC architecture, which executes most instructions in 1 to 2 cycles to provide peak performance of up to 33 MIPS with an average of 2 cycles per instruction. The single cycle 8051 CPU runs ten times faster than a standard 8051 processor. The 8051 CPU subsystem includes these features:  Single cycle 8051 CPU  Up to 64 KB of flash memory, up to 2 KB of EEPROM, and up to 8 KB of SRAM  512-byte instruction cache between CPU and flash  Programmable nested vector interrupt controller  DMA controller  Peripheral HUB (PHUB)  External memory interface (EMIF) 4.2 Addressing Modes The following addressing modes are supported by the 8051:  Direct Addressing: The operand is specified by a direct 8-bit address field. Only the internal RAM and the SFRs can be accessed using this mode.  Indirect Addressing: The instruction specifies the register which contains the address of the operand. The registers R0 or R1 are used to specify the 8-bit address, while the data pointer (DPTR) register is used to specify the 16-bit address.  Register Addressing: Certain instructions access one of the registers (R0 to R7) in the specified register bank. These instructions are more efficient because there is no need for an address field.  Register Specific Instructions: Some instructions are specific to certain registers. For example, some instructions always act on the accumulator. In this case, there is no need to specify the operand.  Immediate Constants: Some instructions carry the value of the constants directly instead of an address.  Indexed Addressing: This type of addressing can be used only for a read of the program memory. This mode uses the Data Pointer as the base and the accumulator value as an offset to read a program memory.  Bit Addressing: In this mode, the operand is one of 256 bits.

AH Page 13 of 140 PSoC® 3: CY8C38 Family Datasheet 4.3 Instruction Set  Data transfer instructions The 8051 instruction set is highly optimized for 8-bit handling and Boolean operations. The types of instructions supported include:  Boolean instructions  Program branching instructions  Arithmetic instructions  Logical instructions 4.3.1 Instruction Set Summary 4.3.1.1 Arithmetic Instructions Arithmetic instructions support the direct, indirect, register, immediate constant, and register-specific instructions. Arithmetic modes are used for addition, subtraction, multiplication, division, increment, and decrement operations. Table 4-1 lists the different arithmetic instructions. Table 4-1.

AH Page 14 of 140 PSoC® 3: CY8C38 Family Datasheet 4.3.1.2 Logical Instructions The logical instructions perform Boolean operations such as AND, OR, XOR on bytes, rotate of accumulator contents, and swap of nibbles in an accumulator. The Boolean operations on the bytes are performed on the bit-by-bit basis. Table 4-2 shows the list of logical instructions and their description. Table 4-2.

The core RAM transfer includes transfer between any two core RAM locations or SFRs. These instructions can use direct, indirect, register, and immediate addressing. The xdata RAM transfer includes only the transfer between the accumulator and the xdata RAM location. It can use only indirect addressing. The lookup tables involve nothing but the read of program memory using the Indexed Document Number: 001-11729 Rev. AH addressing mode. Table 4-3 lists the various data transfer instructions available. 4.3.1.4 Boolean Instructions The 8051 core has a separate bit-addressable memory location. It has 128 bits of bit addressable RAM and a set of SFRs that are bit addressable. The instruction set includes the whole menu of bit operations such as move, set, clear, toggle, OR, and AND instructions and the conditional jump instructions.

AH Page 17 of 140 PSoC® 3: CY8C38 Family Datasheet 4.4 DMA and PHUB  Transactions can be stalled or canceled The PHUB and the DMA controller are responsible for data transfer between the CPU and peripherals, and also data transfers between peripherals. The PHUB and DMA also control device configuration during boot. The PHUB consists of:  Supports transaction size of infinite or 1 to 64 KB  A central hub that includes the DMA controller, arbiter, and router  Multiple spokes that radiate outward from the hub to most peripherals There are two PHUB masters: the CPU and the DMA controller. Both masters may initiate transactions on the bus. The DMA channels can handle peripheral communication without CPU intervention. The arbiter in the central hub determines which DMA channel is the highest priority if there are multiple requests. 4.4.1 PHUB Features  CPU and DMA controller are both bus masters to the PHUB  Eight multi-layer AHB bus parallel access paths (spokes) for peripheral access  Simultaneous CPU and DMA access to peripherals located on different spokes  Simultaneous DMA source and destination burst transactions on different spokes  Supports 8-, 16-, 24-, and 32-bit addressing and data Table 4-6. PHUB Spokes and Peripherals PHUB Spokes Peripherals 0 SRAM 1 IOs, PICU, EMIF 2 PHUB local configuration, Power manager, Clocks, IC, SWV, EEPROM, Flash programming interface  TDs may be nested and/or chained for complex transactions 4.4.3 Priority Levels The CPU always has higher priority than the DMA controller when their accesses require the same bus resources. Due to the system architecture, the CPU can never starve the DMA. DMA channels of higher priority (lower priority number) may interrupt current DMA transfers. In the case of an interrupt, the current transfer is allowed to complete its current transaction. To ensure latency limits when multiple DMA accesses are requested simultaneously, a fairness algorithm guarantees an interleaved minimum percentage of bus bandwidth for priority levels 2 through 7. Priority levels 0 and 1 do not take part in the fairness algorithm and may use 100 percent of the bus bandwidth. If a tie occurs on two DMA requests of the same priority level, a simple round robin method is used to evenly share the allocated bandwidth. The round robin allocation can be disabled for each DMA channel, allowing it to always be at the head of the line. Priority levels 2 to 7 are guaranteed the minimum bus bandwidth shown in Table 4-7 after the CPU and DMA priority levels 0 and 1 have satisfied their requirements. Table 4-7. Priority Levels Priority Level % Bus Bandwidth 0 100.0 1 100.0 2 50.0 3 25.0 4 12.5 5 6.2 6 3.1 7 1.5 3 Analog interface and trim, Decimator 4 USB, CAN, I2C, Timers, Counters, and PWMs 5 DFB When the fairness algorithm is disabled, DMA access is granted based solely on the priority level; no bus bandwidth guarantees are made. 6 UDBs group 1 7 UDBs group 2 4.4.4 Transaction Modes Supported 4.4.2 DMA Features  24 DMA channels  Each channel has one or more transaction descriptors (TD) to configure channel behavior. Up to 128 total TDs can be defined  TDs can be dynamically updated  Eight levels of priority per channel  Any digitally routable signal, the CPU, or another DMA channel, The flexible configuration of each DMA channel and the ability to chain multiple channels allow the creation of both simple and complex use cases. General use cases include, but are not limited to: 4.4.4.1 Simple DMA In a simple DMA case, a single TD transfers data between a source and sink (peripherals or memory location). The basic timing diagrams of DMA read and write cycles are shown in Figure 4-1. For more description on other transfer modes, refer to the Technical Reference Manual. can trigger a transaction  Each channel can generate up to two interrupts per transfer Document Number: 001-11729 Rev.

This is done with a single TD that chains to itself. 4.4.4.3 Ping Pong DMA A ping pong DMA case uses double buffering to allow one buffer to be filled by one client while another client is consuming the data previously received in the other buffer. In its simplest form, this is done by chaining two TDs together so that each TD calls the opposite TD when complete. phase TD(s) finish, a status phase TD can be invoked that reads some memory mapped status information from the peripheral and copies it to a location in system memory specified by the CPU for later inspection. Multiple sets of configuration, data, and status phase ‘subchains’ can be strung together to create larger chains that transmit multiple packets in this way. A similar concept exists in the opposite direction to receive the packets. 4.4.4.7 Nested DMA Circular DMA is similar to ping pong DMA except it contains more than two buffers. In this case there are multiple TDs; after the last TD is complete it chains back to the first TD. One TD may modify another TD, as the TD configuration space is memory mapped similar to any other peripheral. For example, a first TD loads a second TD’s configuration and then calls the second TD. The second TD moves data as required by the application. When complete, the second TD calls the first TD, which again updates the second TD’s configuration. This process repeats as often as necessary. 4.4.4.5 Scatter Gather DMA 4.5 Interrupt Controller In the case of scatter gather DMA, there are multiple noncontiguous sources or destinations that are required to effectively carry out an overall DMA transaction. For example, a packet may need to be transmitted off of the device and the packet elements, including the header, payload, and trailer, exist in various noncontiguous locations in memory. Scatter gather DMA allows the segments to be concatenated together by using multiple TDs in a chain. The chain gathers the data from the multiple locations. A similar concept applies for the reception of data onto the device. Certain parts of the received data may need to be scattered to various locations in memory for software processing convenience. Each TD in the chain specifies the location for each discrete element in the chain. The interrupt controller provides a mechanism for hardware resources to change program execution to a new address, independent of the current task being executed by the main code. The interrupt controller provides enhanced features not found on original 8051 interrupt controllers: 4.4.4.4 Circular DMA 4.4.4.6 Packet Queuing DMA Packet queuing DMA is similar to scatter gather DMA but specifically refers to packet protocols. With these protocols, there may be separate configuration, data, and status phases associated with sending or receiving a packet. For instance, to transmit a packet, a memory mapped configuration register can be written inside a peripheral, specifying the overall length of the ensuing data phase. The CPU can set up this configuration information anywhere in system memory and copy it with a simple TD to the peripheral. After the configuration phase, a data phase TD (or a series of data phase TDs) can begin (potentially using scatter gather). When the data Document Number: 001-11729 Rev.

Code execution then jumps to the program address provided by the vector. After the ISR is completed, a RETI instruction is executed and returns execution to the instruction following the previously interrupted instruction. To do this the RETI instruction pops the program counter from the stack. If the same priority level is assigned to two or more interrupts, the interrupt with the lower vector number is executed first. Each interrupt vector may choose from three interrupt sources: Fixed Function, DMA, and UDB. The fixed function interrupts are Document Number: 001-11729 Rev. AH Lowest Priority direct connections to the most common interrupt sources and provide the lowest resource cost connection. The DMA interrupt sources provide direct connections to the two DMA interrupt sources provided per DMA channel. The third interrupt source for vectors is from the UDB digital routing array. This allows any digital signal available to the UDB array to be used as an interrupt source. Fixed function interrupts and all interrupt sources may be routed to any interrupt vector using the UDB interrupt source connections. Page 21 of 140 PSoC® 3: CY8C38 Family Datasheet Table 4-8.

AH Page 22 of 140 PSoC® 3: CY8C38 Family Datasheet 5. Memory 5.1 Static RAM CY8C38 SRAM is used for temporary data storage. Up to 8 KB of SRAM is provided and can be accessed by the 8051 or the DMA controller. See Memory Map on page 26. Simultaneous access of SRAM by the 8051 and the DMA controller is possible if different 4-KB blocks are accessed. 5.2 Flash Program Memory Flash memory in PSoC devices provides nonvolatile storage for user firmware, user configuration data, bulk data storage, and optional ECC data. The main flash memory area contains up to 64 KB of user program space. Up to an additional 8 KB of flash space is available for ECC. If ECC is not used this space can store device configuration data and bulk user data. User code may not be run out of the ECC flash memory section. ECC can correct one bit error and detect two bit errors per 8 bytes of firmware memory; an interrupt can be generated when an error is detected. The CPU reads instructions located in flash through a cache controller. This improves instruction execution rate and reduces system power consumption by requiring less frequent flash access. The cache has 8 lines at 64 bytes per line for a total of 512 bytes. It is fully associative, automatically controls flash power, and can be enabled or disabled. If ECC is enabled, the cache controller also performs error checking and correction, and interrupt generation. Flash programming is performed through a special interface and preempts code execution out of flash. The flash programming interface performs flash erasing, programming and setting code protection levels. Flash in-system serial programming (ISSP), typically used for production programming, is possible through both the SWD and JTAG interfaces. In-system programming, typically used for bootloaders, is also possible using serial interfaces such as I2C, USB, UART, and SPI, or any communications protocol. 5.3 Flash Security All PSoC devices include a flexible flash-protection model that prevents access and visibility to on-chip flash memory. This prevents duplication or reverse engineering of proprietary code. Flash memory is organized in blocks, where each block contains 256 bytes of program or data and 32 bytes of ECC or configuration data. A total of up to 256 blocks is provided on 64-KB flash devices. The device offers the ability to assign one of four protection levels to each row of flash. Table 5-1 lists the protection modes available. Flash protection levels can only be changed by performing a complete flash erase. The Full Protection and Field Upgrade settings disable external access (through a debugging tool such as PSoC Creator, for example). If your application requires code update through a bootloader, then use the Field Upgrade setting. Use the Unprotected setting only when no security is needed in your application. The PSoC device also offers an advanced security feature called Device Security which permanently disables all test, programming, and debug ports, protecting your application from external access (see the “Device Security” section on page 68). For more information Document Number: 001-11729 Rev. AH about how to take full advantage of the security features in PSoC, see the PSoC 3 TRM. Table 5-1. Flash Protection Protection Setting Allowed Not Allowed Unprotected External read and write – + internal read and write Factory Upgrade External write + internal read and write External read Field Upgrade Internal read and write External read and write Full Protection Internal read External read and write + internal write Disclaimer Note the following details of the flash code protection features on Cypress devices. Cypress products meet the specifications contained in their particular Cypress data sheets. Cypress believes that its family of products is one of the most secure families of its kind on the market today, regardless of how they are used. There may be methods, unknown to Cypress, that can breach the code protection features. Any of these methods, to our knowledge, would be dishonest and possibly illegal. Neither Cypress nor any other semiconductor manufacturer can guarantee the security of their code. Code protection does not mean that we are guaranteeing the product as ‘unbreakable’. Cypress is willing to work with the customer who is concerned about the integrity of their code. Code protection is constantly evolving. We at Cypress are committed to continuously improving the code protection features of our products. 5.4 EEPROM PSoC EEPROM memory is a byte-addressable nonvolatile memory. The CY8C38 has up to 2 KB of EEPROM memory to store user data. Reads from EEPROM are random access at the byte level. Reads are done directly; writes are done by sending write commands to an EEPROM programming interface. CPU code execution can continue from flash during EEPROM writes. EEPROM is erasable and writeable at the row level. The EEPROM is divided into 128 rows of 16 bytes each. The factory default values of all EEPROM bytes are 0. Because the EEPROM is mapped to the 8051 xdata space, the CPU can not execute out of EEPROM. There is no ECC hardware associated with EEPROM. If ECC is required it must be handled in firmware. It can take as much as 20 milliseconds to write to EEPROM or flash. During this time the device should not be reset, or unexpected changes may be made to portions of EEPROM or flash. Reset sources (see Section 6.3.1) include XRES pin, software reset, and watchdog; care should be taken to make sure that these are not inadvertently activated. In addition, the low voltage detect circuits should be configured to generate an interrupt instead of a reset. Page 23 of 140 PSoC® 3: CY8C38 Family Datasheet 5.5 Nonvolatile Latches (NVLs) PSoC has a 4-byte array of nonvolatile latches (NVLs) that are used to configure the device at reset. The NVL register map is shown in Table 5-2. Table 5-2.

Although PSoC Creator provides support for modifying the device configuration NVLs, the number of NVL erase / write cycles is limited – see “Nonvolatile Latches (NVL))” on page 113.

The connection allows read and write accesses to external memories. The EMIF operates in conjunction with UDBs, I/O ports, and other hardware to generate external memory address and control signals. At 33 MHz, each memory access cycle takes four bus clock cycles. Figure 5-1 is the EMIF block diagram. The EMIF supports synchronous and asynchronous memories. The CY8C38 supports only one type of external memory device at a time. External memory can be accessed through the 8051 xdata space; up to 24 address bits can be used. See “xdata Space” section on page 27. The memory can be 8 or 16 bits wide. Figure 5-1.

With direct addressing mode, the upper 128 bytes map to the SFRs. With indirect addressing mode, the upper 128 bytes map to RAM. Stack operations use indirect addressing; the 8051 stack space is 256 bytes. See the “Addressing Modes” section on page 13. 5.7.3 SFRs The SFR space provides access to frequently accessed registers.

The data pointer select SFR, DPS, selects which data pointer register, DPTR0 or DPTR1, is used for the following instructions: The 8051 xdata space is 24-bit, or 16 MB in size. The majority of this space is not ‘external’—it is used by on-chip components. See Table 5-5. External, that is, off-chip, memory can be accessed using the EMIF. See External Memory Interface on page 25.  MOVX @DPTR, A  MOVX A, @DPTR  MOVC A, @A+DPTR  JMP @A+DPTR  INC DPTR  MOV DPTR, #data16 The extended data pointer SFRs, DPX0, DPX1, MXAX, and P2AX, hold the most significant parts of memory addresses during access to the xdata space. These SFRs are used only with the MOVX instructions. During a MOVX instruction using the DPTR0/DPTR1 register, the most significant byte of the address is always equal to the contents of DPX0/DPX1. During a MOVX instruction using the R0 or R1 register, the most significant byte of the address is always equal to the contents of MXAX, and the next most significant byte is always equal to the contents of P2AX. 5.7.5 I/O Port SFRs The I/O ports provide digital input sensing, output drive, pin interrupts, connectivity for analog inputs and outputs, LCD, and access to peripherals through the DSI. Full information on I/O ports is found in I/O System and Routing on page 37. I/O ports are linked to the CPU through the PHUB and are also available in the SFRs. Using the SFRs allows faster access to a limited set of I/O port registers, while using the PHUB allows boot configuration and access to all I/O port registers. Table 5-5.

If a SFRPRTxSEL[y] bit is high, the corresponding SFRPRTxDR[y] bit sets the output state for that pin. If a SFRPRTxSEL[y] bit is low, the corresponding PRTxDR[y] bit sets the output state of the pin (where y varies from 0 to 7).  The SFRPRTxPS is a read only register that contains pin state values of the port pins.

System Integration Key features of the clocking system include:  Seven general purpose clock sources 6.1 Clocking System The clocking system generates, divides, and distributes clocks throughout the PSoC system. For the majority of systems, no external crystal is required. The IMO and PLL together can generate up to a 66 MHz clock, accurate to ±1 percent over voltage and temperature. Additional internal and external clock sources allow each design to optimize accuracy, power, and cost. Any of the clock sources can be used to generate other clock frequencies in the 16-bit clock dividers and UDBs for anything the user wants, for example a UART baud rate generator. Clock generation and distribution is automatically configured through the PSoC Creator IDE graphical interface. This is based on the complete system’s requirements. It greatly speeds the design process. PSoC Creator allows you to build clocking systems with minimal input. You can specify desired clock frequencies and accuracies, and the software locates or builds a clock that meets the required specifications. This is possible because of the programmability inherent in PSoC. 3- to 62-MHz IMO, ±1% at 3 MHz 4- to 25-MHz external crystal oscillator (MHzECO)  Clock doubler provides a doubled clock frequency output for the USB block, see USB Clock Domain on page 30.  DSI signal from an external I/O pin or other logic  24- to 67-MHz fractional PLL sourced from IMO, MHzECO, or DSI  1-kHz, 33-kHz, 100-kHz ILO for WDT and sleep timer  32.768-kHz external crystal oscillator (kHzECO) for RTC  IMO has a USB mode that auto locks to the USB bus clock requiring no external crystal for USB (USB equipped parts only)    Independently sourced clock in all clock dividers  Eight 16-bit clock dividers for the digital system  Four 16-bit clock dividers for the analog system  Dedicated 16-bit divider for the bus clock  Dedicated 4-bit divider for the CPU clock  Automatic clock configuration in PSoC Creator Table 6-1.

AH Bus Clock Page 28 of 140 PSoC® 3: CY8C38 Family Datasheet 6.1.1 Internal Oscillators Figure 6-1 shows that there are two internal oscillators. They can be routed directly or divided. The direct routes may not have a 50% duty cycle. Divided clocks have a 50% duty cycle. 6.1.1.1 Internal Main Oscillator In most designs the IMO is the only clock source required, due to its ±1-percent accuracy. The IMO operates with no external components and outputs a stable clock. A factory trim for each frequency range is stored in the device. With the factory trim, tolerance varies from ±1 percent at 3 MHz, up to ±7 percent at 62 MHz. The IMO, in conjunction with the PLL, allows generation of other clocks up to the device's maximum frequency (see PLL). The IMO provides clock outputs at 3, 6, 12, 24, 48, and 62 MHz. 6.1.1.2 Clock Doubler The clock doubler outputs a clock at twice the frequency of the input clock. The doubler works at input frequency of 24 MHz, providing 48 MHz for the USB. It can be configured to use a clock from the IMO, MHzECO, or the DSI (external pin). 6.1.1.3 PLL The PLL allows low-frequency, high-accuracy clocks to be multiplied to higher frequencies. This is a trade off between higher clock frequency and accuracy and, higher power consumption and increased startup time. The PLL block provides a mechanism for generating clock frequencies based upon a variety of input sources. The PLL outputs clock frequencies in the range of 24 to 67 MHz. Its input and feedback dividers supply 4032 discrete ratios to create almost any desired clock frequency. The accuracy of the PLL output depends on the accuracy of the PLL input source. The most common PLL use is to multiply the IMO clock at 3 MHz, where it is most accurate, to generate the other clocks up to the device’s maximum frequency. The PLL achieves phase lock within 250 µs (verified by bit setting). It can be configured to use a clock from the IMO, MHzECO or DSI (external pin). The PLL clock source can be used until lock is complete and signaled with a lock bit. The lock signal can be routed through the DSI to generate an interrupt. Disable the PLL before entering low-power modes. 6.1.1.4 Internal Low-Speed Oscillator The ILO provides clock frequencies for low-power consumption, including the watchdog timer, and sleep timer. The ILO generates up to three different clocks: 1 kHz, 33 kHz, and 100 kHz. The 1-kHz clock (CLK1K) is typically used for a background ‘heartbeat’ timer. This clock inherently lends itself to low-power supervisory operations such as the watchdog timer and long sleep intervals using the central timewheel (CTW). The central timewheel is a 1-kHz, free running, 13-bit counter clocked by the ILO. The central timewheel is always enabled, except in hibernate mode and when the CPU is stopped during debug on chip mode. It can be used to generate periodic interrupts for timing purposes or to wake the system from a low-power mode. Firmware can reset the central timewheel. Systems that require accurate timing should use the RTC capability instead of the central timewheel. Document Number: 001-11729 Rev. AH The 100-kHz clock (CLK100K) can be used as a low power master clock. It can also generate time intervals using the fast timewheel. The fast timewheel is a 5-bit counter, clocked by the 100-kHz clock. It features programmable settings and automatically resets when the terminal count is reached. An optional interrupt can be generated each time the terminal count is reached. This enables flexible, periodic interrupts of the CPU at a higher rate than is allowed using the central timewheel. The 33-kHz clock (CLK33K) comes from a divide-by-3 operation on CLK100K. This output can be used as a reduced accuracy version of the 32.768-kHz ECO clock with no need for a crystal. 6.1.2 External Oscillators Figure 6-1 shows that there are two external oscillators. They can be routed directly or divided. The direct routes may not have a 50% duty cycle. Divided clocks have a 50% duty cycle. 6.1.2.1 MHz External Crystal Oscillator The MHzECO provides high frequency, high precision clocking using an external crystal (see Figure 6-2). It supports a wide variety of crystal types, in the range of 4 to 25 MHz. When used in conjunction with the PLL, it can generate other clocks up to the device's maximum frequency (see PLL). The GPIO pins connecting to the external crystal and capacitors are fixed. MHzECO accuracy depends on the crystal chosen. Figure 6-2. MHzECO Block Diagram 4 - 25 MHz Crystal Osc Xi (Pin P15[1]) External Components XCLK_MHZ Xo (Pin P15[0]) 4 –25 MHz crystal Capacitors 6.1.2.2 32.768-kHz ECO The 32.768-kHz external crystal oscillator (32kHzECO) provides precision timing with minimal power consumption using an external 32.768-kHz watch crystal (see Figure 6-3). The 32kHzECO also connects directly to the sleep timer and provides the source for the RTC. The RTC uses a 1-second interrupt to implement the RTC functionality in firmware. The oscillator works in two distinct power modes. This allows users to trade off power consumption with noise immunity from neighboring circuits. The GPIO pins connected to the external crystal and capacitors are fixed. Page 29 of 140 PSoC® 3: CY8C38 Family Datasheet Figure 6-3. 32kHzECO Block Diagram XCLK32K 32 kHz Crystal Osc The clock distribution system generates several types of clock trees.  The master clock is used to select and supply the fastest clock in the system for general clock requirements and clock synchronization of the PSoC device.  Bus clock 16-bit divider uses the master clock to generate the bus clock used for data transfers. Bus clock is the source clock for the CPU clock divider. Xi (Pin P15[3]) External Components Xo (Pin P15[2]) 32 kHz crystal Capacitors It is recommended that the external 32.768-kHz watch crystal have a load capacitance (CL) of 6 pF or 12.5 pF. Check the crystal manufacturer's datasheet. The two external capacitors, CL1 and CL2, are typically of the same value, and their total capacitance, CL1CL2 / (CL1 + CL2), including pin and trace capacitance, should equal the crystal CL value. For more information, refer to application note AN54439: PSoC 3 and PSoC 5 External Oscillators. See also pin capacitance specifications in the “GPIO” section on page 80. 6.1.2.3 Digital System Interconnect The DSI provides routing for clocks taken from external clock oscillators connected to I/O. The oscillators can also be generated within the device in the digital system and UDBs. While the primary DSI clock input provides access to all clocking resources, up to eight other DSI clocks (internally or externally generated) may be routed directly to the eight digital clock dividers. This is only possible if there are multiple precision clock sources. 6.1.3 Clock Distribution All seven clock sources are inputs to the central clock distribution system. The distribution system is designed to create multiple high precision clocks. These clocks are customized for the design’s requirements and eliminate the common problems found with limited resolution prescalers attached to peripherals. Document Number: 001-11729 Rev. AH  Eight fully programmable 16-bit clock dividers generate digital system clocks for general use in the digital system, as configured by the design’s requirements. Digital system clocks can generate custom clocks derived from any of the seven clock sources for any purpose. Examples include baud rate generators, accurate PWM periods, and timer clocks, and many others. If more than eight digital clock dividers are required, the UDBs and fixed function timer/counter/PWMs can also generate clocks.  Four 16-bit clock dividers generate clocks for the analog system components that require clocking, such as ADC and mixers. The analog clock dividers include skew control to ensure that critical analog events do not occur simultaneously with digital switching events. This is done to reduce analog system noise. Each clock divider consists of an 8-input multiplexer, a 16-bit clock divider (divide by 2 and higher) that generates ~50 percent duty cycle clocks, master clock resynchronization logic, and deglitch logic. The outputs from each digital clock tree can be routed into the digital system interconnect and then brought back into the clock system as an input, allowing clock chaining of up to 32 bits. 6.1.4 USB Clock Domain The USB clock domain is unique in that it operates largely asynchronously from the main clock network. The USB logic contains a synchronous bus interface to the chip, while running on an asynchronous clock to process USB data. The USB logic requires a 48 MHz frequency. This frequency can be generated from different sources, including DSI clock at 48 MHz or doubled value of 24 MHz from internal oscillator, DSI signal, or crystal oscillator. Page 30 of 140 PSoC® 3: CY8C38 Family Datasheet 6.2 Power System VDDIO pins must have capacitors connected as shown in Figure 6-4. The two VCCD pins must be shorted together, with as short a trace as possible, and connected to a 1-µF ±10-percent X5R capacitor. The power system also contains a sleep regulator, an I2C regulator, and a hibernate regulator. The power system consists of separate analog, digital, and I/O supply pins, labeled VDDA, VDDD, and VDDIOX, respectively. It also includes two internal 1.8-V regulators that provide the digital (VCCD) and analog (VCCA) supplies for the internal core logic. The output pins of the regulators (VCCD and VCCA) and the Figure 6-4.

A trace under the device is recommended, as shown in Figure 2-8 on page 12.  It is good practice to check the datasheets for your bypass capacitors, specifically the working voltage and the DC bias specifications. With some capacitors, the actual capacitance can decrease considerably when the DC bias (VDDX or VCCX in Figure 6-4) is a significant percentage of the rated working voltage.  You can power the device in internally regulated mode, where the voltage applied to the VDDx pins is as high as 5.5 V, and the internal regulators provide the core voltages. In this mode, do not apply power to the VCCx pins, and do not tie the VDDx pins to the VCCx pins.  You can also power the device in externally regulated mode, that is, by directly powering the VCCD and VCCA pins. In this configuration, the VDDD pins should be shorted to the VCCD pins and the VDDA pin should be shorted to the VCCA pin. The allowed supply range in this configuration is 1.71 V to 1.89 V. After power up in this configuration, the internal regulators are on by default, and should be disabled to reduce power consumption. Document Number: 001-11729 Rev. AH Page 31 of 140 PSoC® 3: CY8C38 Family Datasheet 6.2.1 Power Modes PSoC 3 devices have four different power modes, as shown in Table 6-2 and Table 6-3. The power modes allow a design to easily provide required functionality and processing power while simultaneously minimizing power consumption and maximizing battery life in low-power and portable devices. PSoC 3 power modes, in order of decreasing power consumption are:  Active  Alternate Active  Sleep Active is the main processing mode. Its functionality is configurable. Each power controllable subsystem is enabled or disabled by using separate power configuration template registers. In alternate active mode, fewer subsystems are enabled, reducing power. In sleep mode most resources are disabled regardless of the template settings. Sleep mode is optimized to provide timed sleep intervals and Real Time Clock functionality. The lowest power mode is hibernate, which retains register and SRAM state, but no clocks, and allows wakeup only from I/O pins. Figure 6-5 on page 33 illustrates the allowable transitions between power modes. Sleep and hibernate modes should not be entered until all VDDIO supplies are at valid voltage levels.  Hibernate Table 6-2.

All devices in the PSoC 3 CY8C38 family comply to RoHS-6 specifications, demonstrating the commitment by Cypress to lead-free products. Lead (Pb) is an alloying element in solders that has resulted in environmental concerns due to potential toxicity. Cypress uses nickel-palladium-gold (NiPdAu) technology for the majority of leadframe-based packages. A high-level review of the Cypress Pb-free position is available on our website. Specific package information is also available. Package Material Declaration data sheets (PMDDs) identify all substances contained within Cypress packages. PMDDs also confirm the absence of many banned substances. The information in the PMDDs will help Cypress customers plan for recycling or other “end of life” requirements.
