Description The ATF1508BE is a high-performance, high-density complex programmable logic device (CPLD) that utilizes Atmel’s proven electrically-erasable memory technology. With 128 logic macrocells and up to 84 inputs, it easily integrates logic from several TTL, SSI, MSI, LSI and classic PLDs. The ATF1508BE’s enhanced routing switch matrices increase usable gate count and the odds of successful pin-locked design modifications. The ATF1508BE has up to 80 bi-directional I/O pins and four dedicated input pins. Each dedicated input pin can also serve as a global control signal, register clock, register reset or output enable. Each of these control signals can be selected for use individually within each macrocell. Figures 1-1 and 1-2 show the pin assignments for the 100-lead TQFP and 132-ball CBGA packages, respectively. 2 ATF1508BE 3663A–PLD–1/08 ATF1508BE Figure 1-1. 100-lead TQFP Top View I/O I/O I/O I/O I/O GND I/O I/O I/O VCCINT INPUT/OE2/GCLK2 INPUT/GCLR INPUT/OE1 INPUT/GCLK1 GND I/O/GCLK3 I/O I/O VCCIOB I/O I/O I/O I/O I/O I/O 100 99 98 97 96 95 94 93 92 91 90 89 88 87 86 85 84 83 82 81 80 79 78 77 76 I/O/PD1 I/O VCCIOA I/O/TDI I/O I/O I/O I/O I/O I/O GND VREFA / I/O I/O I/O I/O/TMS I/O I/O VCCIOA I/O I/O I/O I/O I/O I/O I/O 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 33 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 49 50 75 74 73 72 71 70 69 68 67 66 65 64 63 62 61 60 59 58 57 56 55 54 53 52 51 I/O GND I/O/TDO I/O I/O I/O I/O I/O I/O VCCIOB I/O I/O I/O I/O/TCK I/O I/O / VREFB GND I/O I/O I/O I/O I/O I/O I/O VCCIOB GND I/O I/O I/O I/O I/O I/O I/O VCCIOA I/O I/O I/O GND VCCINT I/O I/O/PD2 I/O GND I/O I/O I/O I/O I/O I/O I/O 3 3663A–PLD–1/08 Figure 1-2. 132-CBGA Top View 1 2 3 4 5 6 7 8 9 10 11 12 13 14 A I/O VCCINT I/GCLR I/O I/O NC VCCIOB NC GND I/O I/O I/O NC VCCIOB B I/O I/O GND I/O I/O NC NC NC I/O/TDO NC I/O I/O NC GND C I/O I/OE1 I/OE2/ VCCIOB GCLK2 NC I/O I/O NC NC I/O I/O I/O I/O NC NC D I/O I/O I/O I/O I/O E I/O I/O I/O I/O I/O GND F I/O/PD1 I/O I/O I/O I/O I/O G I/O I/O I/O I/O/PD2 I/O VCCIOA H I/O/VREFA I/O I/O I/O I/O GND J I/O I/O VCCIOA I/O I/O GND K I/O GND I/O VCCNT I/O I/O L NC I/GCLK1 NC I/O I/O/VREFB I/O M NC NC I/O I/O I/O I/O NC I/O I/O/TDI I/O/TCK I/O NC NC NC N GND NC I/O NC I/O I/O NC NC GND I/O/TMS I/O GND I/O I/O P VCCINT I/O I/O GND I/O NC VCCIOA NC I/O I/O I/O I/O VCCIOA I/O Note: 1.

Block Diagram 10 16 10 5 3663A–PLD–1/08 Each of the 128 macrocells generates a buried feedback signal that goes to the global bus (see Figure 1-3). Each input and I/O pin also feeds into the global bus. The switch matrix in each logic block then selects 40 individual signals from the global bus. Each macrocell also generates a foldback logic term that goes to a regional bus. Cascade logic between macrocells in the ATF1508BE allows fast, efficient generation of complex logic functions. The ATF1508BE contains eight such logic chains, each capable of creating sum term logic with a fan-in of up to 40 product terms. The ATF1508BE macrocell, shown in Figure 1-4, is highly flexible and capable of supporting complex logic functions operating at high speed. The macrocell consists of five sections: product terms and product term select multiplexer, OR/XOR/CASCADE logic, a flip-flop, output select and enable, and logic array inputs. A security fuse, when programmed, protects the contents of the ATF1508BE. Two bytes (16 bits) of User Electronic Signature are accessible to the user for purposes such as storing project name, part number, revision or date. The User Electronic Signature is accessible regardless of the state of the security fuse. The ATF1508BE device supports In-System Programming (ISP) via the industry-standard 4-pin JTAG interface (IEEE 1532 standard), and is fully compliant with IEEE 1149.1 for Boundary Scan Test. ISP allows the device to be programmed without removing it from the printed circuit board. In addition to simplifying the manufacturing flow, ISP also allows design modifications to be made in the field via software. Figure 1-4. ATF1508BE Macrocell BURIED FEEDBACK SCHMITT TRIGGER SSTL 6 ATF1508BE 3663A–PLD–1/08 ATF1508BE 1.1 Product Terms and Select Mux Each ATF1508BE macrocell has five product terms. Each product term receives as its inputs all signals from the switch matrix and regional bus. The product term select multiplexer (PTMUX) allocates the five product terms as needed to the macrocell logic gates and control signals. The PTMUX configuration is determined by the design compiler, which selects the optimum macrocell configuration. 1.2 OR/XOR/CASCADE Logic The ATF1508BE’s logic structure is designed to efficiently support all types of logic. Within a single macrocell, all the product terms can be routed to the OR gate, creating a 5-input AND/OR sum term. With the addition of the CASIN from neighboring macrocells, this can be expanded to as many as 40 product terms with minimal additional delay. The macrocell’s XOR gate allows efficient implementation of compare and arithmetic functions. One input to the XOR comes from the OR sum term. The other XOR input can be a product term or a fixed high or low level. For combinatorial outputs, the fixed level input allows polarity selection. For registered functions, the fixed levels allow DeMorgan minimization of product terms. 1.3 Flip-flop The ATF1508BE’s flip-flop has very flexible data and control functions. The data input can come from either the XOR gate, from a separate product term or directly from the I/O pin. Selecting the separate product term allows creation of a buried registered feedback within a combinatorial output macrocell. (This feature is automatically implemented by the fitter software). In addition to D, T, JK and SR operation, the flip-flop can also be configured as a flow-through latch. In this mode, data passes through when the clock is high and is latched when the clock is low. The clock itself can be any one of the Global CLK signals (GCK[0 : 2]) or an individual product term. The flip-flop changes state on the clock’s rising edge. When the GCK signal is used as the clock, one of the macrocell product terms can be selected as a clock enable. When the clock enable function is active and the enable signal (product term) is low, all clock edges are ignored. The flip-flop’s asynchronous reset signal (AR) can be either the Global Clear (GCLEAR), a product term, or always off. AR can also be a logic OR of GCLEAR with a product term. The asynchronous preset (AP) can be a product term or always off. 1.4 Extra Feedback The ATF1508BE macrocell output can be selected as registered or combinatorial. The extra buried feedback signal can be either combinatorial or a registered signal regardless of whether the output is combinatorial or registered. (This enhancement function is automatically implemented by the fitter software.) Feedback of a buried combinatorial output allows the creation of a second latch within a macrocell. 1.5 I/O Control The output enable multiplexer (MOE) controls the output enable signal. Each I/O can be individually configured as an input, output or bi-directional pin. The output enable for each macrocell can be selected from the true or complement of the two output enable pins, a subset of the I/O pins, or a subset of the I/O macrocells. This selection is automatically done by the fitter software when the I/O is configured as an input or bi-directional pin. 7 3663A–PLD–1/08 1.6 Global Bus/Switch Matrix The global bus contains all input and I/O pin signals as well as the buried feedback signal from all 128 macrocells. The switch matrix in each logic block receives as its inputs all signals from the global bus. Under software control, up to 40 of these signals can be selected as inputs to the logic block. 1.7 Foldback Bus Each macrocell also generates a foldback product term. This signal goes to the regional bus and is available to all 16 macrocells within the logic block. The foldback is an inverse polarity of one of the macrocell’s product terms. The 16 foldback terms in each logic block allow generation of high fan-in sum terms or other complex logic functions with little additional delay. 2. Input and I/O Pins 2.1 Programmable Pin-keeper Option for Inputs and I/Os The ATF1508BE offers the option of individually programming each of its input or I/O pin so that pin-keeper circuit can be utilized. When any pin is driven high or low and then subsequently left floating, it will stay at that previous high or low level. This circuitry prevents undriven input and I/O lines from floating to intermediate voltage levels, which causes unnecessary power consumption and system noise. The keeper circuits eliminate the need for external pull-up resistors and eliminate their DC power consumption. Figure 2-1 shows the pin-keeper circuit for an Input Pin and Figure 2-2 shows the same for an I/O pin. The pin-keeper circuit is a weak feedback latch and has an effective resistance that is approximately 50 kΩ. Figure 2-1.

I/O with Programmable Pin-keeper VCCIO VCCINT 50K 2.2 Schmitt Trigger The Input Buffer of each input and I/O pin has an optional schmitt trigger setting. The schmitt trigger option can be used to buffer inputs with slow rise times. 2.3 Output Drive Capability Each output has a high/low drive option. The low drive option (slow slew rate) can be used to reduce system noise by slowing down outputs that do not need to operate at maximum speed or drive strength. Outputs default to high drive strength by Atmel software and can be set to low drive strength through the slew rate option. 2.4 I/O Bank The I/O pins of the ATF1508BE are grouped into two banks, Bank A and Bank B. Bank A comprises of I/O pins for macrocells 1 to 64 (Logic Block A, B, C, and D), and it is powered by VCCIOA. Bank B comprises of I/O pins for macrocells 65 to 128 (Logic Block E, F, G, and H), and it is powered by VCCIOB. 2.5 I/O Standard The ATF1508BE supports a wide range of I/O standards which include LVTTL, LVCMOS33, LVCMOS25, LVCMOS18 and LVCMOS15. The I/O pins of the ATF1508BE can also be individually configured to support SSTL-2 (Class I) and SSTL-3 (Class I) advanced I/O standards. This and the two I/O banks, together, allow the ATF1508BE to be used for voltage level translation. 9 3663A–PLD–1/08 3. Power Management Unlike conventional CPLDs with sense amplifiers, the ATF1508BE is designed using low-power full CMOS design techniques. This enables the ATF1508BE to achieve extremely low power consumption over the full operating frequency spectrum. The ATF1508BE also has an optional power-down mode. In this mode, current drops to below 100 µA. When the power-down option is selected, either PD1 or PD2 pins (or both) can be used to power down the part. When enabled, the device goes into power-down when either PD1 or PD2 is high. In the power-down mode, all internal logic signals are latched and held, as are any enabled outputs. All pin transitions are ignored until the PD pin is brought low. When the power-down feature is enabled, the PD1 or PD2 pin cannot be used as a logic input or output. However, the pin’s macrocell may still be used to generate buried foldback and cascade logic signals. All power-down AC characteristic parameters are computed from external input or I/O pins. 4. Security Feature A fuse is provided to prevent unauthorized copying of the ATF1508BE fuse patterns. Once enabled, fuse reading or verification is inhibited. However, the 16-bit User Electronic Signature remains accessible. To reset this feature, the entire memory array in the device must be erased. 5. Programming Methods The ATF1508BE devices are In-System Programmable (ISP) or In-System Configurable (ISC) devices utilizing the 4-pin JTAG protocol. This capability eliminates package handling normally required for programming and facilitates rapid design iterations and field changes. When using the ISP hardware or software to program the ATF1508BE devices, four I/O pins must be reserved for the JTAG interface. However, the logic features that the macrocells have associated with these I/O pins are still available to the design for buried logic functions. To facilitate ISP programming by the Automated Test Equipment (ATE) vendors, Serial Vector Format (SVF) files can be created by Atmel-provided software utilities. ATF1508BE devices can also be programmed using standard third-party programmers. With a third-party programmer, the JTAG ISP port can be disabled, thereby allowing four additional I/O pins to be used for logic. The ATF1508BE device supports several configuration modes which gives designers several unique options for programming. The different modes of programming are: • ISC – In-System Configuration • OTF – On-the-Fly Reconfiguration • DRA – Direct Reconfiguration Access 10 ATF1508BE 3663A–PLD–1/08 ATF1508BE 5.1 In-System Configuration – ISC (Also Referred to as ISP) This mode is the de-facto standard used to program the CPLD when it is attached to a PCB. The term ISC can also be used interchangeably with ISP (In-system Programming). ISC or ISP eliminates the need for an external device programmer, and the devices can be soldered to a PCB without being preprogrammed. In the ISC mode, the logic operation of the ATF1508BE is halted and the embedded configuration memory is programmed. The device is programmed by first erasing the configuration memory in the CPLD and then loading the new configuration data into the memory, which in-turn configures the PLD for functional mode. When the device is in the ISC programming mode, all user I/Os are held in the high impedance state. The ISC mode is best suited for working with the ATF1508BE device in a design development or production environment. Configuration of the ATF1508BE device done via a Download Cable (see Figure 5-1 on page 11) is the default mode used to program the device in the ISC mode. In this mode, the PC is typically the controlling device that communicates with the CPLD. Figure 5-1. Configuration of ATF1508BE Device Using a Download Cable ATF1508BE CPLD Device TCK TDO 1 3 2 4 6 8 10 Connect ISP Download Cable to 10-pin JTAG Header VCC TMS TDI 5 7 9 JTAG Connector 5.2 On-the-Fly Reconfiguration – OTF In this mode, the CPLD design pattern stored in the internal configuration memory can be modified while the previously-programmed design pattern is operating with minimal disturbance to the programming operation of the new design. The new configuration will take affect after the OTF programming process is completed and the OTF mode is exited. The configuration data for any design is stored in the internal configuration memory. Once the configuration data is transferred to the internal static registers of the CPLD, the CPLD operates with the design pattern and the configuration memory is free to be re-loaded with a new set of configuration data. The design pattern due to the new configuration content is activated through an initialization cycle that occurs on exiting the OTF mode or after the next power up sequence. Figure 5-2 shows the electrical interface for configuration of the ATF1508BE device in the OTF mode. The processor is the controlling device that communicates with the CPLD and uses configuration data stored in the external memory to configure the CPLD. 11 3663A–PLD–1/08 Figure 5-2. Configuration of ATF1508BE Device Using a Processor and Memory ATF1508BE CPLD Device TCK TDO Processor TMS TDI Serial Data Data Address Memory 5.3 Direct Reconfiguration Access – DRA This reconfiguration mode allows the user to directly modify the internal static registers of the CPLD without affecting the configuration data stored in the embedded memory. It is more useful in cases where immediate and temporary context change in the function of the hardware is desired. The embedded configuration memory in the ATF1508BE does not change when a new set of configuration data is passed to the ATF1508BE using the DRA mode. Instead, the internal static registers of the CPLD are directly written with the data entering the device via the JTAG port. In other words, it's a temporary change in the function performed by the CPLD since a power sequence results in the device being configured again by the data stored in the embedded memory. 5.4 ISP Programming Protection The ATF1508BE has a special feature that locks the device and prevents the inputs and I/O from driving if the programming process is interrupted for any reason. The I/O pins default to high-Z state during such a condition. All ATF1508BE devices are initially shipped in the erased state, thereby making them ready to use for ISP. 12 ATF1508BE 3663A–PLD–1/08 ATF1508BE 6. JTAG-BST/ISP Overview The JTAG boundary-scan testing is controlled by the Test Access Port (TAP) controller in the ATF1508BE. The boundary-scan technique involves the inclusion of a shift-register stage (contained in a boundary-scan cell) adjacent to each component so that signals at component boundaries can be controlled and observed using scan testing methods. Each input pin and I/O pin has its own boundary-scan cell (BSC) to support boundary-scan testing. The TAP controller is automatically reset at power-up. The five JTAG modes supported include: SAMPLE/PRELOAD, EXTEST, BYPASS, IDCODE and HIGHZ. The ATF1508BE’s BSC can be fully described using a BSDL file as described in IEEE 1149.1 standard. This allows ATF1508BE testing to be described and implemented using any one of the third-party development tools supporting this standard. The ATF1508BE also has the option of using the four JTAG-standard I/O pins for ISP. The ATF1508BE is programmable through the four JTAG pins using the IEEE standard JTAG programming protocol established by IEEE 1532 standard using 1.8V/2.5V/3.3V LVCMOS level programming signals from the ISP interface for in-system programming. The JTAG feature is a programmable option. If JTAG (BST or ISP) is not needed, then the four JTAG control pins are available as I/O pins. 6.1 JTAG Boundary-scan Cell (BSC) Testing The ATF1508BE contains 80 I/O pins and four dedicated input pins. Each input pin and I/O pin has its own boundary-scan cell (BSC) in order to support boundary-scan testing as described in detail by IEEE 1532 standard. A typical BSC consists of three capture registers or scan registers and up to two update registers. There are two types of BSCs, one for input or I/O pin, and one for the macrocells. The BSCs in the device are chained together through the capture registers. Input to the capture register chain is fed in from the TDI pin while the output is directed to the TDO pin. Capture registers are used to capture active device data signals, to shift data in and out of the device and to load data into the update registers. Control signals are generated internally by the JTAG TAP controller. The BSC configuration for the input and I/O pins and macrocells is shown below. Figure 6-1. BSC Configuration for Input and I/O Pins (Except JTAG TAP Pins) Note: The ATF1508BE has a pull-up option on TMS and TDI pins. This feature is selected as a design option. 13 3663A–PLD–1/08 Figure 6-2.

Design Software Support ATF1508BE designs are supported by several third-party tools. Automated fitters allow logic synthesis using a variety of high-level description languages such as VHDL® and Verilog®. Third party synthesis and simulation tools from Mentor Graphics® are integrated into Atmel’s software tools. 14 ATF1508BE 3663A–PLD–1/08 ATF1508BE 8. Electrical Specifications Table 8-1.

Power-down Mode The ATF1508BE includes an optional pin-controlled power-down feature. When this mode is enabled, the PD pin acts as the power-down pin. When the PD pin is high, the device supply current is reduced to less than 100 µA. During power-down, all output data and internal logic states are latched and held. Therefore, all registered and combinatorial output data remain valid. Any outputs that were in a high-Z state at the onset will remain at high-Z. During power-down, all input signals except the power-down pin are blocked. Input and I/O hold latches remain active to ensure that pins do not float to indeterminate levels, further reducing system power. The powerdown pin feature is enabled in the logic design file or through Atmel software. Designs using the power-down pin may not use the PD pin logic array input. However, all other PD pin macrocell resources may still be used, including the buried feedback and foldback product term array inputs. Table 12-1.
