Family Overview The FastFLASH XC9500XL family is a 3.3V CPLD family targeted for high-performance, low-voltage applications in leading-edge communications and computing systems, where high device reliability and low power dissipation is important. Each XC9500XL device supports in-system programming (ISP) and the full IEEE 1149.1 (JTAG) boundary-scan, allowing superior debug and design iteration capability for small form-factor packages. The XC9500XL family is designed to work closely with the Xilinx Virtex, Spartan-XL and XC4000XL FPGA families, allowing system designers to partition logic optimally between fast interface circuitry and high-density general purpose logic. As shown in Table 1, logic density of the XC9500XL devices ranges from 800 to 6400 usable gates with 36 to 288 registers, respectively. Multiple package options and associated I/O capacity are shown in Table 2. The XC9500XL family members are fully pin-compatible, allowing easy design migration across multiple density options in a given package footprint. The XC9500XL architectural features address the requirements of in-system programmability. Enhanced pin-locking capability avoids costly board rework. In-system programming throughout the full commercial operating range and a high programming endurance rating provide worry-free reconfigurations of system field upgrades. Extended data retention supports longer and more reliable system operating life. Advanced system features include output slew rate control and user-programmable ground pins to help reduce system noise. Each user pin is compatible with 5V, 3.3V, and 2.5V inputs, and the outputs may be configured for 3.3V or 2.5V 3 DS054 (v1.9) November 11, 2004 Preliminary Product Specification www.xilinx.com 1-800-255-7778 XC9500XL High-Performance CPLD Family Data Sheet operation. The XC9500XL device exhibits symmetric full 3.3V output voltage swing to allow balanced rise and fall times. Additional details can be found in the application notes listed in "Further Reading" on page 17. R Function Block Each Function Block, as shown in Figure 2 is comprised of 18 independent macrocells, each capable of implementing a combinatorial or registered function. The FB also receives global clock, output enable, and set/reset signals. The FB generates 18 outputs that drive the FastCONNECT switch matrix. These 18 outputs and their corresponding output enable signals also drive the IOB. Logic within the FB is implemented using a sum-of-products representation. Fifty-four inputs provide 108 true and complement signals into the programmable AND-array to form 90 product terms. Any number of these product terms, up to the 90 available, can be allocated to each macrocell by the product term allocator. Architecture Description Each XC9500XL device is a subsystem consisting of multiple Function Blocks (FBs) and I/O Blocks (IOBs) fully interconnected by the FastCONNECT II switch matrix. The IOB provides buffering for device inputs and outputs. Each FB provides programmable logic capability with extra wide 54inputs and 18 outputs. The FastCONNECT II switch matrix connects all FB outputs and input signals to the FB inputs. For each FB, up to 18 outputs (depending on package pin-count) and associated output enable signals drive directly to the IOBs. See Figure 1 Macrocell 1 Programmable AND-Array From FastCONNECT II Switch Matrix 54 Product Term Allocators 18 18 18 To FastCONNECT II Switch Matrix OUT To I/O Blocks PTOE Macrocell 18 1 3 Global Global Set/Reset Clocks DS054_02_042101 Figure 2: XC9500XL Function Block Macrocell Each XC9500XL macrocell may be individually configured for a combinatorial or registered function. The macrocell and associated FB logic is shown in Figure 3. Five direct product terms from the AND-array are available for use as primary data inputs (to the OR and XOR gates) to implement combinatorial functions, or as control inputs including clock, clock enable, set/reset, and output enable. The product term allocator associated with each macrocell selects how the five direct terms are used. The macrocell register can be configured as a D-type or T-type flip-flop, or it may be bypassed for combinatorial operation. Each register supports both asynchronous set and reset operations. During power-up, all user registers 4 www.xilinx.com 1-800-255-7778 DS054 (v1.9) November 11, 2004 Preliminary Product Specification R XC9500XL High-Performance CPLD Family Data Sheet are initialized to the user-defined preload state (default to 0 if unspecified). 54 Global Set/Reset Global Clocks 3 Additional Product Terms (from other macrocells) Product Term Set 1 0 S D/T Q To FastCONNECTII Switch Matrix Product Term Allocator CE Product Term Clock Enable Product Term Clock Product Term Reset OUT Product Term OE PTOE To I/O Blocks R Additional Product Terms (from other macrocells) DS054_03_042101 Figure 3: XC9500XL Macrocell Within Function Block All global control signals are available to each individual macrocell, including clock, set/reset, and output enable signals. As shown in Figure 4, the macrocell register clock originates from either of three global clocks or a product term clock. Both true and complement polarities of the selected clock source can be used within each macrocell. A GSR input is also provided to allow user registers to be set to a user-defined state.

The timing of the direct product terms is not changed. Product Term Allocator Product Term Allocator The product term allocator controls how the five direct product terms are assigned to each macrocell. For example, all five direct terms can drive the OR function as shown in Figure 5. Product Term Allocator Macrocell Product Term Logic Product Term Allocator DS054_05_042101 Figure 5: Macrocell Logic Using Direct Product Term The product term allocator can re-assign other product terms within the FB to increase the logic capacity of a macrocell beyond five direct terms. Any macrocell requiring additional product terms can access uncommitted product terms in other macrocells within the FB. Up to 15 product terms can be available to a single macrocell with only a small incremental delay of tPTA, as shown in Figure 6. Product Term Allocator Macrocell Logic With 15 Product Terms DS054_06_042101 Figure 6: Product Term Allocation With 15 Product Terms DS054 (v1.9) November 11, 2004 Preliminary Product Specification www.xilinx.com 1-800-255-7778 7 XC9500XL High-Performance CPLD Family Data Sheet The product term allocator can re-assign product terms from any macrocell within the FB by combining partial sums of products over several macrocells, as shown in Figure 7. In this example, the incremental delay is only 2*TPTA. All 90 product terms are available to any macrocell, with a maximum incremental delay of 8*TPTA.

All IOB outputs (corre- sponding to user pin inputs) and all FB outputs drive the FastCONNECT II matrix.

The input buffer uses the internal 3.3V voltage supply (VCCINT) to ensure that the input thresholds are constant and do not vary with the VCCIO voltage. Each input buffer provides input hysteresis (50 mV DS054 (v1.9) November 11, 2004 Preliminary Product Specification typical) to help reduce system noise for input signals with slow rise or fall edges. Each output driver is designed to provide fast switching with minimal power noise. All output drivers in the device may be www.xilinx.com 1-800-255-7778 11 XC9500XL High-Performance CPLD Family Data Sheet configured for driving either 3.3V CMOS levels (which are compatible with 5V TTL levels as well) or 2.5V CMOS levels by connecting the device output voltage supply (VCCIO) to a 3.3V or 2.5V voltage supply. Figure 11 shows how the XC9500XL device can be used in 3.3V only systems and mixed voltage systems with any combination of 5V, 3.3V and 2.5V power supplies. Each output driver can also be configured for slew-rate limited operation. Output edge rates may be slowed down to reduce system noise (with an additional time delay of tSLEW) under user control. See Figure 12. The output enable may be generated from one of four options: a product term signal from the macrocell, any of the global output enable signals (GTS), always "1," or always "0." There are two global output enables for devices with 72 or fewer macrocells, and four global output enables for devices with 144 or more macrocells. Any selected output enable signal may be inverted locally at each pin output to provide maximal design flexibility. Each IOB provides user programmable ground pin capability. This allows device I/O pins to be configured as additional ground pins in order to force otherwise unused pins to a low voltage state, as well as provide for additional device 5V CMOS 5V 0V R grounding capability. This grounding of the pin is achieved by internal logic that forces a logic low output regardless of the internal macrocell signal, so the internal macrocell logic is unaffected by the programmable ground pin capability. Each IOB also provides for bus-hold circuitry (also called a "keeper")that is active during valid user operation. The bus-hold feature eliminates the need to tie unused pins either high or low by holding the last known state of the input until the next input signal is present. The bus-hold circuit drives back the same state via a nominal resistance (RBH) of 50k ohms. See Figure 13. Note the bus-hold output will drive no higher than VCCIO to prevent overdriving signals when interfacing to 2.5V components. When the device is not in valid user operation, the bus-hold circuit defaults to an equivalent 50k ohm pull-up resistor in order to provide a known repeatable device state. This occurs when the device is in the erased state, in programming mode, in JTAG INTEST mode, or during initial power-up. A pull-down resistor (1k ohm) may be externally added to any pin to override the default RBH resistance to force a low state during power-up or any of these other modes. 5V CMOS 3.3V 5V 0V 3.3V VCCINT 2.5V VCCIO 2.5V CMOS 5V TTL or 5V 0V VCCINT VCCIO 3.3V CMOS, 5V TTL 3.3V 0V 5V TTL or 5V 3.3V CMOS or 3.3V 0V XC9500XL CPLD IN OUT 0V 3.3V CMOS or 3.3V 0V IN XC9500XL CPLD OUT 2.5V 0V 2.5V CMOS 2.5V 0V GND 2.5V CMOS 2.5V GND (a) 0V (b) DS054_11_042101 Figure 11: XC9500XL Devices in (a) 3.3V only and (b) Mixed 5V/3.3V/2.5V Systems 5V Tolerant I/Os The I/Os on each XC9500XL device are fully 5V tolerant even though the core power supply is 3.3 volts. This allows 5V CMOS signals to connect directly to the XC9500XL inputs without damage. In addition, the 3.3V VCCINT power supply can be applied before or after 5V signals are applied to the I/Os. In mixed 5V/3.3V/2.5V systems, the user pins, the core power supply (VCCINT), and the output power supply (VCCIO) may have power applied in any order. This makes the XC9500XL devices immune to power supply sequencing problems. Xilinx proprietary ESD circuitry and high impedance initial state permit hot plugging cards using these devices. Pin-Locking Capability The capability to lock the user defined pin assignments during design iteration depends on the ability of the architecture to adapt to unexpected changes. The XC9500XL devices incorporate architectural features that enhance the ability to accept design changes while maintaining the same pinout. 12 www.xilinx.com 1-800-255-7778 DS054 (v1.9) November 11, 2004 Preliminary Product Specification R XC9500XL High-Performance CPLD Family Data Sheet For extensive design changes requiring higher logic capacity than is available in the initially chosen device, the new design may be able to fit into a larger pin-compatible device using the same pin assignments. The same board may be used with a higher density device without the expense of board rework. The XC9500XL architecture provides for superior pin-locking characteristics with a combination of large number of routing switches in the FastCONNECT II switch matrix, a 54-wide input Function Block, and flexible, bi-directional product term allocation within each macrocell. These features address design changes that require adding or changing internal routing, including additional signals into existing equations, or increasing equation complexity, respectively.

If a particular signal must remain low during this time, then a pulldown resistor may be added to the pin. Set to PIN during valid user operation Drive to VCCIO Level 0 PIN External Programming RBH I/O XC9500XL devices can also be programmed by the Xilinx HW-130 device programmer as well as third-party programmers. This provides the added flexibility of using pre-programmed devices during manufacturing, with an in-system programmable option for future enhancements and design changes. Reliability and Endurance DS054_13_042101 Figure 13: Bus-Hold Logic In-System Programming One or more XC9500XL devices can be daisy chained together and programmed in-system via a standard 4-pin JTAG protocol, as shown in Figure 14. In-system programming offers quick and efficient design iterations and eliminates package handling. The Xilinx development system provides the programming data sequence using a Xilinx download cable, a third-party JTAG development system, JTAG-compatible board tester, or a simple microprocessor interface that emulates the JTAG instruction sequence. DS054 (v1.9) November 11, 2004 Preliminary Product Specification All XC9500XL CPLDs provide a minimum endurance level of 10,000 in-system program/erase cycles and a minimum data retention of 20 years. Each device meets all functional, performance, and data retention specifications within this endurance limit. IEEE 1149.1 Boundary-Scan (JTAG) XC9500XL devices fully support IEEE 1149.1 boundary-scan (JTAG). EXTEST, SAMPLE/PRELOAD, BYPASS, USERCODE, INTEST, IDCODE, HIGHZ and CLAMP instructions are supported in each device. Additional instructions are included for in-system programming operations. www.xilinx.com 1-800-255-7778 13 XC9500XL High-Performance CPLD Family Data Sheet R Design Security XC9500XL devices incorporate advanced data security features which fully protect the programming data against unauthorized reading or inadvertent device erasure/reprogramming. Table 3 shows the four different security settings available. The read security bits can be set by the user to prevent the internal programming pattern from being read or copied. When set, they also inhibit further program operations but allow device erase. Erasing the entire device is the only way to reset the read security bit. The write security bits provide added protection against accidental device erasure or reprogramming when the JTAG pins are subject to noise, such as during system power-up. Once set, the write-protection may be deacti- vated when the device needs to be reprogrammed with a valid pattern with a specific sequence of JTAG instructions.

This feature allows the device power to be significantly reduced. Each individual macrocell may be programmed in low-power mode by the user. Performance-critical parts of the application can remain in standard power mode, while other parts of the application may be programmed for low-power operation to reduce the overall power dissipation. Macrocells programmed for low-power mode incur additional delay (tLP) in pin-to-pin combinatorial delay as well as register setup time. Product term clock to output and product term output enable delays are unaffected by the macrocell power-setting. Signals switching at rates less than 50 ns rise/fall time should be assigned to the macrocells configured in low power mode. Timing Model The uniformity of the XC9500XL architecture allows a simplified timing model for the entire device. The basic timing model, shown in Figure 15, is valid for macrocell functions that use the direct product terms only, with standard power setting, and standard slew rate setting. Table 4 shows how each of the key timing parameters is affected by the product term allocator (if needed), low-power setting, and slew-limited setting. The product term allocation time depends on the logic span of the macrocell function, which is defined as one less than the maximum number of allocators in the product term path. If only direct product terms are used, then the logic span is 0. The example in Figure 6 shows that up to 15 product terms are available with a span of 1. In the case of Figure 7, the 18 product term function has a span of 2. 14 www.xilinx.com 1-800-255-7778 DS054 (v1.9) November 11, 2004 Preliminary Product Specification R XC9500XL High-Performance CPLD Family Data Sheet for each parameter are given in the individual device data sheets.

During power-up each XC9500XL device employs internal circuitry which keeps the device in the quiescent state until the VCCINT supply voltage is at a safe level (approximately 2.5V). During this time, all device pins and JTAG pins are disabled and all device outputs are disabled with the pins weakly pulled high, as shown in Table 5. When the supply voltage reaches a safe level, all user registers become initialized (typically within 200 s), and the device is immediately available for operation, as shown in Figure 17. If the device is in the erased state (before any user pattern is programmed), the device outputs remain disabled with weak pull-up. The JTAG pins are enabled to allow the device to be programmed at any time. All devices are shipped in the erased state from the factory. If the device is programmed, the device inputs and outputs take on their configured states for normal operation. The JTAG pins are enabled to allow device erasure or boundary-scan tests at any time.
