XC9572XL-7VQ64I - 3.3V CPLD 72MC 7.5ns 64-TQFP | Xilinx
MPN: XC9572XL-7VQ64I ✓ ActiveXC9572XL-7VQ64I Overview
A Complex Programmable Logic Device (CPLD) is a family of programmable logic ICs that sits between simple SPLDs (such as GAL and PAL devices) and large FPGAs in the programmable logic hierarchy. CPLDs use a macrocell-based architecture with a deterministic pin-to-pin delay, making them well suited to glue logic, bus interface, state machine and power-sequencing tasks where predictable timing and instant-on operation matter more than logic density.
The XC9572XL belongs to the FastFLASH XC9500XL high-performance, low-voltage CPLD family targeted at leading-edge communications and computing systems where device reliability and low power dissipation are important. Key features include individual output enable per output pin with local inversion, input hysteresis on all user and boundary-scan pin inputs, bus-hold circuitry on all user pin inputs, and hot-plugging capability.
Every XC9500XL device supports in-system programming (ISP) with a minimum of 10,000 program/erase cycles, and full IEEE Std 1149.1 (JTAG) boundary-scan, giving engineers superior debug and design-iteration capability without removing devices from the board. The -7 speed grade delivers 7.5 ns maximum pin-to-pin propagation delay, and the industrial temperature rating (-40C to +85C) qualifies the part for harsh environments. Lead finish is tin with 0.5 mm lead pitch per the manufacturer product information.
Typical applications include communications and networking line-card glue logic, industrial control state machines, bus-interface and address-decode functions, and microprocessor power-management sequencing, where a deterministic 7.5 ns delay and instant power-up behavior outperform FPGA-based solutions.
Design consideration: the XC9500XL family is programmed with the legacy Xilinx ISE toolchain, so confirm toolchain availability in your development environment before committing to new designs; bus-hold on unused inputs removes the need for external pull resistors.

Typical Applications
XC9572XL-7VQ64I is suitable for 6 applications: Communications and Networking Glue Logic, Industrial Control State Machines, Bus Interface and Address Decoding, Processor Power Sequencing and Reset Management, Video and Display Interface Adaptation, Test and Measurement Instrument Logic.
Communications and Networking Glue Logic
Line cards, switches and routers in communications equipment need deterministic glue logic between processors, PHYs and backplane connectors. The XC9572XL-7VQ64I fits this role with a guaranteed 7.5 ns maximum pin-to-pin delay that does not depend on routing, so address decode and handshaking timing can be calculated by inspection rather than by static timing closure. Its 52 user I/O pins in one 64-TQFP handle wide address/data buses, and per-pin output enables with local inversion support shared backplane buses. Hot-plugging capability and input hysteresis on all inputs allow live insertion into powered backplanes, while bus-hold circuitry keeps un-driven backplane signals at valid logic levels without external pull resistors, reducing component count and improving noise margins in noisy card cages.
Recommended
Industrial Control State Machines
Factory automation, motor-control sequencing and machine safety interlocks frequently implement simple but timing-critical state machines. The XC9572XL-7VQ64I provides 72 macrocells, enough for multi-state sequencers with counters and comparators, and its -40C to +85C industrial rating matches the ambient extremes of control cabinets. The Flash fabric powers up instantly with the configured logic active, so machinery control is valid from the first microsecond, unlike FPGAs that need configuration time. Ten-thousand program/erase cycles allow in-field logic updates through the JTAG port during maintenance. Bus-hold on all user inputs prevents floating sensor lines from oscillating, and the deterministic 7.5 ns delay keeps response times predictable for interlock and safety-adjacent logic paths.
Recommended
Bus Interface and Address Decoding
Legacy processor buses, memory-mapped peripheral expansions and multi-chip backplanes need wide, fast address decode. The XC9572XL-7VQ64I offers 52 user I/O, sufficient for full 32-bit address latching and multiple chip-select outputs in a single VQ64 package. Individual output enables per pin with local inversion allow direct tri-state connection to shared buses without external transceivers in many designs, and the 7.5 ns maximum delay supports chip-select generation for reasonably fast memories with straightforward timing budgets. Input hysteresis improves margin on long, slow-rise bus traces. Because the design source is retained in Flash with 10,000-cycle endurance, address maps can be reprogrammed in-system when board revisions change memory assignments.
Recommended
Processor Power Sequencing and Reset Management
Multi-rail processors require precisely ordered enable signals for their core, I/O and peripheral supplies. The XC9572XL-7VQ64I implements voltage-monitor-based sequencers that generate reset and enable trees with deterministic 7.5 ns response, and instant-on operation means sequencing is valid immediately at power-up without configuration latency. Its 3.3 V supply matches typical monitoring thresholds, hot-plug tolerance supports live backplane insertion, and input hysteresis prevents chatter near comparator thresholds. With 52 I/O pins, one device can sequence several regulators plus level-shifted enable outputs. In-system programmability lets firmware teams tune sequencing delays across product revisions without board respins, and JTAG boundary scan enables production-line verification of the assembled sequencing board.
Recommended
Video and Display Interface Adaptation
Video encoders, display panels and mixed-voltage graphics pipelines often need logic translation, sync generation and timing adaptation between a graphics source and a display device. The XC9572XL-7VQ64I contributes 72 macrocells for sync counters and blanking logic with a fixed 7.5 ns pin-to-pin delay that keeps pixel-clock domain timing stable and predictable. Its 52 I/O accommodate RGB buses plus control signals in one package, and 3.3 V operation matches modern graphics IC supplies. Input hysteresis tolerates slow or noisy sync edges from long cable runs, and bus-hold keeps panel control lines defined during standby. JTAG programming allows sync polarity and timing constants to be updated on production boards to match panel revisions.
Recommended
Test and Measurement Instrument Logic
Bench instruments, data-acquisition front ends and automated test equipment use small programmable logic for range switching, trigger arbitration and rear-panel interface logic. The XC9572XL-7VQ64I suits these designs because its deterministic 7.5 ns delay makes trigger-path latency measurable and repeatable, an important property when instrument specifications quote trigger jitter. The industrial temperature rating supports laboratory environments plus portable field equipment, and instant-on Flash operation means the instrument is ready the moment power is applied. In-system programming through the JTAG port enables calibration-related logic updates in the field, and boundary-scan support lets production test systems verify board interconnects automatically during final assembly and test.

Key Differentiators
- Faster than the 10 ns grade on the same footprint (vs XC9572XL-10VQG64I)
- Industrial temperature rating for harsh enclosures (vs XC9572XL-7VQ64C)
- Deterministic CPLD timing vs FPGA solutions (vs XC9572XL-5VQ64I)
Design Notes
The VQ64 TQFP has a 0.5 mm lead pitch. Use a land pattern per the manufacturer package drawing in the XC9500XL family datasheet, and route JTAG (TDI, TDO, TMS, TCK) as a daisy chain with series resistors near the connector when multiple JTAG devices share one chain. Provide at least one 0.1 uF ceramic decoupling capacitor per VCC pin pair placed within 2 mm of the package, plus a bulk 10 uF capacitor near the device. Fill unused user I/O as bus-hold keeps them defined, but tie them to a rail if the design must tolerate a disabled device.
Do not mix speed-grade timing assumptions: the -7 grade guarantees 7.5 ns maximum pin-to-pin delay, but internal macrocell setup/hold and global clock skew values must still be checked in the ISE timing report. Also, the XC9500XL family is programmed only by the legacy Xilinx ISE toolchain - confirm your toolchain runs in your current OS environment (community workarounds exist for newer Windows versions) before committing to new designs. Finally, verify the temperature suffix: the -I industrial part is rated -40C to +85C, while -C commercial parts stop at +70C and must not be used in industrial enclosures.
Bus-hold circuitry on all user inputs removes external pull resistors but adds a small holding current on tri-shared buses; account for it in bus capacitance recovery calculations when many devices share one line. Input hysteresis improves immunity on slow edges, but for long backplane traces still series-terminate the driver side (22 to 33 ohm) to control overshoot at the 3.3 V rail. Hot-plugging is supported, so TDI/TMS lines may be driven before VCC is stable - design backplane connectors so ground and VCC pins make contact before JTAG and bus pins.
