XC9572XL-5VQ44C - 72-Macrocell 3.3V CPLD TQFP-44 | AMD Xilinx
N.º da peça: XC9572XL-5VQ44C ✓ AtivoXC9572XL-5VQ44C Visão geral
A CPLD is a type of programmable logic device that sits between simple programmable logic devices (SPLDs such as GAL and PAL) and large FPGAs in the programmable-logic hierarchy. It consists of multiple function blocks with macrocells interconnected through a programmable switch matrix, delivering deterministic pin-to-pin timing that FPGAs cannot guarantee. This makes CPLDs ideal for glue logic, state machines, address decoding, and power-up configuration control in embedded systems.
The XC9572XL family belongs to the low-voltage branch of the classic XC9500 CPLD family, operating from a 3.3V supply, which reduces power consumption and simplifies integration with modern low-voltage logic. Key features include in-system programmability (ISP), 10,000 program/erase cycles of Flash endurance, and the FastFlash zero-power technology that combines very low standby current with high speed. The -5 speed grade denotes the fastest commercial timing grade in the family.
Architecturally, each macrocell is a fully flexible, registered function unit that can implement combinational or sequential logic, with product-term steering providing high DFT (design-for-test) flexibility. The switch matrix routes signals between function blocks and I/O pins with predictable, uniform delays, which is why the family is prized for timing-critical control logic and bus interfaces.
Typical applications include bus-interface bridging, address decoding in microprocessor systems, power-sequencing and reset control, legacy logic consolidation, and as a configuration controller companion for larger FPGAs. Retro-computing and industrial-control designs frequently adopt this part for its deterministic timing and reprogrammability.
When designing with this device, program it using the AMD/Xilinx ISE toolchain, which remains the supported software for the XC9500XL family; verify the JEDEC programming file targets the exact speed grade and package suffix. Note that ISE no longer installs natively on Windows 10, so plan a compatible tool environment early in the project.

Aplicações típicas
XC9572XL-5VQ44C é adequado para 6 aplicaçãos: Glue Logic and Address Decoding, FPGA Configuration and Reset Control, Industrial Control and Legacy Logic Consolidation, Bus Interface Bridging, Retro Computing and Restoration, Test and Measurement Instrument Logic.
Glue Logic and Address Decoding
The XC9572XL-5VQ44C is a classic choice for glue-logic consolidation in microprocessor and microcontroller systems, replacing dozens of discrete 74-series devices with a single reprogrammable CPLD. Its 72 macrocells implement address decoding, chip-select generation, and wait-state logic with deterministic pin-to-pin delay from the fast -5 speed grade, eliminating the timing uncertainty inherent in FPGA implementations. Because the switch matrix provides uniform routing delays, decoded chip-select edges arrive predictably at memory and peripheral devices. The 3.3V supply interfaces directly with modern low-voltage buses, and JTAG in-system programming lets you revise decode maps during board bring-up without desoldering the device.
Recomendado
FPGA Configuration and Reset Control
Around a larger FPGA, the XC9572XL-5VQ44C serves as a configuration controller, monitoring power-good signals, sequencing reset releases, latching mode pins, and gating the configuration-done handshake. CPLD deterministic timing is essential here: reset assertion must not race FPGA power-up, and the -5 speed grade guarantees sub-10ns-class pin-to-pin response so supervisor logic reacts within a known window. The 72-macrocell budget comfortably holds a reset state machine, brownout watchdog logic, and mode-pin multiplexing simultaneously. Because the CPLD is Flash-based and independently reprogrammable over JTAG, sequencing firmware can be corrected after PCB assembly, a significant advantage over fixed-logic or fuse-based solutions.
Recomendado
Industrial Control and Legacy Logic Consolidation
In industrial equipment, the XC9572XL-5VQ44C consolidates aging TTL/CMOS control boards into one Flash CPLD, extending service life of legacy machinery. The 10,000-cycle program/erase endurance permits repeated field updates of control logic as production requirements evolve, and the commercial temperature version fits climate-controlled cabinet environments. Deterministic macrocell timing simplifies safety-adjacent interlock logic because response times are fixed by the -5 speed grade rather than dependent on routing congestion. Designers commonly reproduce motor-enable interlocks, limit-switch debounce, and panel I/O mapping in the CPLD, dramatically reducing PCB area, component count, and spares inventory compared with discrete-logic boards.
Recomendado
Bus Interface Bridging
The XC9572XL-5VQ44C bridges dissimilar buses - for example, mapping an MCU parallel bus to a peripheral register file, or converting between legacy ISA-style timing and modern device interfaces. Its 72 macrocells implement bidirectional transceivers, byte-lane steering, and handshake state machines, while the high-speed -5 grade keeps propagation delay below bus-cycle budget. Consistent switch-matrix delays mean setup and hold timing at both bus ends is calculable from the DS057 datasheet tables without post-route simulation. The 3.3V I/O matches contemporary peripherals, and in-system programmability allows protocol refinements during system integration. This application exploits the CPLD strength of registered, wide-input decoding that few standard-logic families can match in one package.
Recomendado
Retro Computing and Restoration
Retro-computing projects, including hobbyist reproductions of classic computers, rely on the XC9572XL family because it faithfully reproduces vintage bus timing with deterministic delays that modern FPGAs cannot guarantee at low complexity. The 72 macrocells of the XC9572XL-5VQ44C implement address decoders, video sync generators, and bus arbiters for 8-bit and 16-bit home-computer architectures. Community projects such as RGBtoHDMI adapter discussions reference this family directly. The 3.3V supply and JTAG programming fit compact add-on boards, and reprogrammability lets enthusiasts iterate designs freely. The TQFP-44 footprint is hand-solderable, supporting prototype assembly without reflow equipment.
Recomendado
Test and Measurement Instrument Logic
Bench and rack instrumentation uses the XC9572XL-5VQ44C for trigger gating, range-switch control, and front-panel I/O timing where jitter-free, repeatable response matters. The -5 speed grade gives predictable nanosecond-class pin-to-pin latency for trigger chains, and the switch matrix ensures that logic changes do not perturb routing delays. Its 72 macrocells hold multiple independent control state machines, and 3.3V operation matches the logic levels of modern DSP and MCU front ends. Flash ISP allows calibration-related logic updates during production test without board rework, and the commercial temperature grade suits laboratory environments where instruments operate under controlled ambient conditions.

Notas de projeto
Program the device only with the AMD/Xilinx ISE toolchain and verify that the JEDEC file targets the exact speed grade and package suffix (5VQ44C). ISE no longer installs natively on Windows 10, so set up a supported OS environment or virtual machine before starting the project - discovering this during bring-up costs days. Also confirm power-up behavior: XC9500XL devices require stable VCC before JTAG programming, and hot-socketing limits in the DS057 datasheet must be observed in multi-rail systems.
Decouple the 3.3V rail with at least a 0.1uF ceramic capacitor close to each VCC pin plus one bulk 10uF capacitor per device, following the typical application guidance in the DS057 datasheet. Estimated: with all 72 macrocells toggling at moderate frequency, ICC dynamic current stays well under the family's rated ceiling, but tie all unused I/O to a defined logic level (ground or VCC through the design source) to prevent floating-node shooting current, which is the most common cause of higher-than-expected standby current in CPLD designs.
Reserve JTAG header access on the PCB even if the CPLD will be programmed only at manufacturing time - in-system programmability is this family's key lifecycle advantage and enables field logic updates. Keep JTAG traces short and series-terminate TCK near the header to limit ringing. For unused I/O, configure them as grounded outputs in the ISE source to improve noise immunity and reduce power. Confirm the TQFP-44 land pattern against the datasheet mechanical drawing before finalizing the footprint.
