XC9572XL-5VQ64C - 72-Macrocell 3.3V CPLD 5ns | AMD Xilinx
Teilenummer: XC9572XL-5VQ64C ✓ AktivXC9572XL-5VQ64C Übersicht
A CPLD (Complex Programmable Logic Device) is a class of programmable logic that sits between simple PAL/GAL devices and large FPGAs in the programmable logic hierarchy. CPLDs use macrocell-based architecture with wide, fast AND/OR arrays that deliver deterministic, pin-to-pin timing, making them ideal for glue logic, state machines, bus interfacing, and power-up management tasks that require guaranteed timing and instant-on behavior.
Key features of the XC9572XL family include in-system programmability (ISP) with a minimum of 10,000 program/erase cycles, 3.3V internal supply operation from 3V to 3.6V, and a maximum clock frequency of 178.6 MHz. The device provides 36 inputs and 36 outputs with 52 I/O lines available to the user, organized into four dedicated logic array blocks (function blocks).
Architecturally, the XC9572XL consists of function blocks connected by a FastCONNECT switch matrix. Each macrocell includes a registers/flip-flop that can be configured as D, T, or JK type, with individual product-term control of clock, set, and reset. The 5 ns tpd version (-5 speed grade) is the fastest in the XC9572XL lineup, and the low-voltage process reduces power consumption compared to the earlier 5V XC9500 family.
Typical applications include telecom and networking line-card glue logic, industrial automation control interfaces, 5G infrastructure board management, medical instrumentation, and legacy FPGA/CPU bus-bridging designs. The instant-on, non-volatile configuration eliminates the external configuration flash required by SRAM FPGAs, simplifying power sequencing.
Design consideration: verify both a 3.3V tolerant I/O budget and the 10,000-cycle program/erase endurance limit; frequent field reprogramming beyond the endurance rating can degrade flash cells. Use the AMD iMPACT tool with the standard JTAG chain for in-system programming.

Typische Anwendungen
XC9572XL-5VQ64C ist geeignet für 6 Anwendungs: Telecom and 5G Infrastructure Glue Logic, Industrial Automation Control, Legacy System Maintenance and Redesign, Medical Instrumentation Control Logic, Embedded System Power Sequencing, Networking Board Bus Bridging.
Telecom and 5G Infrastructure Glue Logic
The XC9572XL-5VQ64C is widely used in telecom line cards and 5G infrastructure boards for address decoding, bus bridging, and board-management state machines. Its 5 ns pin-to-pin propagation delay provides deterministic timing for control signal generation between processors, PHYs, and backplane interfaces, while 52 user I/O pins handle wide parallel buses that smaller CPLDs cannot manage. The non-volatile flash configuration delivers instant-on control logic at power-up, which is essential for power-supply sequencing and slot-identification functions before host software loads. With a 178.6 MHz maximum toggle rate, the device covers standard telecom clock domains, and in-system programmability allows field updates of control logic via the onboard JTAG chain without board rework.

Industrial Automation Control
In industrial automation, the XC9572XL-5VQ64C implements sensor-interface decoding, motor-drive enable logic, and safety interlock state machines on PLC I/O boards. The 72 macrocells with individually configurable D/T/JK flip-flops allow compact implementation of multi-state sequencers, while the FastCONNECT switch matrix guarantees fixed 5 ns timing independent of routing - a critical property for deterministic interlock behavior. The commercial-grade C suffix suits 0C to +70C panel environments; for unconditioned factory-floor enclosures, the pin-identical XC9572XL-5VQ64I industrial-grade variant extends operation to -40C to +85C. Flash endurance of 10,000 cycles supports occasional field logic updates, and 3.3V operation reduces board power versus the legacy 5V XC9500 parts it commonly replaces.
Empfohlen
Legacy System Maintenance and Redesign
Many aging FPGA and CPU boards originally used the 5V XC9500 family or EPM7xxx devices for glue logic; the 3.3V XC9572XL-5VQ64C is a frequent replacement target in redesigns because XC9500XL design files port with minimal changes and the architecture retains the familiar macrocell model. With 1600 usable gates and 52 I/O, it absorbs address decoders, wait-state generators, and interrupt controllers from retired PAL/GAL arrays, consolidating multiple 22V10-class devices into one package. In-system programmability through the standard JTAG header lets service teams update logic in the field, and the non-volatile configuration eliminates configuration PROMs, simplifying bill-of-materials for long-life maintain programs in medical, defense, and industrial legacy fleets.

Medical Instrumentation Control Logic
Medical imaging and diagnostic equipment uses the XC9572XL-5VQ64C for front-panel sequencing, detector interface control, and interlock monitoring. Deterministic 5 ns pin-to-pin timing ensures that safety interlocks and detector-enable signals behave identically on every board, an important property for validation and regulatory documentation. The 52 user I/O pins interface parallel detector buses and relay drivers, and the non-volatile flash configuration means calibration state machines are active immediately at power-on without waiting for configuration loading. The device's 3V to 3.6V supply integrates cleanly with 3.3V DSP and FPGA subsystems, and the JTAG ISP path supports field firmware upgrades of the control logic during instrument service without desoldering.

Embedded System Power Sequencing
Multi-rail embedded systems use the XC9572XL-5VQ64C to sequence and monitor power supplies: the CPLD watches regulator power-good outputs, drives enable pins in the required order, and asserts system resets. Instant-on flash configuration is essential here - the sequencing logic must be alive before any processor boots, which SRAM FPGAs cannot do without external configuration. The 72 macrocells implement sequencing state machines plus brown-out and fault latching with individually controlled set/reset product terms, while the 178.6 MHz toggle capability handles fast fault sampling. Deterministic 5 ns timing guarantees monotonic enable transitions, and in-system programmability lets hardware teams revise rail order late in bring-up by reflashing the CPLD through its JTAG header.
Empfohlen
Networking Board Bus Bridging
Enterprise networking and storage controllers use the XC9572XL-5VQ64C to bridge legacy parallel buses to modern subsystems: PCI-era address/data latching, byte-lane control, and card-select decoding. The device's 36 inputs and 36 outputs handle wide 32-bit buses with control strobes, and the fixed 5 ns pin-to-pin delay simplifies setup/hold budget calculations across long backplane traces. Four function blocks with 72 macrocells absorb multiple decoder chips into a single 64-TQFP footprint, cutting board area and component count. Because the flash configuration is non-volatile, bus logic is active at first clock edge after power-up, and design changes - such as adding a slot ID - are made by reprogramming via JTAG, preserving the certified PCB layout.

Wichtigste Unterscheidungsmerkmale
- Fastest speed grade in the VQ64 XC9572XL family (vs. XC9572XL-10VQ64C)
- Green RoHS package option available in same footprint (vs. XC9572XL-5VQG64C)
- Instant-on non-volatile flash configuration (vs. SRAM FPGA alternatives (e.g., XC2C64A needs no flash either, but larger FPGAs do))
Designhinweise
Decouple each VCCINT pin of the XC9572XL-5VQ64C with a 0.1uF ceramic capacitor placed within 5 mm of the pin, plus one 4.7uF to 10uF bulk capacitor per supply rail. The internal supply must stay within 3V to 3.6V; CPLD dynamic current spikes when many macrocells toggle simultaneously at the 178.6 MHz maximum rate, so size the supply rail with margin. Estimate: at typical XC9500XL ICC levels for a 72-macrocell part at moderate toggle rates, total dissipation remains well under the TQFP-64 thermal capability, but verify against the ICC tables in AMD data sheet DS057 for your actual design.
The 64-TQFP (VQ64) footprint is shared across all XC9572XL speed grades and the green-package XC9572XL-5VQG64C variant, so lay out the board once and qualify multiple suffixes for supply resilience. Route the 4-wire JTAG chain (TCK, TMS, TDI, TDO) with a 2x5 or 2x7 header and 10 kohm pull-ups on TMS and TDI so future in-system reprogramming is possible even if the header is unpopulated in production. Keep JTAG traces short and keep the TCK clock line away from switching regulator nodes to avoid spurious TCK edges during programming.
The XC9572XL is a 3.3V device - do not directly drive its I/O with 5V logic levels inherited from XC9500 designs; use level shifters or current-limiting series resistors per AMD guidance in DS057. Track program/erase cycles against the 10,000-cycle endurance minimum in production programming jigs. When substituting the -7 or -10 speed grade, re-run static timing analysis because tpd doubles and setup/hold windows shift. Finally, confirm the correct device type is selected in iMPACT - programming a VQG64C JTAG ID mismatch will fail silently on some cable configurations.
The 5 ns pin-to-pin propagation delay of the -5 grade means output edges are fast enough to require attention on long traces. Add 22 ohm to 33 ohm series termination resistors on outputs driving ribbon cables, backplane stubs, or traces longer than roughly 10 cm (estimated using a 1.5 ns/ns driver edge assumption), and maintain a solid ground return under high-toggle I/O banks. Unused I/O pins should be driven to a defined logic level by the design constraints rather than left floating, reducing ground bounce and uncontrolled current in the output stage.
Compliance-Informationen
The green-package variant XC9572XL-5VQG64C carries AMD's halogen-free green package designation. Compliance status of the standard XC9572XL-5VQ64C suffix should be confirmed against the AMD product page before export-controlled or regulated deployments.
