XC9572-15PC44C - 72-Macrocell 5V CPLD | AMD PLCC
Teilenummer: XC9572-15PC44C ✗ AbgekündigtXC9572-15PC44C Übersicht
A CPLD is a programmable-logic semiconductor that combines a structured array of logic macrocells with a nonvolatile configuration memory. In the hierarchy of programmable devices, a CPLD sits between simple programmable logic arrays and more complex FPGAs: unlike mask-programmed logic, it can be configured after manufacture, while unlike most FPGAs it typically provides predictable routing and timing across its macrocell architecture. This makes the XC9500 family useful for consolidating fixed control, interface, and glue logic into one package.
The XC9572 provides four logic-element blocks, 72 macrocells, and 34 user I/O pins. Its -15 designation corresponds to a 15 ns maximum propagation-delay class, while the product data also identifies the family as supporting parallel programming of multiple XC9500 devices. In-system programmability permits configuration through the same board connectors used by the finished system, reducing assembly work compared with separately programmed nonvolatile memory.
Advanced CMOS 5 V FastFLASH technology stores the configuration nonvolatily and supports at least 10,000 program/erase cycles according to the retrieved specifications. The 5 V supply requirement and 44-pin J-lead PLCC construction distinguish this device from modern low-voltage, fine-pitch FPGA packages. That package is intended for legacy and maintenance-oriented industrial hardware rather than new compact portable products.
Typical uses include industrial control logic, legacy interface adapters, programmable test fixtures, and board-level control systems where 34 I/O pins and deterministic logic blocks are more useful than a large general-purpose FPGA. Existing XC9500 designs can also retain the same configuration ecosystem while reducing the number of separate logic devices.
The primary design consideration is package and supply continuity. The 44-pin PLCC footprint is not a modern board-standard land pattern, and the XC9500 family is legacy technology that is not recommended for new hardware designs. Engineers should preserve the existing footprint, verify timing at the required voltage and temperature, and plan configuration-cable, programming-software, and obsolescence continuity before committing to production quantities.
This page consolidates the verified device specifications, manufacturer datasheet identity, distributor availability links, legacy-family context, and qualified drop-in comparison points so engineers can distinguish genuine replacements from parts that merely share the broad CPLD category.

Typische Anwendungen
XC9572-15PC44C ist geeignet für 6 Anwendungs: Legacy industrial control, Programmable interface adapters, Legacy test and measurement fixtures, Board-level control and glue logic, Legacy communications equipment, Maintenance of installed industrial systems.
Legacy industrial control
The XC9572-15PC44C is appropriate for maintaining a 5 V industrial control board that already uses the XC9500 architecture and a 44-pin PLCC footprint. Its 72 macrocells can implement fixed sequencing, state-machine, interlock, and board-control logic, while 34 user I/O pins provide direct connections to field inputs and outputs. The -15 grade supplies a 15 ns propagation-delay class for timing analysis. In-system programming and nonvolatile FastFLASH configuration also simplify field updates. Because the XC9500 family is legacy technology and is not recommended for new designs, this use should focus on maintaining proven equipment rather than expanding an obsolete platform.
Empfohlen
Programmable interface adapters
The XC9572-15PC44C can consolidate deterministic interface and protocol-adaptation logic in one legacy 5 V system. Its 34 user I/O pins are useful for bridging parallel signals, generating control strobes, decoding status lines, and implementing test points without a large FPGA. Four logic-element blocks and 72 macrocells provide structured logic capacity, while the 15 ns speed grade supports defined timing paths. A migration or adapter board should preserve the PLCC land pattern and configuration interface. Engineers must obtain the complete pin and power data from AMD DS065 because the supplied excerpts do not identify individual PC44 pin assignments.
Empfohlen
Legacy test and measurement fixtures
The XC9572-15PC44C fits legacy test-fixture logic where repeatable pattern generation, fixture routing, and board-state control are required. The 34 user I/O pins can distribute control signals across a fixture, and the 72-macrocell structure is suitable for deterministic counters, sequencing, and conditional routing. The device's 15 ns grade provides a defined timing class, while in-system programming allows fixture logic to be updated through the assembled system. Because it operates from a 4.75 V to 5.25 V supply, it fits older 5 V test electronics, but new fixtures should compare its lifecycle limitations with current CPLD and FPGA options.
Empfohlen
Board-level control and glue logic
The XC9572-15PC44C is useful for board-level control logic that coordinates power sequencing, status indicators, resets, bus arbitration, and peripheral enables. Its 34 user I/O pins reduce the number of discrete logic packages needed in older equipment, and the 72 macrocells support multiple interacting state machines. The 15 ns speed grade makes timing budgets easier to structure within the architecture. Designers should account for the 5 V supply and PLCC footprint, validate I/O drive and timing values against AMD DS065, and preserve the configuration cable or in-system programming path. This is principally a maintenance-oriented choice because the XC9500 family is legacy technology.
Empfohlen
Legacy communications equipment
The XC9572-15PC44C can support protocol framing, buffer control, parity generation, and status sequencing in legacy communications equipment built around 5 V PLCC logic. The 34 user I/O pins suit parallel interfaces, while 72 macrocells allow several framing and control paths to share one package. Its structured macrocell architecture and 15 ns propagation-delay class can provide predictable behavior for established board revisions. A replacement board should not be released without checking the exact PC44 pinout, I/O standards, configuration pins, and timing from AMD DS065. For new communication platforms, a current CPLD or FPGA will usually provide greater logic density, supply-voltage options, and lifecycle support.
Empfohlen
Maintenance of installed industrial systems
The XC9572-15PC44C is most defensible as a maintenance component for installed systems whose schematics, layout, configuration files, and software tools already depend on the XC9500 family. Retaining the device can avoid a full board redesign when a small quantity of replacement ICs is required. The PLCC package supports surface mounting, and nonvolatile in-system programming preserves configuration after power removal. Procurement must confirm manufacturer, exact suffix, temperature grade, condition, and programming-test status because the XC9500 family is not recommended for new hardware designs. A formal obsolescence plan should remain in place even when a replacement is electrically close.

Wichtigste Unterscheidungsmerkmale
- Directly maintains the established XC9572 44-pin PLCC platform (vs. XC9572-15PCG44C)
- Verified base ordering designation for an installed design (vs. XC9572-15PC44I)
- Nonvolatile in-system reprogramming in a mature 5 V logic family (vs. Modern low-voltage CPLD or FPGA alternatives)
Designhinweise
Do not assume that an XC9572 variant with a similar package code is automatically interchangeable. The suffix may identify a different temperature grade or ordering option, and the supplied excerpts do not provide a complete PC44 pin table. Compare the exact ordering information, pin descriptions, electrical limits, configuration pins, and package drawing in AMD DS065. For a maintenance replacement, also verify that the alternative is programmed and tested with the same in-system configuration method.
Treat the 44-pin J-lead PLCC footprint as a legacy package rather than a modern land pattern. Preserve the original land geometry and component orientation when repairing an existing board, including the pin-1 marker and exposed underside geometry if present. A new PCB should not assume that a generic 44-pin PLCC library entry is sufficient; cross-check mechanical drawings, lead pitch, body outline, seating plane, and solder-process requirements against the manufacturer package data.
Calculate the 5 V rail budget from AMD DS065 before replacing this device. The verified excerpts do not provide quiescent current, dynamic current, per-pin drive current, or absolute maximum ratings, so a numerical dissipation estimate would be unreliable. Account for internal supply current, I/O loading, and any external pull-up or pull-down current, then compare total rail demand with the supply's capacity. Estimated: Pdissipation equals average input current multiplied by 5 V plus the voltage drop multiplied by I/O current.
Maintain the existing XC9500 programming cable, software, and configuration-file workflow during a repair. Although the device supports in-system programming and at least 10,000 program/erase cycles according to the retrieved specification, in-system programming does not remove the need to observe power, ground, clock, and control-pin requirements. Before field updates, test the complete configuration sequence on hardware and confirm that the programmed design behaves identically to the removed device.
