XC9572-10PC44C - 72-Macrocell 5V In-System CPLD | AMD
N.º da peça: XC9572-10PC44C ✗ Fim de vidaXC9572-10PC44C Visão geral
A CPLD is a programmable logic device that combines multiple logic functions into one integrated circuit. Its architecture is organized into interconnected function blocks and macrocells, allowing relatively compact logic designs to replace multiple programmable logic devices and discrete glue logic. In the broader semiconductor hierarchy, the XC9572 is a complex programmable logic device within the FPGA and CPLD category, and its in-system programming capability supports configuration without removing the package from a circuit board.
Important features include 72 macrocells, approximately 1,600 usable gates, 34 I/O pins, and a nominal 5 ns pin-to-pin logic-delay class for the broader family. The XC9572-10PC44C speed designation identifies a 10 ns-class device. Its FastFLASH configuration memory is specified for at least 10,000 program-and-erase cycles, while in-system programmability enables manufacturing, test, and field-update workflows that would be impractical with conventional fuse-programmed PLDs.
The device is divided into four function blocks, each containing 18 macrocells. This partitioning gives the designer a view of the logic architecture while retaining a unified package and pin assignment. The 5 V technology supports systems that already operate at 5 V, reducing the need for level conversion between legacy peripheral logic and the CPLD. The 44-pin PLCC package is also associated with lead-containing legacy construction, so new RoHS-restricted designs should verify compliance and sourcing requirements before production release.
Typical applications include legacy industrial control, test-and-measurement equipment, printer and peripheral controllers, board-level glue logic, embedded system interfaces, and general-purpose in-system programmable control logic. Its 34 I/O pins make it useful for designs requiring moderate I/O density rather than very high logic capacity, and its 10 ns timing class can address control, decoding, state-machine, and interface functions that do not require modern FPGA speeds.
The principal design considerations are 5 V signal compatibility, pin assignment stability, programming-tool compatibility, and legacy-package availability. Confirm the pinout and programming interface in the DS065 datasheet before schematic capture, and validate every external pull-up, pull-down, and termination resistor against the board-level interface requirements. For new production programs, verify the exact suffix, temperature grade, sourcing plan, and applicable environmental compliance.
This page combines the XC9572 architecture, pin and programming guidance, lifecycle-related sourcing considerations, and a qualified drop-in assessment. Because the XC9500 family is a legacy 5 V platform and the verified cross-reference information identifies no exact cross-vendor replacement, engineers should treat device reuse and supply planning as separate decisions rather than assume that an equivalent PLCC CPLD is electrically interchangeable.

Aplicações típicas
XC9572-10PC44C é adequado para 6 aplicaçãos: Legacy Industrial Control Logic, Test and Measurement Equipment, Printer and Peripheral Controller, Embedded System Interface Consolidation, Board-Level Programmable Control, Protocol and Bus Interface Logic.
Legacy Industrial Control Logic
The XC9572-10PC44C fits legacy 5 V industrial-control boards that use a CPLD to implement state machines, sequencing logic, interlocks, and discrete signal decoding. Its 72 macrocells and 34 I/O pins provide substantial logic capacity for distributed control functions without requiring a large FPGA. The 10 ns-class timing supports general-purpose control paths, while FastFLASH configuration permits board-level updates during manufacturing or maintenance. Because the device is specified for commercial-grade operation, verify the enclosure temperature and environmental requirements before using it in an extended industrial range.
Recomendado
Test and Measurement Equipment
The XC9572-10PC44C can consolidate timing, sequencing, trigger, and front-panel control logic in legacy test equipment. Its four 18-macrocell function blocks give designers a structured way to partition counters, state machines, and interface decoding, while 34 I/O pins support connections to sensors, relays, displays, and communication transceivers. The 5 V supply operation aligns with older measurement hardware, and in-system programming simplifies board bring-up and fixture updates. Validate acquisition-path timing separately because the CPLD's 10 ns-class delay does not determine front-end bandwidth.
Recomendado
Printer and Peripheral Controller
The XC9572-10PC44C is suitable for legacy printer, scanner, and peripheral controllers requiring deterministic glue logic between a host interface and mechanical or electromechanical subsystems. Its 72 macrocells can host command decoding, status reporting, step sequencing, and timing-state machines, while the 34 I/O pins support data, control, and feedback signals. FastFLASH configuration permits repeatable in-circuit programming during production and service. Confirm the board's legacy 5 V logic levels and the PLCC footprint before migration because pin assignment and signal-direction changes can invalidate an otherwise similar design.
Recomendado
Embedded System Interface Consolidation
The XC9572-10PC44C can replace multiple discrete logic devices in a 5 V embedded system by implementing address decoding, interrupt control, protocol translation, and peripheral multiplexing in one configurable part. Its 72 macrocells provide enough capacity for several small control functions, and the 34 I/O pins reduce the need for separate glue packages. In-system programming allows configuration to be repeated during manufacturing without soldering a dedicated programmer. The design should preserve access to the configuration pins and account for boot-time behavior, pull states, and any required pull-up resistors.
Recomendado
Board-Level Programmable Control
The XC9572-10PC44C works well as a board-level programmable controller for legacy systems that need configurable logic without a higher-performance FPGA. Typical tasks include relay interlocks, lamp and switch management, status multiplexing, and sequencing between multiple peripheral buses. The 72-macrocell device provides a larger capacity than simple GAL or small CPLD alternatives while retaining 5 V compatibility and a familiar PLCC package. Firmware updates can be implemented by reprogramming the nonvolatile FastFLASH configuration, but production procedures should include blanking, programming, and configuration-readback steps.
Recomendado
Protocol and Bus Interface Logic
The XC9572-10PC44C can implement legacy parallel-bus arbitration, address decoding, interrupt routing, and peripheral-select logic for systems operating at 5 V. Its 34 I/O pins are suitable for multiple narrow interfaces or a combination of data, control, and status signals, while the four function blocks help divide independent interface domains. The 10 ns-class device should be checked against setup, hold, and propagation requirements for every implemented path. Use controlled-impedance routing and series damping where repetitive bus transitions produce edge or ringing problems.

Notas de projeto
Assign every net from the DS065 package drawing rather than from a generic PLCC symbol because power, programming, and I/O positions must match the exact XC9572 configuration. Preserve access to the configuration interface and place any required pull-up or pull-down resistors close to their associated pins. Check the footprint against the 44-pin J-lead PLCC dimensions and solder-process requirements before releasing artwork.
Treat configuration, clock, and high-fanout nets as dedicated signal classes. Use short traces for programming signals, avoid stubs, and place termination or damping components where repeated outputs drive legacy bus loads. For timing-critical paths, analyze setup, hold, skew, and fanout against the 10 ns-class device limits; a shorter nominal delay does not automatically compensate for an inadequately conditioned board.
Do not assume that any XC9572 package suffix is interchangeable. Confirm the 44-pin PLCC body, commercial temperature requirement, 5 V supply, configuration algorithm, and exact MPN before substitution. In-system programming does not remove the need for defined boot states: specify pull states on configuration and external interface pins, and verify board behavior if the device is erased, blank, or held in reset during power-up.
Informações de conformidade
The XC9572-10PC44C is identified as RoHS non-compliant and as containing lead. REACH, halogen-free, and conflict-minerals status are not stated in the device information and therefore remain unknown.
