XC9536-10VQ44I - 36-Macrocell 5V CPLD | AMD
N.º de pieza: XC9536-10VQ44I ✗ Fin de vidaXC9536-10VQ44I Descripción general
A CPLD is a user-programmable logic device that combines a structured architecture of AND/OR logic with electrically erasable configuration memory. In the product hierarchy, the XC9536 belongs to the CPLD family of programmable logic devices, where it provides more logic capacity and I/O than simple small PLDs while retaining a relatively simple programming model. This makes it useful for consolidating glue logic, control functions, interface conditioning, and fixed digital logic into one reconfigurable device.
Key features include 36 macrocells, approximately 800 gates, 34 I/O pins, 5 ns pin-to-pin logic delays for the higher-performance family context, and fCNT operation up to 125 MHz as described for the XC9500 5 V CPLD family. The in-system programming architecture supports at least 10,000 program and erase cycles. A 44-pin VTQFP package provides a surface-mount gull-wing footprint and supports conventional PCB assembly and inspection.
The XC9500 architecture provides a practical migration path between speed grades and package options within the same family. The XC9536XL-10VQ44I is specifically identified as pin-compatible with the 5 V-core XC9536 in the 44-pin PLCC package, while the XC9536 family also includes PC44 and CS48 package variants. Engineers should still verify programming-file compatibility, power-up behavior, I/O standards, and timing constraints whenever moving between devices or package options.
Typical uses include industrial control logic, bus interface translation, legacy peripheral emulation, programmable I/O expansion, instrumentation, and embedded system support functions. Because it is an obsolete part according to the supplied product listing, new production designs should confirm availability and lifecycle risk before committing to the XC9536-10VQ44I.
When replacing the device, prioritize exact package dimensions, pin assignment, I/O voltage, supply sequencing, and supported programmer or JTAG programming chain. The -7 and -8 speed grades offer compatibility when timing is slower, but a device with a faster propagation delay should not replace one whose original design depends on a specific timing grade without margin analysis.
This product data consolidates the verified family specifications, lifecycle information, package details, programming characteristics, and qualified drop-in comparisons. It also highlights where replacement decisions require timing, software, or PCB verification rather than relying only on the commercial description.

Aplicaciones típicas
XC9536-10VQ44I es adecuado para 6 aplicacións: Industrial Control and Automation, Legacy Bus Interface Control, Programmable I/O and Signal Conditioning, Instrumentation and Test Equipment, Data Acquisition and Control Systems, Communication Equipment Support Logic.
Industrial Control and Automation
The XC9536-10VQ44I is suitable for legacy industrial control functions that require deterministic combinational logic, 34 user I/O pins, and a maximum propagation delay of 10 ns. Its 36 macrocells and approximately 800 gates can implement interlocks, sequencing, signal conversion, and machine-control glue logic without a separate FPGA. Because the device is obsolete, an industrial retrofit should prioritize traceability and controlled-life procurement. A replacement such as the XC9536XL-10VQ44I may provide a more sustainable supply path after configuration and timing validation.
Recomendado
Legacy Bus Interface Control
The XC9536-10VQ44I can implement protocol state machines, address decoding, interrupt logic, and bus timing for legacy 5 V systems. Its 10 ns propagation-delay grade and 66.7 MHz stated maximum clock frequency are appropriate for many control-plane and peripheral-adaptation tasks where higher throughput is unnecessary. The 34 I/O pins allow the CPLD to consolidate several discrete glue-logic ICs. During replacement, verify the programmer-generated configuration file, I/O voltage, and timing against the original schematic rather than relying on package similarity alone.
Recomendado
Programmable I/O and Signal Conditioning
With 34 user I/O pins and 36 macrocells, the XC9536-10VQ44I is practical for consolidating programmable I/O buffers, polarity conversion, pulse conditioning, and interface multiplexing in older embedded equipment. Its 4.5 V to 5.5 V internal supply range supports 5 V system integration, while the nonvolatile Fast FLASH configuration permits field reprogramming. Engineers should check absolute maximum input voltage, external I/O voltage limits, and unused-pin behavior because those detailed electrical conditions were not available in the supplied search excerpts.
Recomendado
Instrumentation and Test Equipment
The XC9536-10VQ44I can implement control sequencing, status decoding, trigger logic, and peripheral multiplexing in legacy instrumentation. Its 10 ns delay grade and 66.7 MHz maximum frequency are useful for moderate-speed digital control rather than high-bandwidth signal processing. The 44-pin VTQFP package also supports conventional surface-mount assembly. For test-equipment redesigns, use the original programmer constraints and verify supply ramp, configuration timing, and I/O contention before substituting a newer XC9536XL implementation.
Recomendado
Data Acquisition and Control Systems
The XC9536-10VQ44I is appropriate for data-acquisition subsystems that need deterministic digital sequencing around sensors, converters, and communication blocks. Its 36 macrocells can organize channel enables, timing states, interrupt routing, and data-format conversion, while 34 I/O pins reduce the number of separate glue devices. Use appropriate level shifters whenever connected peripherals exceed the device's verified I/O limits. For new production, verify whether a current family member or a redesign provides better availability without changing the external connector or control-board architecture.
Recomendado
Communication Equipment Support Logic
The XC9536-10VQ44I can support legacy communications equipment with programmable baud-rate division, command decoding, framing logic, buffer arbitration, and interface multiplexing. The 800-gate device offers enough capacity for several small control functions, and the 10 ns delay grade is suitable for many peripheral and supervisory data paths. Its status as obsolete means it should not be introduced casually into new platforms. A same-package replacement must preserve the original I/O mapping, programming model, and timing margin, particularly around reset and configuration pins.

Notas de diseño
Do not treat package similarity as sufficient proof of replacement. The XC9536XL-10VQ44I is reported as pin-compatible with the 5 V-core XC9536, but configuration-file support, programming hardware, reset behavior, and timing-library equivalence should still be confirmed with the relevant AMD/Xilinx tools. Preserve the original PCB's supply decoupling, programming interface, and dedicated configuration connections until a complete hardware and programming validation is complete.
The verified internal operating range is 4.5 V to 5.5 V, so supply regulation must remain within that range during startup, programming, and normal operation. The supplied search data does not provide the complete absolute-maximum table or detailed quiescent-current values. Consequently, use the manufacturer datasheet for the exact power-pin connection, decoupling recommendations, and external I/O voltage limits rather than deriving them from the partial online specifications.
The 44-pin VTQFP uses gull-wing leads, but the supplied data does not include body dimensions, lead span, or land-pattern details. Before placing a replacement, compare the manufacturer package drawing or original PCB CAD library against the actual board, including solder-mask clearance and courtyard. This is especially important when changing between a genuine original, an XC9536XL assembly, and any newly sourced legacy stock.
Timing replacement requires margin analysis rather than speed-grade equivalence alone. A -7 or -8 ns XC9536 part has a faster maximum propagation delay than the original -10 ns grade, but faster is not always functionally interchangeable because output timing, hold requirements, and system-level race conditions may still change. Compare the complete timing paths and review any asynchronous input, reset, or configuration signal before approving the substitution.
