XC9536-15PC44I - 36-Macrocell 5V CPLD | Xilinx | PLCC-44
N.º de pieza: XC9536-15PC44I ✗ Fin de vidaXC9536-15PC44I Descripción general
A CPLD, or complex programmable logic device, is a programmable-logic category positioned between simple programmable logic arrays and larger FPGAs. Its architecture combines AND-array routing with programmable OR-array logic in macrocells, producing predictable propagation delays that simplify timing analysis. The XC9536 family therefore occupies the logic-hierarchy path of CPLD, programmable logic, digital semiconductor, and integrated circuit.
Key attributes include 36 macrocells, an 800-gate equivalent rating, 34 user I/O pins, a 4.5 V to 5.5 V internal supply range, and a 15 ns maximum delay grade. The device uses Advanced CMOS 5 V Fast FLASH technology, retains its configuration in non-volatile memory, and supports at least 10,000 program and erase cycles. Multiple XC9500 devices can be programmed in parallel according to the family documentation.
The PLCC-44 J-lead package provides 44 physical positions for 34 user I/O and dedicated power, ground, configuration, and clock-related functions. Because the exact numbered pin assignment is not reproduced in the verified excerpts, pin-level connection details must be taken from the manufacturer datasheet or the official package diagram. The device is surface-mountable but is not a leadless chip carrier and cannot be replaced by a VQFP or TQFP package without a PCB redesign.
Typical applications include industrial controller glue logic, legacy peripheral interface logic, multi-copper peripheral expansion, address decoding, bus arbitration, and embedded timing control. Its 15 ns speed grade is slower than the 5 ns and 7 ns members of the XC9500 family, so designs requiring maximum operating frequency should select a faster grade if the timing budget and power requirements allow it.
Designers should preserve adequate 5 V supply decoupling, route unused I/O pins according to the device guidelines, and treat the configuration, clock, and dedicated pins as non-user I/O. Because the PLCC-44 package and programmed configuration define the final interface, any substitution must be verified for package geometry, pin functions, supply voltage, macrocell capacity, and speed grade rather than function name alone.
This page consolidates the verified distributor listings, family specifications, package information, and side-by-side alternatives with practical configuration and layout guidance. It also distinguishes true PLCC-44 drop-in choices from faster XC9500 devices packaged in VQFP or TQFP formats that would require a board redesign.

Aplicaciones típicas
XC9536-15PC44I es adecuado para 6 aplicacións: Industrial Controller Glue Logic, Legacy Peripheral Interface Expansion, Bus Address Decoding and Arbitration, Multi-Device Configuration and Expansion, Data Acquisition and Signal Conditioning, Timing and Watchdog Control.
Industrial Controller Glue Logic
The XC9536-15PC44I fits industrial controller glue logic because its 36 macrocells can implement state machines, address decoding, latch controls, and interlock logic without occupying a large FPGA. The 15 ns pin-to-pin delay provides predictable combinational timing, while the -40°C to +85°C rating suits controlled industrial equipment. Use it beside a microcontroller for peripheral selection, watchdog control, and fault-latching functions. The device is surface mounted in PLCC-44, and its non-volatile in-system configuration allows the same board to support firmware or field-option changes without a separate configuration memory. Verify all 5 V signal levels and observe the manufacturer's supply and I/O guidance.
Recomendado
Legacy Peripheral Interface Expansion
The XC9536-15PC44I is useful for expanding legacy peripheral interfaces because its 34 user I/Os can accommodate multiple chip-select, interrupt, and data-control lines. The 800-gate equivalent and 36-macrocell capacity provide sufficient resources for buffering and arbitration, and the 15 ns grade supports moderate clock-domain control logic rather than high-speed data transfer. It is particularly appropriate for retrofitting an existing industrial controller with an additional ISA-style or proprietary peripheral connector. Because the verified excerpts do not provide a complete pin table, the original XC9500 board files or manufacturer datasheet must be consulted for every routed signal.
Recomendado
Bus Address Decoding and Arbitration
The XC9536-15PC44I can implement deterministic address decoding, chip-select generation, and simple bus-arbitration priority logic for embedded systems. Its macrocell-based architecture provides consistent propagation delay, which helps prevent decode glitches from entering the timing path of slower peripherals. With 34 user I/Os, the device can connect multiple candidate addresses and arbitration request lines while remaining independent of the host processor. The 15 ns class suits legacy peripheral buses, but new designs should calculate worst-case combinational paths from the actual macrocell configuration rather than assuming a single advertised delay describes the complete implementation.
Recomendado
Multi-Device Configuration and Expansion
The XC9500 family's parallel programming capability makes the XC9536-15PC44I useful in systems that configure several CPLDs simultaneously during manufacturing or field update. The in-system programming architecture retains the design in non-volatile Fast FLASH memory and supports at least 10,000 program and erase cycles according to the verified family information. The device can therefore implement a local configuration controller, status aggregation, or revision tracking around a group of programmable logic sections. Layout should isolate programming signals from sensitive functional routing and follow the manufacturer's recommended programming-cable termination and supply sequencing instructions.
Recomendado
Data Acquisition and Signal Conditioning
The XC9536-15PC44I can handle slow signal conditioning, trigger qualification, and control sequencing around laboratory or industrial data-acquisition systems. Its 36 macrocells allow implementation of comparators, debounce circuits, sample counters, and interface state machines without burdening the main processor. The 15 ns speed is sufficient for control and supervisory paths but is not intended for high-rate parallel data processing. Keep noisy analog and switching inputs away from configuration and clock routing, and use the verified device operating range of -40°C to +85°C when planning an industrial enclosure.
Recomendado
Timing and Watchdog Control
The XC9536-15PC44I is well suited to deterministic timing-control logic such as retriggerable monostables, programmable delays, watchdog counters, and interlock sequences. The macrocell structure supports synchronous state-machine implementations with predictable delay behavior across 4.5 V to 5.5 V internal supply operation. Use it to supervise an external actuator or reset a legacy processor when a heartbeat is lost. Because the verified pin assignment is unavailable in the supplied excerpts, the design must be checked against the official PLCC-44 drawing for clock, configuration, supply, and dedicated-function assignments before layout release.

Notas de diseño
Treat the PLCC-44 footprint as non-interchangeable with the VQFP-44 and TQFP-44 XC9500 variants found in comparison listings. The J-lead target has wider body geometry and a different land pattern, so a replacement cannot be soldered directly onto the same lands. Before schematic substitution, compare the manufacturer package drawing, pin-1 orientation, lead pitch, body outline, and exposed-pad or thermal requirements. Use the official XC9500 package data rather than deriving a footprint from the J-lead designation alone.
The XC9536-15PC44I uses a 4.5 V to 5.5 V internal supply range according to the verified GlobalSpec listing. Place the manufacturer's recommended bypass capacitance at the supply and ground pins, keep high-current return paths short, and keep the CPLD away from inductors, switching-regulator power stages, and long unprotected clocks. Because exact capacitor values and current limits are not included in the supplied excerpts, use the official datasheet power and decoupling sections before releasing the layout rather than relying on generic values.
A same-package suffix change is not automatically a safe substitution. XC9536-15PC44C preserves the 15 ns grade but changes the temperature suffix, while XC9536-6PC44C provides a faster 12 ns class with a commercial suffix. Confirm the required ambient range, timing paths, configuration file compatibility, programming method, and ordering code. Faster timing can also change internal power behavior, so do not assume that a nominal timing improvement requires no revalidation of supply current or system-level power budget.
The verified excerpts identify 34 user I/O but do not reproduce the complete numbered pin table. Restore every unused input to a defined level, avoid assigning a pin to the wrong I/O bank or dedicated function, and separate configuration pins from ordinary functional routing. Because the family supports parallel programming, keep the JTAG or serial programming interface accessible and route programming signals away from high-energy switching nodes. Obtain the official PLCC-44 pin diagram before releasing any schematic or PCB artwork.
Información de cumplimiento
The verified excerpts do not state RoHS, REACH, AEC-Q100, lead-free, halogen-free, or conflict-minerals status. The industrial-temperature designation and obsolete-product lifecycle information do not establish AEC-Q100 qualification.
