XC9536-5PC44C 概述
A CPLD is a programmable-logic device that combines macrocell-based logic with nonvolatile configuration memory. In the hierarchy, the XC9500 belongs to complex programmable logic devices, which sit between basic programmable logic devices and larger FPGAs. Its principal role is to consolidate control logic, interface logic, state machines, and fixed-function glue logic into one programmable device while retaining the device after power is removed.
The XC9500 architecture described in the retrieved documentation contains two 36V18 function blocks. Key benefits include 5 ns pin-to-pin logic delays, 36 macrocells, 800 usable gates, 34 user I/O pins, and in-system programming with a minimum endurance of 10,000 program/erase cycles. It also supports parallel programming of multiple XC9500 devices, which can shorten production programming or system configuration workflows.
The verified product information identifies the XC9536 as a commercial-temperature part in a square QCCJ package with J-bend terminals. Electrical limits include maximum DC undershoot below ground of either 0.5 V or 10 mA, whichever is easier to achieve. During transitions, pins may undershoot to -2.0 V or overshoot to +7.0 V for less than 10 ns when forcing current is limited to 200 mA; external I/O voltage must not exceed VCCINT by more than 4.0 V.
Typical uses include industrial control, test equipment, legacy peripheral emulation, bus-interface control, and compact embedded-control logic. The 5 ns speed grade can suit deterministic control paths when system timing and I/O loading are verified, while the nonvolatile in-system programming architecture simplifies field updates and eliminates separate configuration loading after power-off.
Designers should preserve the specified 5 V supply tolerance and observe the stated I/O overshoot, undershoot, and external-voltage limits. PCB layout must account for the 44 J-bend terminals, programming signals, supply decoupling, and available I/O resources. Because a CPLD pin assignment and timing design depend on the selected architecture, users should verify the complete pinout and programming requirements in the manufacturer datasheet before layout release.

典型应用
XC9536-5PC44C 适用于 6 应用s: Industrial Control Logic, Legacy Peripheral Emulation, Bus Interface Control, Test and Measurement Control, Embedded System Control, Data Acquisition Control.
Industrial Control Logic
The XC9536-5PC44C fits compact industrial control logic when a design requires nonvolatile configuration, 36 macrocells, and 34 user I/O pins. Its verified 5 ns pin-to-pin delay can support deterministic control paths, while the 100 MHz counter-frequency figure provides additional timing margin for state-machine and counter designs. The 5 V supply range must remain within 4.75 V to 5.25 V. Because the retrieved data identifies a commercial temperature grade rather than an industrial range, thermal qualification and enclosure requirements must be checked separately.
推荐
Legacy Peripheral Emulation
The XC9536-5PC44C is useful for legacy peripheral emulation and board-level glue logic because its 36 macrocells can combine state machines, address decoding, and interface control in one programmable device. The verified 800 usable gates provide a defined logic budget, and the 34 user I/O pins allow a compact interface when all required pins fit. Its 5 ns grade should be checked against the worst-case board delay and external-device timing rather than assumed to guarantee system-level timing closure.
推荐
Bus Interface Control
The XC9536-5PC44C can implement bus-interface control, arbitration, and protocol glue where a small fixed architecture is preferable to an FPGA. Its 34 user I/O pins provide connections for address, data, control, and status signals, while the verified 5 ns pin-to-pin delay supports short synchronous control paths. Designers must assign pins through the supported tool flow, budget input and output timing, and observe the external I/O voltage limit of no more than VCCINT plus 4.0 V.
推荐
Test and Measurement Control
The XC9536-5PC44C can coordinate sequencers, instrument-control signals, and acquisition state logic in compact test equipment. Its 5 ns delay grade and 100 MHz counter-frequency figure make it relevant for deterministic control loops, but actual measurement accuracy depends on analog circuitry and calibration outside the CPLD. The verified commercial temperature grade means the final instrument may require additional thermal qualification. Confirm supply tolerance and configure unused pins according to the manufacturer guidance.
推荐
Embedded System Control
The XC9536-5PC44C is suitable for auxiliary control logic around a microcontroller when the required function fits 36 macrocells and 34 I/O pins. Its in-system programming allows configuration and test access without requiring a separate external programming fixture after board assembly, while nonvolatile FLASH retains the configuration when power is removed. The design should still include a defined programming path, power-up timing checks, and supply-decoupling layouts that account for the 5 V operating environment.
推荐
Data Acquisition Control
The XC9536-5PC44C can generate deterministic control signals for multiplexers, converters, counters, and data-acquisition front ends when the required timing is within its 5 ns logic-delay grade. The verified 36-macrocell and 34-I/O resources provide a compact implementation footprint for sequencing and format conversion. It does not replace high-performance analog-to-digital converters, so engineers should separate analog signal integrity, converter clocking, and digital control into distinct timing budgets before releasing the layout.

设计说明
The XC9536-5PC44C is a 5 V CPLD, and the retrieved product information specifies a 4.75 V to 5.25 V internal supply range. Design the regulator and decoupling network for that range rather than assuming a 3.3 V rail is acceptable. External I/O voltage must not exceed VCCINT by more than 4.0 V. Because current consumption, power-up sequencing, and recommended capacitor values are not supplied in the excerpts, use the manufacturer datasheet values before release rather than estimating them.
Reserve the complete 44-terminal J-lead footprint and verify every programming, power, ground, and user-I/O connection against the manufacturer pin table. The supplied excerpts do not contain a complete pin assignment, so no pin names should be inferred from package position. Use a controlled-impedance layout where external buses are involved, keep programming traces away from sensitive analog paths, and provide test access for configuration, power, and ground rails.
Treat the published 5 ns pin-to-pin delay as a device specification, not a complete system timing guarantee. Account for external-device setup and hold time, board propagation delay, package effects, output loading, and the actual clock or counter path. The verified data permits transient overshoot to +7.0 V and undershoot to -2.0 V for less than 10 ns when forcing current is limited to 200 mA; board protection and signal-source strength must preserve those limits.
Do not substitute XC9536XL-5PC44C solely because its package is described as pin-compatible. The retrieved evidence does not establish identical supply voltage, macrocell architecture, timing, programming-file compatibility, or I/O behavior. Before using it as a drop-in production alternative, compare the exact package drawing, pin table, electrical characteristics, programming tool support, and lifecycle status. The XC9536-5PC44C is also identified as RoHS non-compliant and contains lead, so procurement and environmental requirements need review.
合规信息
The retrieved distributor specification explicitly identifies the XC9536-5PC44C as RoHS non-compliant and containing lead. No verified REACH, AEC-Q100, halogen-free, or conflict-minerals statement was supplied.
