Overview

This evaluation board features the Xilinx XC9572XL CPLD in a 44-pin VQFP package, designed for rapid prototyping of glue logic and digital interfacing. It provides access to 34 GPIO pins and includes an integrated 3.3V regulator to simplify power management on the bench.

Why Choose This Part

The board features 5V-tolerant I/O, which is increasingly rare in modern programmable logic, making it ideal for interfacing with older hardware. Its breadboard-friendly header layout and onboard power regulation allow for immediate integration into test setups without external power circuitry.

Applications

Voltage Level Translation
Utilizing 5V-tolerant I/O to interface legacy 5V CMOS/TTL logic with modern 3.3V subsystems.
Glue Logic Replacement
Consolidating multiple discrete 74-series logic gates into a single programmable chip to reduce PCB footprint.
Hardware Acceleration
Implementing high-speed state machines or custom timing controllers that offload tasks from a primary microcontroller.
Interface Bridging
Managing asynchronous data transfers between different bus protocols or custom peripheral interfaces.
