XC9572-10PQ100C

Overview

The XC9572-10PQ100C is a Complex Programmable Logic Device (CPLD) from the AMD XC9500 family, housed in a 100-pin PQFP package. It features 72 macrocells and 1600 usable gates organized into four Logic Array Blocks (LABs). The device supports In-System Programming (ISP) via JTAG with a minimum of 10,000 erase/program cycles. Electrical specifications include a maximum propagation delay of 10 ns and an operating frequency up to 100 MHz. It operates on a single 5V supply voltage within the range of 4.75V to 5.25V.

Feature Summary

• 72 Macrocells and 1600 Gates across 4 LABs
• In-System Programmable (ISP) via JTAG interface
• Maximum Propagation Delay: 10 ns
• Operating Frequency: Up to 100 MHz
• Single 5V Supply Voltage Operation

Applications

• General-purpose digital logic replacement
• Address decoding and bus interfacing
• State machine implementation
• Protocol conversion between different logic families

Procurement Notes

Verify component authenticity as this part number may be subject to obsolescence or limited availability from original manufacturers. Confirm package integrity and pin compatibility before integration. Check for RoHS compliance status relative to specific manufacturing dates and regional regulations.

Selection Notes

Select this model when 72 macrocells are sufficient for the design complexity. Ensure the system provides a stable 5V power rail. Compare against the XC9572XL series if lower voltage operation (2.5V/3.3V) or higher performance (7.5ns delay) is required instead.

Part Context

This component belongs to the XC9500 CPLD family, which utilizes non-volatile Flash technology. It serves as a drop-in replacement for older GALs and PALs. The '10' suffix indicates the 10 ns speed grade, while 'PQ100' denotes the Plastic Quad Flat Package with 100 pins.

Replacement Considerations

Direct pin-compatible replacements may be limited due to age. Consider the XC9572XL-10TQG100C for similar functionality with improved electrical characteristics, though package differences must be addressed. Other vendors like Microchip offer functionally similar devices such as the ATF1504 series.
