XC9572XL-7PCG44C

Overview

The XC9572XL-7PCG44C is a Complex Programmable Logic Device (CPLD) from the AMD/Xilinx XC9500XL family, housed in a 44-pin Plastic Quad Flatpack (PQCC) package. It features 72 macrocells and 1,600 usable gates organized into four Logic Array Blocks (LABs). The device operates at a maximum system frequency of 125 MHz with a typical propagation delay of 7.5 ns. It utilizes Flash memory technology for non-volatile configuration, supporting system-in-programmability with over 10,000 program/erase cycles. The component supports 3.3V operation with 5V-tolerant I/O pins.

Feature Summary

• Flash-based non-volatile architecture enabling System-In-Programmability (SIP)
• 72 macrocells with 1,600 usable gates across four LABs
• Maximum operating frequency of 125 MHz with 7.5 ns propagation delay
• 5V tolerant I/O pins compatible with 5V, 3.3V, and 2.5V signals

Applications

• High-performance digital logic control systems
• Interface bridging between different voltage domains
• General-purpose programmable logic in computing systems

Procurement Notes

Verify current availability status as this part number may be subject to limited supply or obsolescence. Confirm package integrity and moisture sensitivity level handling requirements prior to assembly. Ensure compatibility with existing design tools and programming hardware for Flash-based CPLDs.

Selection Notes

Select this component when a small footprint 44-pin package is required alongside moderate logic density. The 7.5 ns speed grade offers a balance between performance and power consumption for 3.3V applications. Consider the 5V tolerance feature if interfacing with legacy 5V logic circuits without additional level shifting components.

Part Context

This device belongs to the XC9500XL series, an evolution of the XC9500 family featuring Flash technology instead of EEPROM. The XL series provides higher performance and lower power consumption while maintaining pin-to-pin compatibility with previous generations. The PQCC44 package is one of several available form factors for the 72-macrocell variant.

Replacement Considerations

Direct replacements within the same family include XC9572XL-5VQ44C or XC9572XL-7VQ44C for VQFP packages. Cross-vendor equivalents such as Microchip ATF1504ASV-15AU44 are noted as similar alternatives but require verification of pinout and electrical characteristics.
