XC9572XL-5PCG44C

Overview

The AMD XC9572XL-5PCG44C is a Complex Programmable Logic Device (CPLD) belonging to the XC9500XL family. It features 72 macrocells, 1600 usable gates, and four logic blocks. The device operates with a maximum propagation delay of 5 ns and supports system frequencies up to 178 MHz. It utilizes Flash memory technology for non-volatile storage and supports In-System Programming (ISP). The component is housed in a 44-pin PLCC package with J-leads and provides 34 user I/O pins. Operating voltage ranges from 3V to 3.6V, with an industrial temperature range of 0°C to 70°C.

Feature Summary

• 72 Macrocells with 1600 usable gates across four Function Blocks
• 5 ns maximum pin-to-pin logic delay supporting up to 178 MHz operation
• Flash-based non-volatile architecture enabling In-System Programming
• 5V tolerant I/O pins accepting 5V, 3.3V, and 2.5V signals

Applications

• High-performance 3.3V digital logic replacement
• Interface bridging between different voltage domains
• State machine implementation in embedded systems
• Address decoding and control logic generation

Procurement Notes

Verify RoHS compliance status as historical data indicates variations within the XC9572XL series. Confirm package integrity for the 44-LCC (J-Lead) form factor. Check for End-of-Life notices or Production Change Notices regarding manufacturing origin shifts. Ensure supply chain sources provide valid datasheets matching the specific suffix.

Selection Notes

Select this model when 72 macrocells are required with 5 ns speed grade. Compare against XC9572 variants if different package types like VQFP or TQFP are preferred. Verify I/O voltage compatibility, noting the 5V tolerance feature allows interfacing with legacy 5V logic without level shifters. Consider power consumption specifications for low-power 3.3V applications.

Part Context

This part belongs to the AMD/Xilinx XC9500XL CPLD family, which succeeded the original XC9500 series. The XL series introduced Flash technology, eliminating the need for external EPROM programmers and allowing reprogramming directly on the board. This family is designed for high-density logic applications requiring fast turnaround times and low power consumption.

Replacement Considerations

Direct pin-compatible replacements may be limited due to obsolescence. Evaluate Microchip ATF15xx series or Lattice ispLSI series for functional equivalents. Verify that substitute devices offer comparable macrocell counts, I/O configurations, and voltage tolerances before integration.
