XC9572XL-5PC44C

Overview

The AMD XC9572XL-5PC44C is a Complex Programmable Logic Device (CPLD) belonging to the XC9500XL family. It features 72 macrocells, 1600 usable gates, and four logic array 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 configuration and supports In-System Programming (ISP) with a minimum of 10,000 program/erase cycles. The component is housed in a 44-pin PLCC package with J-leads and provides 34 user I/O pins. It functions within a supply voltage range of 3V to 3.6V and an operating temperature range of 0°C to 70°C.

Feature Summary

• 72 Macrocells with 1600 usable gates across 4 Logic Array Blocks
• 5 ns maximum pin-to-pin propagation delay supporting 178 MHz operation
• Flash-based non-volatile architecture with ISP capability (min 10K cycles)
• 5V tolerant I/O accepting 5V, 3.3V, and 2.5V signals

Applications

• High-performance 3.3V digital logic systems
• Replacement for legacy GALs and PALs
• Interface bridging between different voltage domains
• State machine implementation in embedded control applications

Procurement Notes

This part number is officially obsolete and no longer manufactured by AMD/Xilinx. A Product Change Notification (PCN) dated January 1, 2024, confirms end-of-life status. Verification of RoHS compliance is required as specific batches may vary; some sources indicate non-compliance while others list unaffected REACH status. Sourcing should focus on verified surplus distributors or qualified replacement components.

Selection Notes

Select this component only if the 44-pin PLCC footprint and 5 ns speed grade are strictly required. For new designs, consider modern equivalents due to obsolescence. Ensure the design accommodates the 3V–3.6V VCCIO requirement. Verify that the target PCB assembly process can handle the 44-LCC (J-Lead) package without damaging the leads during soldering.

Part Context

The XC9572XL-5PC44C is part of the XC9500XL series, which succeeded the original XC9500 line. This series introduced Flash technology, eliminating the need for external EPROM programmers and enabling faster turnaround times. The '5' suffix denotes the 5 ns speed grade, while 'PC44' specifies the 44-pin Plastic Leadless Chip Carrier package.

Replacement Considerations

Publicly confirmed substitute part numbers include ATF1504ASV-15AU44 from Microchip Technology and T13Q100F3C3 from Efinix, Inc. These alternatives offer similar functionality but may require schematic and layout modifications due to differences in pinouts and package types.
