XC9572XL-5VQ44C

Overview

The AMD XC9572XL-5VQ44C is a Complex Programmable Logic Device (CPLD) belonging to the XC9500XL family. It features 72 macrocells, 34 I/O pins, and 1600 system gates organized into four logic array blocks. The device operates at a supply voltage of 3.3 V with a maximum propagation delay of 5 ns and a maximum operating frequency of 178 MHz. It utilizes Flash memory for non-volatile configuration and supports in-system programming with a minimum of 10K program/erase cycles. The component is housed in a 44-pin VQFP package.

Procurement Notes

This part number is listed as obsolete by AMD. Verification of availability should focus on surplus distributors or secondary market sources rather than direct manufacturer channels. Confirm the specific suffix 'C' denotes commercial temperature range (0°C to +70°C) and verify package integrity upon receipt.

Selection Notes

Select this component when a low pin count CPLD with Flash technology is required. Ensure the design accommodates the 3.3 V supply voltage and 5 ns timing constraints. Verify that the 44-pin VQFP footprint matches the PCB layout requirements.

Part Context

The XC9572XL-5VQ44C is part of the XC9500XL series, which succeeded the original XC9500 line. This series introduced Flash memory to eliminate the need for external EPROM programmers, enabling faster development cycles and lower power consumption compared to earlier EEPROM-based CPLDs.

Replacement Considerations

Publicly confirmed substitutes include the Microchip ATF1504ASV-15AU44, Lattice Semiconductor LC4128V-75TN100C, and Efinix T13Q100F3C4. These alternatives offer similar functionality but may differ in pin counts, speed grades, or package types.
