XC9572-7PC44C

Complex Programmable Logic Devices Overview

The AMD XC9572-7PC44C is a Complex Programmable Logic Device (CPLD) belonging to the XC9500 family. It features 72 macrocells and 1,600 usable system gates organized into four logic array blocks. The device operates at a maximum frequency of 55.6 MHz with a typical pin-to-pin propagation delay of 7.5 ns. It utilizes 5V FastFLASH technology for in-system programming, supporting a minimum of 10,000 program/erase cycles. The component is housed in a 44-pin PLCC package and supports commercial temperature ranges from 0°C to +70°C.

Complex Programmable Logic Devices Procurement Notes

This part number is obsolete and no longer manufactured by AMD/Xilinx. Procurement requires sourcing from third-party distributors or surplus markets. Verify RoHS compliance status as original production may not meet current environmental standards. Confirm package integrity and moisture sensitivity level handling upon receipt.

Complex Programmable Logic Devices Selection Notes

Select this component for designs requiring moderate logic density with 5V I/O compatibility. Ensure the design toolchain supports the XC9500 family architecture. Consider power consumption characteristics relative to the 5V supply voltage. Evaluate alternative packages if footprint constraints differ from the 44-PLCC form factor.

Complex Programmable Logic Devices Part Context

The XC9572-7PC44C is part of the broader XC9500 CPLD series, which established high-performance non-volatile programmable logic solutions. This specific model represents the standard 5V variant, distinct from the later XC9500XL series which introduced 3.3V operation. It serves as a legacy solution for industrial and consumer electronics applications previously reliant on discrete gate arrays.

Complex Programmable Logic Devices Replacement Considerations

Direct replacements are unavailable due to obsolescence. Potential substitutes include Microchip ATF1504AS series or Lattice LC4000 series devices, though pinouts and electrical characteristics require careful verification against the original design specifications.
