Complex Programmable Logic Devices Procurement Notes

This part number is officially discontinued and no longer manufactured by AMD/Xilinx. Verification of availability should focus on surplus or secondary market sources rather than direct manufacturer distribution. Buyers must account for the lack of RoHS compliance and potential obsolescence risks when integrating this component into new designs.

Complex Programmable Logic Devices Selection Notes

Designers requiring equivalent functionality should consider modern replacements such as the Lattice LC4128V series or Microchip ATF1504AS series. These alternatives offer similar macrocell counts and pin compatibility while ensuring current manufacturing support and regulatory compliance. Verify that the replacement package matches the target PCB footprint.

Complex Programmable Logic Devices Part Context

The XC9572-7PC84C is part of the broader XC9500 CPLD family, which was widely used for general-purpose programmable logic before being superseded by newer architectures. The '7' suffix indicates the 7.5 ns speed grade, while 'PC84C' denotes the 84-pin PLCC package and commercial temperature range. This specific variant represents a legacy solution for embedded control applications.

Complex Programmable Logic Devices Replacement Considerations

Publicly confirmed substitute part numbers include the Lattice Semiconductor LC4128V-75TN100C and the Microchip Technology ATF1504AS-10JU84. These devices are identified as similar functional replacements in distributor databases.
