Complex Programmable Logic Devices Procurement Notes

This component is identified as an End-of-Life (EOL) product. Availability is restricted to existing stock or third-party distributors. Verification of authenticity and lot traceability is critical when sourcing from non-original channels due to the discontinuation status.

Complex Programmable Logic Devices Selection Notes

Select this model for designs requiring moderate logic density (128 macrocells) with low power consumption typical of CMOS CPLDs. Ensure the design fits within the 175 MHz timing constraints. Verify that the 3V to 3.6V I/O voltage levels are compatible with the target system interfaces.

Complex Programmable Logic Devices Part Context

The XCR3128XL-7TQG144C is part of the CoolRunner XPLA3 series, which succeeded earlier XCR3000XL devices. This series was designed to offer higher performance and density while maintaining low power characteristics suitable for battery-operated and portable applications before being superseded by newer architectures.

Complex Programmable Logic Devices Replacement Considerations

Direct pin-to-pin replacements may be limited due to EOL status. Potential functional equivalents should be evaluated based on macrocell count, I/O availability, and speed grade. Consult current AMD/Xilinx portfolios for modern alternatives such as the Lattice MachXO or iCE40 families if migration is required.
