Procurement Notes

Verify component authenticity through authorized distributors as this part number may be subject to obsolescence notices. Confirm RoHS compliance status and moisture sensitivity level (MSL 3) prior to assembly planning. Check for available replacement options such as the XC2C256 series if current stock is limited.

Selection Notes

Select this model when design requirements specify 256 macrocells with high-speed performance under 7ns delay. Ensure the PCB layout accommodates the FTBGA-256 package dimensions. Verify that the power supply provides stable 3.3V operation within the specified 3V to 3.6V range for optimal timing performance.

Part Context

This CPLD is part of the CoolRunner XPLA3 family, which bridges the gap between simple PLDs and complex FPGAs. It utilizes AMD's advanced EEPROM process technology to provide non-volatile configuration without external memory devices, offering a cost-effective solution for moderate logic density applications.

Replacement Considerations

The XC2C256-7FTG256C is listed as a similar alternative from AMD. Lattice Semiconductor LC4256V series devices may also serve as functional replacements depending on specific pinout and speed grade requirements.
