Complex Programmable Logic Devices Procurement Notes

Verify the specific suffix 'QI' against official datasheets, as standard listings often use 'QC'. Confirm end-of-life status and moisture sensitivity levels before procurement planning.

Complex Programmable Logic Devices Selection Notes

Select this model for designs requiring high pin counts (164 I/O) with moderate logic density. Ensure the PCB layout accommodates the 208-pin PQFP footprint and that the power supply strictly maintains the 3.0 V to 3.6 V range.

Complex Programmable Logic Devices Part Context

This part is part of the MAX 7000A series, an evolution of the original MAX 7000 CPLDs. It shares architectural similarities with variants like EPM7256AEQC208-7N but differs in package or speed grade suffixes. It serves as a robust solution for legacy system maintenance and high-reliability logic applications.

Complex Programmable Logic Devices Replacement Considerations

Direct substitutes include other EPM7256AE variants with compatible packages, such as EPM7256AEQC208-7N. Verify pin compatibility and electrical specifications before substitution.
