Complex Programmable Logic Devices Procurement Notes

Verify the specific suffix 'ETA' against official manufacturer documentation to confirm package type and speed grade accuracy. Ensure compatibility with existing PCB footprints and verify that the 3.3V operating voltage aligns with system power rails. Confirm availability status as older generation CPLDs may have limited production runs or obsolescence notices.

Complex Programmable Logic Devices Selection Notes

Select this component when replacing legacy 5V MAX 7000S designs with a 3.3V requirement while maintaining pin compatibility. Consider the 128 macrocell capacity for moderate complexity logic functions. Evaluate the 10ns speed grade against system clock requirements. Verify that the TQFP-144 package fits the mechanical constraints of the target enclosure.

Complex Programmable Logic Devices Part Context

This part belongs to the Altera MAX 7000A family, which bridges the gap between simple PLDs and complex FPGAs. The family is characterized by its EEPROM-based non-volatility and fast in-system programming capabilities. It serves as a robust solution for glue logic consolidation in mixed-voltage environments.

Complex Programmable Logic Devices Replacement Considerations

Check for direct pin-compatible upgrades within the MAX 7000A series, such as higher density variants like the EPM7256A. Verify electrical characteristics against similar devices from other manufacturers if sourcing alternatives.
