Complex Programmable Logic Devices Procurement Notes

This component is listed as End-of-Life (EOL). Availability is restricted, and it may not be sold in all regions by major distributors. Verification of current stock status and lead times from authorized suppliers is required before procurement planning.

Complex Programmable Logic Devices Selection Notes

Select this part when a high-density CPLD with EEPROM retention is needed in a BGA package. Ensure the design accommodates the 3.3V I/O levels and the specific pinout of the FBGA-256 footprint. Verify that the 172.4 MHz speed grade meets the timing requirements of the target application.

Complex Programmable Logic Devices Part Context

The EPM7256AFC256-7 is part of the MAX 7000AE series, which represents a 3.3V version of the popular MAX 7000 architecture. It offers pin compatibility with other devices in the MAX 7000 family, facilitating upgrades or replacements in existing designs requiring lower power consumption while maintaining similar functionality.

Complex Programmable Logic Devices Replacement Considerations

Direct pin-compatible substitutes within the same density and package are limited due to the EOL status. Consider reviewing the MAX 7000S or MAX 7000B families for alternative packages or speed grades, though voltage levels and pinouts may differ.
