Complex Programmable Logic Devices Procurement Notes

This component is listed as End-of-Life (EOL) by the manufacturer. Availability is restricted to surplus or secondary market channels. Verification of authenticity and physical condition is critical due to the discontinued status. Buyers should confirm the specific suffix details against original datasheets to ensure pin compatibility and electrical characteristics match design requirements.

Complex Programmable Logic Devices Selection Notes

Select this part when high I/O density (118 pins) is required within a CPLD architecture. Compare against the EPM7256AE series for higher macrocell counts or the EPM3032ATC44-10 for lower pin counts. Ensure the design supports the 3.3 V logic levels and that the TQFP-144 footprint fits the PCB constraints. Verify thermal management capabilities for the specified operating temperature range.

Complex Programmable Logic Devices Part Context

The EPM3256ATI144-10 is part of the MAX 3000A family, which succeeded the original MAX 3000 series. This family is characterized by its fast, predictable timing and EEPROM-based reprogrammability. It serves as a bridge between simple gate arrays and more complex FPGAs, offering deterministic performance for medium-complexity digital designs.

Complex Programmable Logic Devices Replacement Considerations

Direct pin-to-pin replacements are limited due to the EOL status. Potential functional equivalents may be found in the MAX II or MAX V families, though these require significant schematic and layout redesigns. Consult official Intel/Altera documentation for migration guides from the MAX 3000A family to newer programmable logic devices.
