Procurement Notes

Verify the specific suffix against official Microchip documentation to confirm package material and temperature rating. Confirm current availability status as legacy components may have limited supply. Ensure compliance with RoHS and REACH regulations relevant to the manufacturing date code. Cross-reference the part number with the latest datasheet revision to validate pinout and electrical specifications before procurement.

Selection Notes

Select this model when high gate density and radiation tolerance are required in a ceramic package. Compare CLB count and SRAM capacity against application requirements. Verify voltage levels match the target system's I/O standards. Consider thermal management needs for the CQFP-256 package in enclosed industrial environments.

Part Context

This component belongs to the Microchip A42MX36 family, which offers scalable FPGA solutions ranging from 9,000 to 54,000 gates. The MX series is distinguished by its flash-based technology and robust packaging options suitable for harsh environments. It serves as a direct upgrade path for older EEPROM-based PLDs in critical infrastructure applications.

Replacement Considerations

Check for updated revisions within the A42MX36 series that may offer improved availability. Evaluate equivalent devices from other manufacturers if lead times are critical, ensuring functional and pin compatibility. Consult Microchip PCNs for any assembly site changes or software tool updates affecting this part number.
