• Communication infrastructure hardware

Procurement Notes

Verify component authenticity through authorized Microchip distributors or certified suppliers. Confirm the specific suffix 'CQ256B' matches project requirements, as variations exist within the MX family. Check for End-of-Life (EOL) status notifications via official Product Change Notices (PCNs). Ensure compliance with RoHS directives and relevant export control classifications before procurement.

Selection Notes

Select this model when a high pin count FPGA with 5V tolerance is required. Compare against other MX series variants like the A42MX36-PQG208 if a smaller footprint is acceptable. Consider the CQFP-256 package constraints regarding PCB space and thermal management. Verify that the 36K gate capacity meets design complexity without excessive overhead compared to lower-density options.

Part Context

This component belongs to the Microchip Actel MX family of FPGAs, known for non-volatile flash-based technology. The A42MX36 designation indicates a mid-range density device within this portfolio. It serves as a bridge between low-density CPLDs and high-end ASICs, offering reprogrammability with instant-on capabilities typical of flash FPGAs.

Replacement Considerations

Consult Microchip's official cross-reference tools for verified substitutes. Potential alternatives include other A42MX36 variants with different packages or speed grades. Ensure any replacement maintains compatibility with existing board layouts and software configuration files.
