Procurement Notes

Verify current availability status as discontinuation notices may apply to specific suffixes within the A42MX36 series. Confirm that the PBGA-272 package matches the target PCB footprint. Ensure design tools support the specific MX family generation. Check for any recent Product Change Notifications regarding assembly sites or material composition updates prior to final procurement authorization.

Selection Notes

Select this model when 54,000 system gates and 272 pins are required for high-performance logic applications. The BG272 package suits designs needing extensive I/O density on a compact footprint. Verify voltage requirements align with the mixed 3.3V/5.0V I/O specification. Consider thermal management capabilities inherent to the BGA form factor during board layout planning.

Part Context

This component belongs to the Actel/Microchip MX FPGA family, known for non-volatile flash-based technology. The A42MX36 variant represents the highest capacity tier within this specific generation, offering significant logic resources compared to lower-gate-count siblings like the A42MX16 or A42MX24. It serves as a bridge between standard PLDs and full-scale FPGAs.

Replacement Considerations

Direct pin-to-pin replacements are limited due to the specific gate count and package combination. Evaluate A42MX36 variants with different packages (e.g., PQFP, CQFP) if footprint flexibility exists. Cross-family migration to newer Microchip PolarFire or SmartFusion series may be necessary for long-term supply assurance.
