Procurement Notes

Verify component authenticity through authorized Microchip distributors or certified suppliers. Confirm lot traceability and check for relevant quality certifications such as AEC-Q100 compliance if required for automotive integration. Review datasheet revisions for any design-in updates prior to final procurement decisions.

Selection Notes

Select this model when 912 logic elements and 176 I/Os are sufficient for the target design. Ensure the 208-PQFP footprint matches the PCB layout constraints. Verify that the 5V operating voltage aligns with the system power rails and that the -40°C to +85°C temperature range meets environmental requirements.

Part Context

This part belongs to the A42MX series of flash-based FPGAs, which bridge the gap between discrete logic and custom ASICs. The series is characterized by non-volatile configuration memory and high reliability, making it suitable for legacy system upgrades and low-volume production runs where mask costs are prohibitive.

Replacement Considerations

Direct pin-to-pin replacements may include other variants in the A42MX24 family with different packages or temperature grades, such as the A42MX24-PQ208A. Verify logic capacity and I/O counts match exactly before substitution.
