Procurement Notes

Verify component authenticity through authorized Microchip distributors or certified suppliers. Confirm that the specific suffix matches the required speed grade and package variant. Ensure proper handling procedures are followed due to moisture sensitivity classification. Review the latest Product Change Notifications for any manufacturing updates affecting this part number before finalizing procurement orders.

Selection Notes

Select this model when 36K system gates and 150 I/Os are required in a TQFP-176 footprint. Consider the -1 speed grade if higher performance than the -2 or -3 variants is needed. Verify that the 3.3V or 5.0V mixed-voltage operation aligns with the target system's power rails. Check for end-of-life status or discontinuation notices prior to design finalization.

Part Context

This component belongs to the Microchip MX FPGA family, which bridges the gap between standard FPGAs and custom ASICs. The series is characterized by its non-volatile SRAM technology, allowing instant-on functionality without external configuration memory. It targets markets demanding high reliability, such as automotive and industrial sectors, offering a cost-effective solution for medium-complexity logic designs.

Replacement Considerations

Publicly confirmed substitute part numbers for the A42MX24-1TQG176M were not identified in available documentation. Evaluate other devices within the A42MX24 series, such as the A42MX24-2TQG176M or A42MX24-3TQG176A, noting differences in speed grades. Cross-reference pinouts and electrical specifications carefully when considering alternative packages like FPQG160 or PLG84.
