• Supports up to 100% resource utilization and pin fixing for direct ASIC methodology integration.
• Includes unique in-system diagnostic capability via Silicon Explorer II.
• Features fast wide-decode circuitry to ease integration and reduce design complexity.

Applications

• Automotive electronic control units requiring high reliability.
• Industrial automation systems needing deterministic timing.
• Complex digital logic replacement for custom ASICs.

Procurement Notes

Verify the exact suffix configuration against official datasheets, as variations exist within the MX family. Confirm current availability status, as specific variants may be discontinued or subject to manufacturing changes. Ensure compliance with RoHS and REACH regulations relevant to your region before procurement.

Selection Notes

Select this model when 24,000 system gates and 125 I/Os are required in a 160-pin QFP package. Consider the -3 speed grade for performance needs and the 'I' suffix for industrial temperature range. Verify power supply requirements match the 4.5V to 5.5V or 3.3V specifications provided in the electrical characteristics.

Part Context

This part belongs to the Microchip MX FPGA series, which bridges the gap between discrete logic and ASICs. The series is characterized by its non-volatile configuration memory options and robust automotive-grade offerings. The A42MX16 variant specifically targets mid-density applications requiring high pin counts and reliable performance in harsh environments.

Replacement Considerations

Check for updated revisions within the A42MX16 series. Consult Microchip documentation for any Pin-to-Pin compatible upgrades or legacy replacements if this specific speed grade is unavailable. Verify that any substitute maintains the same package footprint and voltage tolerances.
