• Supports mixed-voltage operation with PCI-compliant I/Os for 3.3V or 5V systems
• Enables up to 100% resource utilization and deterministic pin locking
• Includes unique in-system diagnostic capability via Silicon Explorer II

Applications

• High-speed controllers
• Address decoding circuits
• Peripheral bus interfaces
• DSP and co-processor functions

Procurement Notes

Verify current availability status as this part may be subject to discontinuation notices. Confirm RoHS compliance details and moisture sensitivity level (MSL 3) prior to ordering. Ensure the specific suffix matches required temperature grades and packaging formats. Cross-reference official Microchip documentation for any recent product change notifications affecting specifications or manufacturing sources.

Selection Notes

Select this model when 24K system gates and 125 I/Os are required in a PQFP-160 package. Verify that the 0°C to +70°C commercial temperature range meets application needs. Ensure design requirements align with the 4.75V to 5.25V supply voltage constraints. Consider the deterministic timing and pin fixing capabilities if replacing complex discrete logic.

Part Context

This component belongs to the A42MX series, which offers high-performance FPGA solutions for automotive and industrial applications. The MX family is known for low power consumption and fast wide-decode circuitry. It serves as a direct replacement for legacy programmable logic devices, offering higher density and easier integration through synthesis-friendly architecture.

Replacement Considerations

Check for official Microchip EOL notifications. Potential substitutes include other A42MX variants with similar gate counts but different packages, such as A42MX16-PQ208A. Verify pin compatibility and electrical characteristics before substitution.
