• Deterministic, user-controllable timing with unique in-system diagnostic capability via Silicon Explorer II
• Synthesis-friendly architecture compatible with standard ASIC design methodologies
• Low power consumption CMOS technology suitable for automotive environments

Applications

• Automotive electronic control units requiring ASIC replacement
• Industrial automation logic control systems
• Consumer electronics requiring deterministic timing and low power

Procurement Notes

Verify component authenticity through authorized Microchip distributors or direct manufacturer channels. Confirm RoHS compliance status and REACH registration details prior to integration. Check for obsolescence notices or PCN updates regarding assembly site changes. Ensure proper ESD handling procedures are followed during storage and installation due to moisture sensitivity level 3 classification.

Selection Notes

Select this model when 14,000 system gates and 101 I/Os meet design requirements. Choose the PQ160M variant for surface mount assembly in 160-pin QFP packages. Verify voltage supply compatibility with 3.3V or 5V domains. Consider thermal management for industrial temperature ranges if operating near upper limits. Evaluate memory needs against the 2.5 kbit SRAM capacity.

Part Context

This part belongs to the Microchip MX FPGA family, which bridges the gap between CPLDs and high-end FPGAs. The MX series is optimized for cost-sensitive applications requiring moderate logic density and low power. It shares architectural similarities with other A42MX devices but differs in gate count and I/O configuration. The family supports flash-based non-volatile programming without external configuration memory.

Replacement Considerations

Direct substitutes within the same package may include A42MX09 variants with different speed grades or temperature ratings. Cross-family replacements might involve A40MX series devices with lower gate counts. Verify pin-to-pin compatibility and electrical characteristics before substitution. Consult Microchip documentation for specific upgrade paths or end-of-life alternatives.
