Procurement Notes

Verify component authenticity through authorized Microchip distributors due to potential supply chain variations. Confirm RoHS compliance status as specific revisions may differ. Check for moisture sensitivity level requirements prior to soldering. Ensure packaging integrity matches storage specifications. Validate part markings against official datasheet documentation to prevent counterfeit risks.

Selection Notes

Select this model when 36,000 system gates are required for complex logic implementations. Choose the PQFP-160 package for surface-mount assembly compatibility. Opt for this variant if mixed-voltage I/O interfaces are necessary for legacy system integration. Consider the automotive temperature range if operating in harsh environments. Verify pin-locking requirements match the specific application constraints.

Part Context

This component belongs to the Microchip MX Automotive FPGA family, designed as a single-chip ASIC alternative. The series ranges from 3,000 to 54,000 system gates, offering scalable logic density. The A42MX24 variant specifically targets applications requiring high gate counts with low power consumption. It integrates fast wide-decode circuitry and configurable SRAM for flexible system architectures.

Replacement Considerations

Direct substitutes include other A42MX24 variants with different speed grades or packages, such as A42MX24-2PQG160I. Cross-reference pinouts and voltage levels when considering upgrades within the MX family. Verify that alternative packages maintain the same I/O count and functionality.
