Procurement Notes

Verify RoHS compliance status through official Microchip documentation or authorized distributors, as records indicate detailed verification is required. Confirm current availability and lifecycle status, as this specific part number may be subject to discontinuation notifications. Ensure ordering suffixes match exact package and temperature requirements.

Selection Notes

Select this model when a high-gate-count FPGA with mixed-voltage capability is required for automotive or industrial environments. Verify that the PLCC-84 package fits the PCB footprint constraints. Ensure the design utilizes the full 36,000 gate capacity efficiently, as the architecture supports 100% resource utilization.

Part Context

This component belongs to the A42MX series, which serves as a bridge between discrete logic and custom ASICs. The MX family is characterized by its non-volatile Flash technology, allowing instant-on functionality without external configuration memory. It targets applications requiring robust performance in harsh environments.

Replacement Considerations

Check for direct replacements within the A42MX series with different package options, such as PQFP variants. Verify if newer generations like the PolarFire or Igloo families offer compatible pinouts or functional equivalents for migration purposes.
