Procurement Notes

Verify the specific suffix against official Microchip documentation to confirm exact electrical characteristics and temperature grades. Confirm RoHS compliance status as some variants may be non-compliant. Check current product lifecycle status, as certain MX series parts are obsolete or subject to production changes. Ensure the PLCC-84 package matches the target PCB footprint requirements.

Selection Notes

Select this model when 24,000 system gates and 72 I/Os are required in an 84-pin PLCC package. Consider the -55°C to 125°C operating range for harsh environments. Verify compatibility with 3.3V and 5V supply rails. Compare gate density against A42MX09 or A42MX24 if different capacity is needed. Ensure the toolchain supports the MX Automotive family architecture.

Part Context

This component belongs to the Microchip MX Automotive FPGA family, originally developed by Actel before acquisition. The series is characterized by its anti-fuse technology and suitability for automotive-grade reliability. It serves as a bridge between discrete logic and complex SoCs, offering fixed pinout and deterministic performance for safety-critical designs.

Replacement Considerations

Publicly confirmed direct substitute part numbers are not available in the provided data. Evaluate A42MX09-PLG84A or A42MX24-PLG84A for similar packages with different gate counts. Verify functional equivalence through detailed datasheet comparison before substitution.
