• Co-processor functions

Procurement Notes

Verify end-of-life status and last-time buy dates before procurement. Confirm RoHS compliance details as some sources indicate non-compliance while others list detailed compliance. Check for PCN updates regarding assembly site changes or software modifications. Ensure availability through authorized distributors due to potential discontinuation risks associated with legacy FPGA families.

Selection Notes

Select this model for designs requiring 14,000 system gates in a PLCC-84 package. Verify thermal requirements against the -55°C to +125°C operating range. Ensure power supply constraints align with the 4.5 V to 5.5 V specification. Consider pin count limitations of 72 I/Os for interface requirements. Evaluate migration paths if newer Microchip FPGA families are preferred for long-term support.

Part Context

The A42MX09-PLG84M belongs to the Microsemi/Microchip 40MX and 42MX FPGA families. These devices are designed as single-chip solutions to consolidate logic previously implemented in multiple PALs, CPLDs, and FPGAs. The MX series emphasizes deterministic timing and ease of integration for automotive and industrial applications.
