Procurement Notes

Verify component authenticity through authorized Microchip distributors or direct manufacturer channels. Confirm RoHS compliance status and specific suffix designations against official datasheets. Check for End-of-Life notifications or discontinuance notices prior to procurement. Ensure supply chain documentation matches the exact part number variant.

Selection Notes

Select this model for designs requiring fixed pin assignments and deterministic timing in automotive or industrial settings. Compare gate counts and I/O availability against other A42MX series variants. Verify voltage requirements match the target system's 3.3V or 5.0V rails. Consider package constraints when choosing between PQFP and PLCC options.

Part Context

This component belongs to the Actel/Microchip MX family of flash-based FPGAs. These devices are known for non-volatile configuration and radiation tolerance. The A42MX24 variant offers mid-range capacity within the family, bridging lower-density parts like the A40MX02 and higher-density options like the A42MX54.

Replacement Considerations

Direct replacements may include other A42MX24 speed grades or package variants such as A42MX24-PL84I or A42MX24-PQ208A. Verify pin compatibility and timing specifications before substitution. Cross-reference with newer Microchip FPGA families if long-term availability is required.
