Procurement Notes

Verify the specific ordering suffix against the manufacturer's current datasheet to confirm package type, speed grade, and temperature rating. Confirm RoHS compliance status and packaging details directly with authorized distributors or the manufacturer before placing orders.

Selection Notes

Select this model for designs requiring high gate density with nonvolatile configuration. Ensure the design accounts for the specific routing resources and clock network availability inherent to the A54SX72A architecture compared to smaller devices in the SX-A family.

Part Context

This part belongs to the Actel SX-A family of FPGAs, which are characterized by their metal-to-metal programmable antifuse interconnect technology. This architecture provides permanent connections upon programming, offering high reliability and security against reverse engineering compared to volatile SRAM-based FPGAs.

Replacement Considerations

Direct functional replacements within the same package and pinout may include other speed grades of the A54SX72A series, such as the -1 or standard speed variants, provided timing constraints allow. Cross-family migration requires schematic and code verification.
