Procurement Notes

Verify component authenticity through authorized Microchip distributors. Confirm that the specific ordering suffix matches the required speed grade and temperature rating. Ensure proper handling procedures are followed due to moisture sensitivity classification. Review the latest datasheet revisions for any updates regarding pin assignments or electrical characteristics before finalizing procurement orders.

Selection Notes

Select this model when high gate density and robust security features are required. The antifuse technology ensures permanent programming suitable for mass production. Verify that the FBGA-256 package fits the PCB layout constraints. Consider the thermal management requirements associated with the specified operating temperature range and voltage specifications during the design phase.

Part Context

This component belongs to the Actel SX-A FPGA family, which utilizes CMOS antifuse technology. The SX-A series is designed for applications demanding low power consumption and high performance. The A54SX72A variant represents the highest capacity within the standard SX-A lineup, offering extensive logic resources for complex digital designs.

Replacement Considerations

Direct replacements include other devices within the SX-A family such as the A54SX32A or A54SX16A, though these offer lower gate counts. Cross-family migration to newer Microchip FPGA architectures may require significant design adaptation. Verify pin compatibility and software toolchain support before substituting.
