• Features hot-swap compliant I/Os allowing safe insertion into active systems without power sequencing requirements.
• Includes dedicated quadrant clock networks for efficient signal distribution across the die.
• Provides boundary-scan testing capabilities compliant with IEEE Standard 1149.1.

Applications

• High-performance digital logic integration requiring deterministic timing.
• Systems necessitating hot-swappable interface capabilities.
• Industrial control applications requiring robust I/O flexibility and wide voltage support.

Procurement Notes

Verify component authenticity through authorized Microchip distributors or certified agents. Confirm that the specific ordering suffix matches the required speed grade, package type, and temperature rating. Request official datasheets and RoHS compliance documentation prior to finalizing acquisition to ensure alignment with project specifications.

Selection Notes

Select this model when designs require high gate density with flexible mixed-voltage I/O standards. Ensure the application benefits from nonvolatile antifuse technology for permanent configuration. Verify that the 256-pin FBGA footprint fits the PCB layout constraints and that the 172 MHz performance meets the system timing requirements.

Part Context

This component belongs to the Actel SX-A family of FPGAs, which utilizes metal-to-metal programmable antifuse technology. The family offers a sea-of-modules architecture designed for high performance and low power consumption. The A54SX72A represents the highest capacity tier within this specific series, providing extensive logic resources for complex digital designs.

Replacement Considerations

Consult the official SX-A Family datasheet for verified cross-reference part numbers. Substitutions must match the exact pin count, package dimensions, and electrical characteristics. Verify compatibility with existing design tools and programming hardware before implementation.
