• Nonvolatile antifuse architecture providing deterministic timing and design security
• Hot-swap compliant I/Os supporting mixed-voltage operation without power sequencing
• Integrated boundary-scan testing capabilities in compliance with IEEE 1149.1

Applications

• High-reliability military avionics systems
• Spacecraft electronic control units
• Defense communication equipment requiring radiation tolerance alternatives
• Secure hardware implementations utilizing FuseLock technology

Procurement Notes

Verify that the ordering suffix 'M' correctly denotes the Military temperature range (-55°C to +125°C) and CQFP package type as specified in the datasheet. Confirm that the '-1' speed grade aligns with the required 215 MHz system performance specifications for your application. Ensure procurement channels are authorized for QML certified components to maintain compliance with defense quality standards.

Selection Notes

Select this component when nonvolatile configuration and high reliability are critical requirements. The A54SX32A offers a balance of logic density and pin count suitable for complex interface bridging or signal processing tasks. Consider the ceramic package for superior thermal and mechanical stability compared to plastic variants in harsh environments.

Part Context

This part belongs to the Actel HiRel SX-A family, which bridges commercial FPGA capabilities with military reliability standards. The SX-A series is known for its metal-to-metal antifuse technology, offering lower power consumption and higher security than SRAM-based FPGAs. This specific model represents the mid-range capacity option within the family.

Replacement Considerations

Direct replacements must match the 208-pin CQFP footprint and military temperature rating. Verify compatibility with existing Actel Designer software flows. Cross-reference with other HiRel SX-A devices if pin counts differ, ensuring the new part maintains the required 48,000 gate capacity and 215 MHz speed grade.
