A54SX32A-1CQ84B

Overview

The A54SX32A-1CQ84B is a high-reliability Field Programmable Gate Array from the HiRel SX-A family, manufactured by Microchip Technology. It provides 48,000 system gates and 1,800 combinatorial cells within an 84-pin Ceramic Quad Flat Pack (CQFP) package. The device operates at a standard speed grade of 215 MHz with a clock-to-out time of 5.3 ns under military temperature conditions ranging from –55°C to +125°C. It supports mixed-voltage I/O standards including 2.5 V, 3.3 V, and 5 V PCI, LVTTL, and TTL configurations.

Feature Summary

• Military-grade reliability with MIL-STD-883 Class B certification and QML compliance for harsh environments
• Nonvolatile antifuse architecture providing deterministic timing and protection against design theft
• Hot-swap compliant I/Os allowing safe insertion into active systems without power sequencing requirements
• Integrated in-system diagnostic capabilities via Silicon Explorer II boundary scan testing

Applications

• High-reliability military avionics and defense electronics
• Spacecraft and satellite communication subsystems
• Industrial control systems requiring extended temperature operation
• Secure hardware prototyping for radiation-tolerant designs

Procurement Notes

Verify that the specific ordering suffix matches the required speed grade and environmental qualification. Confirm the package type corresponds to the intended board layout. Ensure compliance with export regulations such as ITAR or EAR if applicable to the destination country. Check for any recent product change notifications regarding manufacturing sources or material composition updates.

Selection Notes

Select this component when nonvolatile configuration and high-speed performance are critical for military applications. Consider the 84-pin CQFP package constraints for pin count and thermal management. Evaluate the need for Class B screening versus standard military temperature testing based on mission requirements. Compare resource utilization against the A54SX72A variant if higher gate counts are anticipated.

Part Context

This part belongs to the Actel HiRel SX-A family of FPGAs, which utilizes antifuse technology for permanent programming. The A54SX32A designation indicates 48,000 system gates, distinguishing it from the larger A54SX72A model. The CQFP package offers hermetic sealing suitable for aerospace and defense environments where moisture resistance is essential.

Replacement Considerations

Direct replacements must maintain the same antifuse architecture and pinout compatibility. Verify that alternative devices support the required 215 MHz performance at –55°C to +125°C. Ensure the substitute offers equivalent MIL-STD-883 Class B screening if high reliability is mandated.
