A54SX32A-1CQ208B

Overview

The A54SX32A-1CQ208B is a HiRel SX-A family Field Programmable Gate Array featuring 48,000 system gates and 174 user-programmable I/Os. It utilizes a 0.25 µ CMOS process with metal-to-metal antifuse technology for nonvolatile configuration. The device operates within a military temperature range of –55°C to +125°C and supports mixed-voltage operation at 2.5 V, 3.3 V, and 5 V. It achieves a maximum system performance of 215 MHz with a clock-to-out time of 5.3 ns. The component is housed in a 208-pin Ceramic Quad Flat Pack (CQFP) package and complies with MIL-STD-883 Class B requirements.

Feature Summary

• Military-grade reliability with QML certification and compliance with MIL-STD-883 Class B screening procedures.
• Nonvolatile antifuse architecture providing deterministic timing and protection against reverse engineering.
• Hot-swap compliant I/Os allowing safe insertion into active systems without power sequencing constraints.
• Integrated boundary-scan testing capabilities compliant with IEEE 1149.1 standards.

Applications

• High-reliability military avionics and defense electronics
• Spacecraft and satellite communication subsystems
• Harsh environment industrial control systems requiring radiation tolerance

Procurement Notes

Verify the specific ordering suffixes to confirm the package type, speed grade, and environmental qualification match the design requirements. Ensure that the supplier provides documentation confirming adherence to the Actel manufacturing flow and MIL-STD-883 Class B testing standards. Check for any applicable export control classifications such as ITAR or EAR restrictions before finalizing procurement.

Selection Notes

Select this component when a nonvolatile FPGA solution with high-speed performance and military temperature stability is required. The 208-pin CQFP package is suitable for applications needing extensive I/O connectivity in a hermetic ceramic form factor. Consider the 215 MHz system performance limit and the availability of dedicated clock networks for complex timing-critical designs.

Part Context

This part belongs to the HiRel SX-A family, which offers pin-compatible options across different gate counts and package styles. The A54SX32A variant provides a balance of logic density and I/O count, serving as a robust alternative to SRAM-based FPGAs in environments where power loss retention and security are critical concerns.

Replacement Considerations

Direct replacements must maintain the same pinout and functionality. Verify compatibility with existing programming tools and ensure that any substitute components also meet the required military temperature and reliability standards.
