A54SX32-CQ208B

Overview

The A54SX32-CQ208B is a HiRel SX-A Field Programmable Gate Array featuring 48,000 system gates and 174 user-programmable I/O pins. It operates within a military temperature range of –55°C to +125°C with a standard speed grade delivering 215 MHz system performance and 5.3 ns clock-to-out timing. The device utilizes 0.25 µ CMOS technology and supports mixed-voltage operation at 2.5 V, 3.3 V, and 5 V. It is housed in a 208-pin Ceramic Quad Flat Pack (CQFP) package.

Feature Summary

• Military-grade reliability with MIL-STD-883 Class B certification and QML compliance for high-reliability applications.
• Nonvolatile antifuse architecture providing deterministic timing, low power consumption, and protection against reverse engineering.
• Hot-swap compliant I/Os allowing safe insertion into active systems without power sequencing requirements.

Applications

• Military avionics and defense electronics requiring radiation tolerance and extended temperature stability.
• Spacecraft subsystems and satellite communication equipment demanding high reliability.
• Secure hardware implementations utilizing Actel Secure Programming Technology with FuseLock.

Procurement Notes

Verify the specific ordering suffixes to confirm the package type and application temperature range. Ensure the component meets MIL-STD-883 Class B requirements if specified for your design. Check for QML certification status to guarantee compliance with Department of Defense quality standards for monolithic integrated circuits.

Selection Notes

Select this model when designing for harsh environments requiring –55°C to +125°C operational ranges. The 208-pin CQFP package is suitable for hermetic sealing needs. Consider the 48,000 gate capacity and 174 I/O count to ensure sufficient logic resources and interface flexibility for complex digital signal processing or control logic tasks.

Part Context

This component belongs to the HiRel SX-A family, which extends the commercial SX-A FPGA capabilities to meet stringent military specifications. The family utilizes antifuse technology for permanent configuration, distinguishing it from volatile SRAM-based FPGAs. It serves as a robust alternative for designs previously implemented using ASICs or CPLDs in high-reliability sectors.

Replacement Considerations

Direct pin-compatible replacements within the same family include the A54SX72A series for higher gate counts. Verify that any substitute maintains the required MIL-STD-883 Class B qualification and hermetic CQFP packaging to ensure seamless integration without board redesign.

FAQ

What is the maximum operating temperature for the A54SX32-CQ208B?

The device is tested and rated for a full military temperature range from –55°C to +125°C.

Does the A54SX32 support hot-swapping?

Yes, the I/Os are hot-swap compliant, allowing the device to be plugged into an electrically active system without degrading reliability or causing damage.

How does the antifuse architecture affect security?

The nonvolatile antifuse structure prevents reverse engineering and design theft because programmed and unprogrammed antifuses are difficult to distinguish, and there is no configuration bitstream to intercept.
