A54SX32A-CQ208M

Overview

The A54SX32A-CQ208M is a HiRel SX-A Field Programmable Gate Array featuring 48,000 system gates and 174 user-programmable I/O pins. It utilizes 0.25 µ CMOS technology with metal-to-metal antifuse interconnects. The device operates at 215 MHz system performance (5.3 ns clock-to-out) in military temperature ranges (-55°C to +125°C). It supports mixed-voltage operation of 2.5 V, 3.3 V, and 5 V with 5 V input tolerance. The package is a 208-pin Ceramic Quad Flat Pack (CQFP).

Feature Summary

• Military-grade reliability with MIL-STD-883 Class B screening and QML certification.
• 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.
• Integrated Silicon Explorer II boundary-scan testing for in-system diagnostic verification.

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 suffix 'M' confirms the Military ambient temperature range (-55°C to +125°C) and CQFP package type. Confirm compliance with MIL-STD-883 Class B requirements if specified in the purchase order. Ensure design files are compatible with Actel Designer or Libero IDE software versions supporting the HiRel SX-A family.

Selection Notes

Select this component when nonvolatile configuration and high-speed deterministic timing are required in extreme environments. Compare gate density and I/O counts against the A54SX72A variant if higher capacity is needed. Verify that the 208-pin CQFP footprint matches the target PCB layout constraints and thermal management capabilities.

Part Context

This part belongs to the Actel HiRel SX-A family, designed for high-reliability applications where radiation tolerance and secure programming are critical. It serves as a robust alternative to SRAM-based FPGAs by eliminating configuration bitstreams and reducing power consumption through its antifuse architecture.

Replacement Considerations

Direct pin-compatible replacements within the same family include other speed grades of the A54SX32A series. For higher capacity needs, the A54SX72A offers increased logic resources while maintaining architectural compatibility.
