A54SX32-CQ208M

Overview

The A54SX32-CQ208M is a HiRel SX-A family Field Programmable Gate Array featuring 48,000 system gates and 174 user-programmable I/O pins. 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 I/O standards including 2.5 V, 3.3 V, and 5 V. It achieves a maximum internal clock frequency of 240 MHz and a pin-to-pin performance of 215 MHz. The component is housed in a 208-lead Ceramic Quad Flat Pack (CQFP) package.

Feature Summary

• Military-grade radiation tolerance and reliability compliant with MIL-STD-883 Class B requirements.
• Nonvolatile antifuse architecture providing deterministic timing and protection against reverse engineering.
• Hot-swap compliant I/Os allowing insertion into active systems without power sequencing constraints.
• Integrated Silicon Explorer II boundary-scan testing for in-system diagnostic verification.

Applications

• High-reliability military avionics and defense electronics
• Spacecraft command and data handling subsystems
• Harsh environment industrial control systems requiring extended temperature operation

Procurement Notes

Verify the specific ordering suffixes for QML certification status and lot traceability. Confirm that the ceramic package variant meets the required hermeticity standards for the target application environment. Ensure compatibility with Actel Designer or Libero IDE software tools for programming and verification workflows.

Selection Notes

Select this model when design complexity requires approximately 48,000 system gates within a 208-pin form factor. Choose this part over commercial variants if operation below 0°C or above 70°C is necessary. Consider the CQFP package only if hermetic sealing is mandated by environmental specifications or reliability standards.

Part Context

This component belongs to the Actel HiRel SX-A family, which bridges the gap between commercial FPGA capabilities and high-reliability military specifications. It shares architectural similarities with the broader SX-A series but includes rigorous screening processes and qualification testing defined by MIL-PRF-38535 for monolithic integrated circuits.

Replacement Considerations

Direct replacements include other HiRel SX-A devices such as the A54SX32A-1CQ208B or A54SX72A variants if higher gate counts are acceptable. Verify pinout compatibility before substituting with different speed grades or package options within the same family.
