A54SX72A-CQ208M

Overview

The A54SX72A-CQ208M is a high-reliability Field Programmable Gate Array from the HiRel SX-A family, manufactured by Microchip Technology. It features 108,000 system gates and supports up to 213 user-programmable I/Os within a 208-pin Ceramic Quad Flat Pack (CQFP) package. The device operates across a military temperature range of –55°C to +125°C with a standard speed grade achieving 5.3 ns clock-to-out timing. It utilizes 0.25 µm CMOS process technology and supports mixed-voltage operation at 2.5 V, 3.3 V, and 5 V.

Feature Summary

• Military-grade reliability compliant with MIL-STD-883 Class B standards
• Nonvolatile antifuse architecture providing deterministic performance and design security
• Hot-swap compliant I/Os allowing safe insertion into active systems
• Integrated Boundary-Scan Testing (BST) for in-system verification

Applications

• High-reliability military avionics systems
• Space-grade electronic equipment requiring radiation tolerance
• Defense communication infrastructure
• Industrial control systems demanding extended temperature stability

Procurement Notes

Verify component authenticity through authorized Microchip distributors or certified agents. Confirm that the specific lot meets MIL-STD-883 Class B requirements. Ensure proper handling procedures are followed due to the ceramic packaging and sensitivity to electrostatic discharge during installation.

Selection Notes

Select this model when designing for environments requiring –55°C to +125°C operational ranges. The CQFP package is suitable for applications needing hermetic sealing. Consider the 108,000 gate capacity for complex logic integration replacing multiple CPLDs or ASICs in space-constrained designs.

Part Context

This component belongs to the Actel HiRel SX-A family, which was acquired by Microchip Technology. The series is characterized by its metal-to-metal antifuse technology, offering nonvolatile configuration without the need for external configuration memory. It serves as a bridge between commercial FPGA capabilities and stringent military quality standards.

Replacement Considerations

Direct pin-compatible replacements within the same family include the A54SX32A-CQ208M, though it offers lower gate density. Cross-family migration to other Actel or Microchip FPGA lines requires schematic and software re-verification.
