A54SX72A-CQ208

Overview

The A54SX72A-CQ208 is a military-grade 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/O pins within a 208-pin Ceramic Quad Flat Pack (CQFP) package. The device operates at a system performance of 215 MHz with a clock-to-out delay of 6.7 ns. It utilizes 0.25/0.22 µ CMOS process technology and supports mixed-voltage operation at 2.5 V, 3.3 V, and 5 V. The component is qualified for the full military temperature range of –55°C to +125°C.

Feature Summary

• Military-qualified nonvolatile antifuse architecture providing deterministic timing and high reliability
• Supports hot-swap compliant I/Os and cold-sparing capability without voltage sequencing requirements
• Includes dedicated in-system diagnostic and verification capabilities via Silicon Explorer II boundary-scan testing

Applications

• High-reliability military electronic systems requiring radiation tolerance alternatives
• Spacecraft avionics and satellite communication subsystems
• Defense ground-based radar and signal processing equipment

Procurement Notes

Verify that the ordering suffix matches the required speed grade and package variant. Confirm that the supplier provides traceability documentation consistent with MIL-PRF-38535 QML standards. Ensure the component lot meets the specified environmental screening requirements for military applications before integration into final assemblies.

Selection Notes

Select this model when 108,000 system gates are required within a 208-pin ceramic footprint. Choose this part over commercial variants if operation within the –55°C to +125°C temperature range is mandatory. Consider the CQFP package for applications requiring hermetic sealing and resistance to harsh environmental conditions compared to plastic packages.

Part Context

This component belongs to the Actel HiRel SX-A family of FPGAs, which are designed for high-reliability applications. The family includes lower-density devices such as the A54SX32A. The A54SX72A represents the higher capacity tier within the 208-pin form factor, offering increased logic resources while maintaining pin compatibility with other devices in the same package series.

Replacement Considerations

Direct replacements include other A54SX72A variants with different speed grades or package types, such as A54SX72A-1CQ208M. Verify that any substitute maintains the same 208-pin CQFP footprint and military temperature qualification to ensure mechanical and thermal compatibility.
