A54SX32A-CQ208B

Overview

The A54SX32A-CQ208B is a HiRel SX-A Field Programmable Gate Array featuring 48,000 system gates and 174 user-programmable I/O pins. It utilizes 0.25/0.22 µ CMOS process 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 (2.5 V, 3.3 V, 5 V) with 5 V input tolerance. The package is a 208-pin Ceramic Quad Flat Pack (CQFP), certified to MIL-STD-883 Class B standards.

Feature Summary

• MIL-STD-883 Class B certification for high reliability applications
• Hot-swap compliant I/Os with configurable power-up states
• Deterministic timing with user-controllable output slew rates
• In-system diagnostic capability via Silicon Explorer II boundary scan

Applications

• Military avionics systems requiring radiation tolerance alternatives
• Spacecraft electronic subsystems demanding QML certification
• High-reliability industrial control equipment
• Defense communication infrastructure

Procurement Notes

Verify the specific ordering suffix matches the required speed grade and package variant. Confirm that the MIL-STD-883 Class B screening requirements are explicitly stated in the purchase order. Ensure compatibility with existing design tools such as Actel Designer or Libero IDE for fuse file generation. Check for any export control classifications like ITAR or EAR restrictions applicable to this high-reliability component.

Selection Notes

Select this model when military temperature range (-55°C to +125°C) and Class B reliability are mandatory. Choose the CQFP package for hermetic sealing requirements. Consider the 48,000 gate capacity against logic module needs. Verify mixed-voltage I/O requirements match the 2.5 V/3.3 V/5 V support capabilities. Ensure design fits within the 174 available user I/O constraints.

Part Context

This component belongs to the HiRel SX-A family of antifuse FPGAs from Microchip Technology (formerly Actel). It shares architectural similarities with commercial SX-A devices but includes enhanced testing and hermetic packaging options. The family offers nonvolatile configuration without configuration bitstreams, providing inherent security against reverse engineering through FuseLock technology.

Replacement Considerations

Direct pin-compatible replacements within the same family include other speed grades of the A54SX32A series. Higher capacity options like the A54SX72A may require schematic modifications due to different I/O counts. Commercial equivalents lack the hermetic package and MIL-STD-883 screening.
