A54SX32A-CQ84M

Overview

The A54SX32A-CQ84M is a high-reliability Field Programmable Gate Array from the HiRel SX-A family, manufactured by Microchip Technology. It features 48,000 system gates and 1,800 combinatorial cells within a ceramic quad flat pack (CQFP) package with 84 pins. The device supports up to 62 user-programmable I/Os and operates at a maximum frequency of 215 MHz under military temperature conditions. It utilizes a 0.25/0.22 µ CMOS process technology and supports mixed voltage operation including 2.5 V, 3.3 V, and 5 V standards. The component is qualified to MIL-STD-883 Class B requirements.

Feature Summary

• Military-grade qualification compliant with MIL-STD-883 Class B standards for high reliability applications.
• Nonvolatile antifuse architecture providing deterministic timing and protection against reverse engineering.
• Supports hot-swap capabilities and cold-sparing without requiring specific power supply sequencing.
• Includes boundary-scan testing compliance with IEEE 1149.1 for in-system diagnostic verification.

Applications

• Military avionics systems requiring radiation tolerance and high reliability
• Spacecraft electronic subsystems and satellite communications
• Defense ground equipment and secure communication hardware

Procurement Notes

Verify that the ordering suffix CQ84M correctly identifies the Ceramic Quad Flat Pack package with 84 leads and Military ambient temperature range. Confirm Class B qualification status if required by the specific application environment. Ensure compatibility with existing Actel Designer or Libero IDE development tools for programming and configuration.

Selection Notes

Select this component when a nonvolatile FPGA solution with guaranteed performance across the full military temperature range is necessary. Consider the 48,000 gate capacity and 62 available I/Os against design complexity requirements. Evaluate the ceramic package option for environments where hermetic sealing is mandatory compared to plastic alternatives.

Part Context

This part belongs to the HiRel SX-A family of FPGAs, which are designed for demanding high-reliability environments. The family includes variants like the A54SX72A with higher gate counts. The A54SX32A specifically targets applications needing robust logic density with proven antifuse technology for long-term stability and security.

Replacement Considerations

Direct pin-compatible replacements within the same family include the A54SX32A-CQ84B for commercial grade applications. For higher capacity needs, the A54SX72A series offers increased logic resources while maintaining architectural similarities. Verify environmental specifications match before substituting.
