A54SX32A-1CQ84M

Overview

The A54SX32A-1CQ84M is a high-reliability Field Programmable Gate Array from the HiRel SX-A family, manufactured by Microchip Technology. It provides 48,000 system gates and supports up to 62 user-programmable I/O pins within an 84-pin Ceramic Quad Flat Pack (CQFP) package. The device operates at a standard speed grade of 215 MHz with a clock-to-out time of 5.3 ns. It utilizes a 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 military ambient temperature ranges spanning from –55°C to +125°C.

Feature Summary

• Military-grade reliability with MIL-STD-883 Class B screening and QML certification
• Nonvolatile antifuse architecture providing deterministic timing and design security
• Hot-swap compliant I/Os supporting cold-sparing applications without power sequencing
• Integrated in-system diagnostic capabilities via Silicon Explorer II boundary scan

Applications

• High-reliability military avionics systems
• Spacecraft electronic subsystems
• Defense communication equipment requiring radiation tolerance alternatives
• Industrial control systems demanding extended temperature stability

Procurement Notes

Verify that the specific ordering suffix corresponds to the required speed grade and package configuration. Confirm compliance with export control regulations such as ITAR or EAR prior to acquisition. Ensure that the procurement channel is authorized to handle components subject to strict quality management procedures defined by MIL-PRF-38535 standards.

Selection Notes

Select this component when nonvolatile logic resources are required to eliminate configuration bitstream vulnerabilities. The CQFP package is suitable for hermetic sealing requirements in harsh environments. Evaluate the 48,000 gate capacity against complex logic designs needing up to 1,080 dedicated flip-flops and mixed-voltage I/O flexibility.

Part Context

This part belongs to the Actel HiRel SX-A FPGA family, which bridges commercial performance with military durability. The SX-A series utilizes antifuse technology to offer superior protection against reverse engineering compared to SRAM-based FPGAs. The A54SX32A variant serves as a mid-range solution within the portfolio, balancing gate density with low power consumption.

Replacement Considerations

Direct pin-compatible replacements include other variants within the A54SX32A series, such as different speed grades or package options like the A54SX32A-CQ208M. Verify that any substitute maintains the same Class B qualification level and hermetic packaging specifications.
