A54SX72A-CQ208B

Overview

The A54SX72A-CQ208B is a HiRel SX-A family Field Programmable Gate Array (FPGA) manufactured by Microchip Technology. It features 108,000 system gates and 6,036 combinatorial cells within a 208-pin Ceramic Quad Flat Pack (CQFP). The device supports mixed-voltage operation at 2.5 V, 3.3 V, and 5 V with 5 V input tolerance. It achieves 215 MHz system performance and 240 MHz internal performance in military temperature ranges (-55°C to +125°C), with a clock-to-out time of 6.7 ns. The architecture utilizes metal-to-metal antifuse technology for nonvolatile configuration.

Feature Summary

• Military-grade reliability with MIL-STD-883 Class B certification and QML compliance.
• Nonvolatile antifuse architecture providing deterministic timing and protection against reverse engineering.
• Hot-swap compliant I/Os allowing safe insertion into active systems without power sequencing requirements.
• Configurable I/O standards supporting 3.3 V/5 V PCI, LVTTL, and TTL with individual slew rate control.

Applications

• High-reliability military avionics and defense systems
• Spacecraft and satellite electronic subsystems
• Harsh environment industrial control applications

Procurement Notes

Verify the specific ordering suffixes to ensure the package type, speed grade, and temperature range match the design requirements. Confirm that the component meets the necessary export control classifications and quality management standards required for high-reliability procurement channels.

Selection Notes

Select this device when a nonvolatile FPGA solution with guaranteed military temperature performance is required. Ensure the design utilizes the available global and quadrant clocks effectively. Verify that the 208-pin CQFP package fits the mechanical constraints and that the pin count accommodates the necessary I/O configurations.

Part Context

This component belongs to the Actel HiRel SX-A family, designed for high-reliability applications requiring radiation tolerance and robust performance. It serves as a bridge between commercial FPGA capabilities and the stringent demands of military and aerospace environments, offering a single-chip solution for complex logic integration.

Replacement Considerations

Direct replacements must maintain the same gate density, package type, and military qualification. Check for updated datasheet revisions or PCNs from the manufacturer. Alternative packages within the same device family may be considered if pin compatibility allows.
