A54SX72A-1CQ208B

Overview

The A54SX72A-1CQ208B 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 6,036 logic modules within a 208-pin Ceramic Quad Flat Pack (CQFP) package. The device supports mixed-voltage operation at 2.5 V, 3.3 V, and 5 V with 5 V input tolerance. It achieves a maximum internal clock frequency of 240 MHz and a pin-to-pin clock-to-out time of 5.3 ns. The component operates across a temperature range of –55°C to +125°C and complies with MIL-STD-883 Class B requirements.

Feature Summary

• Military-grade radiation tolerance and QML certification for high-reliability applications
• Nonvolatile antifuse architecture providing deterministic timing and design security
• Hot-swap compliant I/Os supporting cold-sparing and power-up/down flexibility
• Configurable I/O standards including 3.3 V/5 V PCI, LVTTL, and TTL

Applications

• Military avionics and defense systems requiring MIL-STD-883 compliance
• Spacecraft electronics utilizing QML certified components
• High-reliability industrial control systems needing hot-swap capabilities
• Prototyping platforms for RadTolerant designs

Procurement Notes

Verify that the ordering suffix matches the required speed grade and package type. Confirm MIL-STD-883 Class B screening status if specified. Check for QML certification documentation. Ensure compatibility with Actel Designer or Libero IDE software tools. Validate voltage levels for mixed-voltage I/O configurations.

Selection Notes

Select this model for applications requiring 108,000 system gates and 208 pins in a ceramic package. Choose the -1 speed grade for faster performance compared to standard grades. Ensure the design utilizes the available 213 user I/Os. Consider the 240 MHz internal clock capability for high-speed logic processing. Verify thermal management for the CQFP-208 package.

Part Context

This part belongs to the HiRel SX-A family of FPGAs, which are nonvolatile antifuse-based devices. The family includes variants like A54SX32A and A54SX72A in various packages. The A54SX72A offers higher capacity than the A54SX32A. The CQFP package provides hermetic sealing suitable for harsh environments.

Replacement Considerations

Direct replacements include other A54SX72A variants with different speed grades or packages. Cross-family migration may require redesign due to architectural differences. Verify pinout compatibility when substituting with other CQFP-208 devices.
