A54SX32A-CQ208

Overview

The A54SX32A-CQ208 is a military-grade Field Programmable Gate Array from the HiRel SX-A family, manufactured by Microchip Technology. It features 48,000 system gates and supports up to 174 user-programmable I/O pins within a 208-pin Ceramic Quad Flat Pack (CQFP) package. The device operates across a temperature range of –55°C to +125°C and utilizes 0.25/0.22 µ CMOS process technology. Key electrical specifications include a maximum internal clock frequency of 240 MHz and a pin-to-pin clock-to-out delay of 5.3 ns. It supports mixed-voltage operation at 2.5 V, 3.3 V, and 5 V with 5 V input tolerance.

Feature Summary

• Military-grade reliability with QML certification and MIL-STD-883 Class B compliance.
• Nonvolatile antifuse architecture providing deterministic timing and protection against reverse engineering.
• Hot-swap compliant I/Os allowing 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 requiring radiation tolerance alternatives

Procurement Notes

Verify that the specific part number suffix corresponds to the required speed grade and package variant. Confirm that the supplier provides appropriate documentation for QML certification and MIL-STD-883 Class B testing results. Ensure handling procedures account for the ceramic package type and moisture sensitivity levels defined in the datasheet.

Selection Notes

Select this component when designing for environments requiring extended temperature ranges and high reliability. Consider the 48,000 gate capacity and 174 I/O limit for logic density requirements. Evaluate the need for hot-swap capabilities and mixed-voltage I/O support compared to commercial FPGA alternatives.

Part Context

This device belongs to the HiRel SX-A family of nonvolatile FPGAs, which are designed for high-performance applications in military and space sectors. It serves as a radiation-tolerant alternative to SRAM-based FPGAs, offering permanent configuration via antifuse technology. The CQFP package provides hermetic sealing suitable for harsh environmental conditions.

Replacement Considerations

Direct replacements must match the 208-pin CQFP footprint and military temperature rating. Verify compatibility with Actel Designer or Libero IDE software tools for programming and simulation. Check if alternative speed grades or gate counts within the SX-A family meet specific timing constraints.
