A54SX32-1CQ208

Overview

The A54SX32-1CQ208 is a HiRel SX-A Field Programmable Gate Array featuring 48,000 system gates and 2,880 logic modules. It operates at a maximum internal clock frequency of 240 MHz with a pin-to-pin clock-to-out delay of 5.3 ns in military temperature ranges. The device utilizes a 0.25 µm CMOS process technology and supports mixed-voltage operation at 2.5 V, 3.3 V, and 5 V with 5 V input tolerance. It is housed in a hermetic Ceramic Quad Flat Pack (CQFP) package with 208 terminals.

Feature Summary

• Military-grade reliability with QML certification and MIL-STD-883 Class B compliance
• Nonvolatile antifuse architecture providing deterministic timing and design security
• Hot-swap compliant I/Os supporting cold-sparing applications without voltage sequencing
• Integrated Boundary Scan Testing (BST) compliant with IEEE 1149.1 (JTAG)

Applications

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

Procurement Notes

Verify the specific ordering suffix to confirm the package type and application grade. Ensure the component meets the required environmental specifications for the target deployment. Confirm that the manufacturer documentation aligns with current quality management standards. Check for any export control classifications applicable to high-reliability microelectronics.

Selection Notes

Select this model when a nonvolatile FPGA solution with guaranteed performance across extreme temperatures is required. The CQFP package is suitable for applications necessitating hermetic sealing. Consider the 240 MHz internal speed and 5.3 ns external delay for timing-critical designs. Evaluate the 48,000 gate capacity against the complexity of the intended logic implementation.

Part Context

This component belongs to the Actel HiRel SX-A family of FPGAs, designed for high-reliability environments. The SX-A series is characterized by its metal-to-metal antifuse technology, which offers low power consumption and immunity to single-event upsets compared to SRAM-based devices. This specific part represents a mid-range density option within the family.

Replacement Considerations

Direct replacements must match the 208-pin CQFP hermetic package and military temperature range. Verify compatibility with existing programming tools and fuse files. Cross-reference with other HiRel SX-A variants if gate count or speed requirements differ.
