Built for applications that require rugged temperature performance and flexible I/O and voltage support, the device combines 108,000 system gates, 6,036 logic elements, and up to 213 user-programmable I/Os in a 256-pin ceramic CQFP surface-mount package (with tie bar).

Key Features

• Core capacity — 108,000 system gates and 6,036 logic elements provide substantial logic resources for complex designs; the device includes up to 2,012 dedicated flip-flops for sequential logic.
• I/O and clock resources — 213 user-programmable I/Os and a clock architecture that includes 3 global clocks and 4 quadrant clocks to support multi-clock designs and high-pin-count interfaces.
• Performance (datasheet-specified) — Per the HiRel SX-A datasheet, the A54SX72A device is specified with a Clock-to-Out timing value of 6.7 ns (device table entry) and family-level high-speed characteristics for demanding timing requirements.
• Voltage and I/O flexibility — Supply operation from 2.25 V to 5.25 V and mixed-voltage I/O support documented for the SX-A family allow interfacing with 2.5 V, 3.3 V and 5 V domains and offer 5 V input tolerance where required.
• Package and mounting — 256-BFCQFP ceramic package with tie bar (surface-mount) suitable for board-level assemblies that require hermetic-style package options from the SX-A family.
• High-reliability and qualification — Grade: Military with datasheet references to QML-class manufacturing flow and 100% military temperature testing (–55 °C to +125 °C) for designs that demand proven environmental screening.
• Security and test features — Family-level features documented in the datasheet include secure programming technology and boundary-scan (IEEE 1149.1) support for in-system test and verification.

Typical Applications

• Military and defense systems — Rugged temperature range and military-grade qualification make the device suited for embedded processing, communications, and control functions in defense electronics.
• Avionics and avionics subsystems — Deterministic timing, high I/O count, and QML-level manufacturing flow support flight electronics and avionics control applications.
• Secure and ruggedized communications — Secure programming features and high I/O density enable protocol handling, encryption interfaces, and rugged communications line cards.
• High-reliability instrumentation — Use in instrumentation and test equipment that require verified temperature screening and long-term reliability backed by military-class testing procedures.

Unique Advantages

• High-density programmable fabric: 108,000 system gates and 6,036 logic elements allow consolidation of multiple functions into a single FPGA to reduce BOM and board complexity.
• Wide operating temperature: Guaranteed operation from –55 °C to +125 °C supports deployment in thermally challenging environments without derating.
• Flexible I/O and mixed-voltage support: Supply range of 2.25 V to 5.25 V and documented mixed-voltage operation permit direct interfacing to a variety of legacy and modern logic levels.
• QML-class manufacturing and screening: The HiRel SX-A family documentation details a MIL-STD-883 product flow and 100% military temperature testing, simplifying qualification for high-reliability programs.
• In-system test and security: Boundary-scan support and family-level secure programming features enable production testability and protection of intellectual property.
• Ceramic CQFP packaging: The 256-pin ceramic package with tie bar provides a hermetic-style option and high pin count for dense system integration.
