A54SX72A-1CQ256B

The A54SX72A-1CQ256B is a military-grade FPGA in Microchip Technology’s HiRel SX‑A family. It delivers high logic density with 108,000 system gates and approximately 6,036 logic elements, packaged in a 256‑pin BFCQFP ceramic package with tie bar for surface-mount assembly.

Designed for high-reliability and mission-critical applications, this device supports wide supply voltage operation (2.25 V to 5.25 V) and full military temperature operation (‑55 °C to +125 °C), making it suitable for hardened embedded control, communications, and defense electronics requiring deterministic programmable logic.

Key Features

• Logic Capacity — 108,000 system gates and 6,036 logic elements provide substantial programmable logic resources for complex glue logic, protocol handling, and control functions.
• I/O — 203 user I/O pins (surface-mount) support flexible interfacing to external devices and boards.
• Voltage Flexibility — 2.25 V to 5.25 V supply range enables mixed-voltage system designs and tolerance to a broad set of legacy and modern signaling levels.
• Military Temperature Grade — Specified operating range from ‑55 °C to +125 °C for deployment in extreme environments.
• Package — 256‑BFCQFP ceramic quad flat package with tie bar; supplier package reference: 256‑CQFP (75×75).
• Performance (family-level) — The HiRel SX‑A family datasheet specifies leading-edge performance characteristics, including high internal and system clock performance for time-critical designs.
• System and Test Support — Family documentation lists features such as boundary-scan (IEEE 1149.1/JTAG) and in-system diagnostic/verification capability.
• Compliance — RoHS compliant and offered in MIL grade per product specification.

Typical Applications

• Military & Aerospace Systems — Deterministic programmable logic for communications, signal processing, and mission-critical control where military temperature and ceramic packaging are required.
• High-Reliability Embedded Control — Reconfigurable control logic for avionics, weapon systems, and hardened embedded controllers that demand wide temperature and voltage tolerance.
• Secure and Protected Designs — Use in systems that require secure programmable logic; the SX‑A family documentation includes secure programming technology references.
• Legacy Interface Integration — Bridge and timing logic for mixed-voltage and legacy interfaces where 2.25–5.25 V operation and abundant I/O simplify board-level design.

Unique Advantages

• High Logic Density: 108,000 system gates and ~6,036 logic elements allow consolidation of multiple discrete functions into a single FPGA, reducing BOM and board area.
• Wide Voltage Range: 2.25 V to 5.25 V operation supports mixed-voltage systems and eases integration with both modern and legacy devices.
• Military Temperature Rating: Rated for ‑55 °C to +125 °C operation to meet the demands of harsh environments and long-term fielded systems.
• Ceramic, Tie-Bar Package: 256‑pin BFCQFP with tie bar provides a robust, surface-mount ceramic option suitable for high-reliability assemblies.
• RoHS Compliant: Meets applicable RoHS environmental requirements while retaining military-grade specifications.
• Family-Level Diagnostics & Testability: SX‑A family features such as boundary-scan and in-system diagnostics support manufacturing test and field verification.
