A54SX72A-1CQ256M

The A54SX72A-1CQ256M is a military-grade SX‑A family FPGA in a 256-pin ceramic CQFP package with tie bar. Designed for high-reliability embedded systems, it provides a dense logic fabric with deterministic timing and a wide operating range for use in harsh environments.

This device targets aerospace, defense and other mission-critical applications that require QML-level screening, extended temperature operation and secure programmable logic with configurable I/O support across multiple voltage domains.

Key Features

• Logic Capacity — 108,000 system gates and 6,036 logic elements provide substantial programmable logic resources for complex functions and system consolidation.
• User I/O — 213 user-programmable I/O pins with configurable support for 3.3 V/5 V PCI, LVTTL and TTL signaling to interface with a broad range of peripherals.
• Timing and Performance — Family-level performance includes up to 215 MHz system performance (military temperature) and 240 MHz internal performance; the A54SX72A device has a documented clock-to-out of 6.7 ns.
• Power and I/O Behavior — Hot-swap compliant I/Os and power-up/power-down friendly operation with no required sequencing for supply voltages.
• Security and Testability — Actel Secure Programming Technology with FuseLock to protect design IP; boundary-scan testing compliant with IEEE 1149.1 (JTAG) for manufacturing diagnostics.
• Reliability and Screening — Military grade with QML certification and 100% military temperature testing (–55°C to +125°C) per device flow; meets MIL-STD-883 product flow screening.
• Voltage and Mounting — Broad supply range from 2.25 V to 5.25 V; surface-mount ceramic 256-BFCQFP package (supplier package: 256-CQFP, 75 × 75).
• Embedded Memory — No embedded RAM bits (Total RAM Bits: 0), enabling deterministic resource planning for external memory needs.
• RoHS Compliance — Device is RoHS compliant.

Typical Applications

• Military and Aerospace Systems — Flight electronics, avionics controllers and mission systems that require QML screening and operation across –55°C to +125°C.
• Secure Embedded Systems — Applications needing hardware IP protection and anti-reverse-engineering measures using FuseLock secure programming.
• High-Reliability Control — Deterministic timing and hot-swap I/O support for redundant control, telemetry and data-acquisition subsystems.
• Boundary-Scan Test Environments — Designs that leverage IEEE 1149.1 JTAG for in-circuit testability and board-level diagnostics.

Unique Advantages

• QML‑level Screening: Designed and tested to military screening flows (MIL-STD-883), supporting deployment in mission-critical environments.
• Secure Programming: FuseLock technology protects design IP and helps prevent reverse engineering.
• Wide Voltage Support: 2.25 V to 5.25 V supply range and 5 V input tolerance on I/Os simplify mixed-voltage system integration.
• High I/O Count: 213 user I/Os enable extensive peripheral interfacing without external glue logic.
• Deterministic, Testable Design: Fixed timing characteristics and IEEE 1149.1 boundary-scan support improve verification and manufacturing yield.
• Military Temperature Tested: 100% tested across –55°C to +125°C for predictable behavior in extreme environments.
