Key Features

• Core Capacity — 48,000 system gates and approximately 2,880 logic elements provide programmable logic density suitable for complex control and signal routing tasks.
• User I/O — 69 I/O pins in the 84-pin CQFP package support mixed-voltage interfacing and flexible system connectivity.
• Military Temperature Range — 100% tested for operation from −55°C to +125°C, addressing high-reliability and ruggedized system requirements.
• Wide Supply Range — Operates across 2.25 V to 5.25 V, enabling integration with diverse legacy and modern voltage domains.
• Package and Mounting — 84-CQFP (42 × 42 mm) ceramic quad flat pack with exposed pad and tie bar; surface-mount mounting for PCB-level robustness.
• HiRel SX-A Family Features — Family-level capabilities include deterministic, user-controllable timing, boundary-scan (JTAG) support, and secure programming technology (FuseLock™) that helps protect designs from reverse engineering.
• High-Performance Timing (Family) — SX-A family performance metrics include up to 215 MHz system performance and 5.3 ns clock‑to‑out at military temperature grades.
• Qualification and Compliance — Classified as Military grade and supplied in a QML/Class B product flow with MIL-STD-883 screening and burn-in procedures (per family datasheet).
• Environmentally Compliant — RoHS compliant for regulated-material conformity.

Typical Applications

• Military & Defense Systems — Rugged, temperature‑rated FPGA logic for mission-critical control, signal processing, and interface conversion in tactical electronics.
• Avionics and Aerospace — Deterministic timing and high-reliability packaging suitable for avionics subsystems requiring ceramic packages and MIL temperature grades.
• Secure Embedded Systems — FuseLock™ secure programming and boundary-scan support help protect intellectual property and enable in-system testability.
• High-Reliability Instrumentation — Compact FPGA resources and wide supply tolerance make the device suitable for test, measurement, and rugged instrumentation designs.

Unique Advantages
