• Voltage and I/O Flexibility — Voltage supply range from 2.25 V to 5.25 V with family support for 2.5 V, 3.3 V and 5 V mixed-voltage operation and 5 V input tolerance and drive strength.
• Package and Mounting — 256-BFCQFP with tie bar (supplier package: 256-CQFP, 75 × 75) in a surface-mount form factor suitable for hermetic packaging options.
• Temperature and Grade — Military grade with operating temperature range of −55 °C to +125 °C and MIL-STD-883 production flow and Class B level devices.
• Security and Testability — Actel Secure Programming Technology with FuseLock™ to protect design IP, plus IEEE 1149.1 (JTAG) boundary-scan support for manufacturing and board-level test.
• System Features — Hot-swap compliant I/Os, power-up/power-down friendly operation without supply sequencing, configurable I/O pull-ups/pull-downs for controlled power-up behavior, and in-system diagnostic/verification capability.
• Compliance and Reliability — QML-certified devices, 100% military temperature tested, and designed for low power consumption consistent with HiRel family specifications.

Typical Applications

• Military & Aerospace Systems — Rugged, military-grade FPGA for mission-critical control, signal processing, and avionics subsystems operating across −55 °C to +125 °C.
• Secure and Defense Electronics — Devices requiring on-chip secure programming and IP protection benefit from FuseLock™ secure programming technology.
• High-Reliability Communications and Control — Deterministic timing, boundary-scan testability, and configurable I/Os support reliable communications, telemetry, and control applications.
• PCI-Compatible Embedded Controllers — Family-level PCI compliance and mixed-voltage I/O support enable use in embedded controllers and legacy PCI-interfacing systems.

Unique Advantages

• Military-Grade Qualification: QML class and MIL-STD-883 production flow with full temperature testing provide documented, high-reliability supply chain credentials.
• High Integration: Large logic capacity (108,000 system gates / ~6,036 logic elements) reduces bill-of-materials by consolidating multiple functions into one FPGA.
• Secure Device Programming: Built-in FuseLock™ secure programming protects designs against reverse engineering and unauthorized copying.
• Flexible I/O and Voltage Support: Wide supply voltage range (2.25–5.25 V) and mixed-voltage I/O support simplify integration with legacy and modern interfaces.
• Testability and Diagnostics: IEEE 1149.1 boundary-scan and in-system diagnostic capabilities streamline manufacturing test and field verification.
• Proven HiRel Family Features: Power-up/power-down friendly operation, hot-swap I/O compatibility, and selectable pull-up/pull-down options improve reliability in complex power environments.
