• I/O and Interface Flexibility — 171 user-programmable I/Os; family-level support for configurable I/O standards including 3.3 V/5 V PCI, LVTTL and TTL facilitates mixed-voltage system integration.
• Performance & Timing — Family datasheet cites high internal and system performance; device table lists a pin-to-pin clock-to-out of 6.7 ns for this device, enabling deterministic timing control.
• Power & Supply — Wide supply range from 2.25 V to 5.25 V and power-up/down friendly behavior that does not require supply sequencing.
• Security & Test — Actel Secure Programming Technology with FuseLock to protect design IP and built-in boundary-scan (IEEE 1149.1 JTAG) for board-level testability.
• Reliability & Qualification — Military-grade QML/Class B device flow with 100% military temperature testing (–55 °C to +125 °C) and MIL‑STD‑883 test flow for high-reliability programs.
• Package — 208‑pin ceramic BFCQFP with tie bar (supplier package: 208‑CQFP, 75×75) suitable for hermetic assembly and ruggedized systems.
• No Embedded SRAM — The device reports 0 total on-chip RAM bits; state and storage are implemented via logic elements and flip-flops.

Typical Applications

• Military & Aerospace Systems — QML/Class B qualification, full military temperature screening, and hermetic ceramic packaging make the device suitable for avionics, mission electronics, and tactical subsystems.
• Secure Embedded Control — FuseLock secure programming and deterministic timing support secure, tamper-resistant control and processing implementations.
• PCI and Mixed-Voltage Interfaces — Configurable I/O support for 3.3 V/5 V PCI and TTL/LVTTL allows implementation of interface bridging and peripheral controllers on mixed-voltage boards.
• High-Reliability Data Acquisition & Control — High logic density and extensive dedicated flip-flops enable custom signal conditioning, telemetry, and control logic for long-life systems.

Unique Advantages

• Military-Grade Assurance: QML/Class B production flow and 100% military temperature testing provide traceable qualification for defense and aerospace programs.
• High Logic Density: 108,000 system gates and 6,036 logic elements with over 2,000 dedicated flip-flops reduce the need for multiple devices and simplify complex designs.
• Flexible I/O Integration: 171 user I/Os with mixed-voltage support streamline integration with legacy 5 V systems and modern 3.3 V logic.
• Design Security & Testability: FuseLock secure programming with JTAG boundary-scan enables IP protection and robust board-level testing.
• Rugged Packaging: Ceramic 208‑pin BFCQFP with tie bar supports hermetic assembly practices required in harsh environments.
• Power-Sequence Tolerance: Power-up/down friendly operation eliminates the need for strict supply sequencing in complex power domains.
