• Performance  Documented system performance up to 250 MHz and internal performance up to 350 MHz for latency-sensitive paths.
• Power and Supply  Wide operating supply range from 2.25 V to 5.25 V and power-up/down friendly behavior that requires no sequencing of supply voltages.
• Package and Mounting  256-FPBGA (17×17) fine-pitch BGA, surface-mount package for compact board-level integration.
• Environmental and Grade  Military grade device with operating temperature range of −55 °C to +125 °C and RoHS-compliant packaging.
• Security and Test  Nonvolatile single‑chip architecture with Actel Secure Programming Technology (FuseLock) and IEEE 1149.1 boundary-scan testing support for IP protection and board-level testability.
• Diagnostics and Verification  In-system diagnostic and verification capability via Silicon Explorer II for on-board validation and troubleshooting.

Typical Applications

• Military and Aerospace Systems  Military-grade temperature range and rugged supply tolerance make the device suitable for embedded control, signal processing interface logic, and mission-critical subsystems.
• PCI-Based Interfaces  Configurable I/O supporting 3.3 V / 5 V PCI levels is useful for implementing PCI-compliant interface logic and bridge functions.
• Secure and Protected Designs  FuseLock secure programming supports applications that require protection from reverse engineering and IP theft.
• In-System Diagnostics and Prototyping  Built-in in-system verification features enable board bring-up, diagnostics, and iterative hardware validation.

Unique Advantages

• High-density, nonvolatile logic: 108,000 system gates and 6,036 logic elements deliver substantial programmable capacity without external configuration memory.
• Wide I/O and voltage support: 203 user I/Os with mixed-voltage operation and 5 V tolerance/drive simplify interfacing to diverse legacy and modern peripherals.
• Rugged operating envelope: Military grade and −55 °C to +125 °C operating range support deployment in harsh and temperature-extreme environments.
• Deterministic performance: Documented system and internal performance figures enable predictable timing for latency-sensitive designs.
• Integrated security and test: FuseLock programming plus boundary-scan support reduce risk from IP compromise and improve manufacturability and test coverage.
• Single-chip solution: Nonvolatile FPGA architecture eliminates the need for external configuration devices, simplifying BOM and system-level design.
