• Voltage Flexibility 3 V to 5.5 V supply range with documented 5 V input tolerance and 5 V drive strength for mixed-voltage system interfacing.
• Thermal & Grade Military grade device with operating temperature range of −55°C to +125°C and QML/MIL-STD-883 manufacturing and test flow referenced by the family documentation.
• Package & Mounting 208-BFCQFP with tie bar; supplier device package listed as 208-CQFP (75×75); surface-mount mounting type.
• Security & Diagnostics Family-level features include Actel Secure Programming Technology with FuseLock and in-system diagnostic/verification capability (as described in the datasheet).
• Standards & Testability Boundary-scan testing compliant with IEEE 1149.1 (JTAG) and family-level PCI compliance options referenced in the datasheet.
• Environmental Compliance RoHS compliant.

Typical Applications

• Military and Aerospace Systems Suited for mission-critical subsystems that require military temperature operation and QML-class processing and testing flows.
• High-Reliability Embedded Control Deterministic timing and medium-density logic resources make the device suitable for control and signal-processing tasks in secure embedded platforms.
• Mixed-Voltage Interface Use where 3.3 V and 5 V signaling coexist and I/O tolerance/drive flexibility are required for legacy or mixed-voltage peripherals.

Unique Advantages

• Military-grade qualification: Specified for −55°C to +125°C operation and produced under MIL-STD-883 product flow practices referenced by the family datasheet.
• Balanced logic density: 2,880 logic elements and ~48,000 system gates offer a compact, predictable FPGA resource set for medium-complexity designs.
• Flexible I/O and voltage support: 174 I/Os with documented mixed-voltage operation and 5 V tolerance simplify integration into systems with diverse interfaces.
• Proven timing behavior: Family-level timing figures (e.g., 5.3 ns clock-to-out and up to 215 MHz system performance at military temperatures) support deterministic design requirements.
• Security and testability: Secure programming (FuseLock) and IEEE 1149.1 boundary-scan support enhance design protection and production test coverage.
• Package consistency: 208-pin ceramic CQFP with tie bar provides a standardized, surface-mount form factor for rugged designs.
