• Performance  Documented family-level performance includes up to 250 MHz system performance and up to 350 MHz internal performance for timing-critical paths.
• Nonvolatile Single-Chip Solution  Built-in nonvolatile configuration removes the need for external configuration memory, simplifying board design and reducing BOM.
• Robust Power and I/O Behavior  Hot-swap compliant I/Os and power-up/power-down friendly operation (no supply sequencing required) improve system robustness during power events.
• Testability and Security  Boundary-scan testing compliant with IEEE 1149.1 (JTAG) and Actel Secure Programming Technology with FuseLock™ for design protection and anti-reverse-engineering.
• Package and Environmental  Available in a 144-pin LQFP package (supplier listing: 144-TQFP, 20×20); RoHS-compliant and offered in a military temperature grade (−55 °C to 125 °C).
• Voltage Range  Supply operation across 3 V to 5.5 V supports a broad set of system architectures and legacy interfaces.

Typical Applications

• Military and Aerospace Systems  Military-grade temperature range and package options suit control, signal conditioning and interface functions in rugged, high-reliability platforms.
• Interface Bridging and Protocol Conversion  Mixed-voltage I/O and abundant logic elements make the device well-suited for PCI and other bus interfacing, glue logic and protocol conversion tasks.
• Deterministic Embedded Control  Deterministic, user-controllable timing and strong internal performance support real-time control, sequencing and timing-critical functions.
• Secure and Testable Designs  Built-in FuseLock programming security and IEEE 1149.1 boundary-scan testability help protect IP and simplify manufacturing test flows.
