• Flip-Flop Resources — Supports up to 2,012 dedicated flip-flops for register and state-machine implementations.
• I/O Flexibility — 171 user-programmable I/O pins in the 208-pin package with configurable support for 5 V TTL/PCI, 3.3 V LVTTL, and 2.5 V LVCMOS2 signaling.
• Voltage and I/O Tolerance — Mixed-voltage operation across 2.5 V, 3.3 V and 5 V domains with 5 V input tolerance and 5 V drive strength; supply range 2.25 V to 5.25 V.
• Performance — System performance up to 250 MHz and internal performance up to 350 MHz for timing-critical logic paths.
• Nonvolatile Single-Chip — Built-in nonvolatile configuration eliminates the need for external configuration memory.
• Power-Up/Down Friendly — No sequencing required for supply voltages; devices include configurable weak-resistor pull-up or pull-down at power-up.
• I/O and System Control — Hot-swap compliant I/Os, individual output slew-rate control, and 66 MHz PCI compliance for bus-interface applications.
• Security and Testability — Actel Secure Programming Technology with FuseLock™ and IEEE 1149.1 (JTAG) boundary-scan testing support.
• Deterministic Timing & Diagnostics — Supports deterministic, user-controllable timing and in-system diagnostic/verification via Silicon Explorer II.
• Package & Grade — 208-pin BFQFP (supplier: 208-PQFP, 28×28) in commercial grade, operating 0 °C to 70 °C; RoHS compliant.

Typical Applications

• PCI and Bus Interface Logic — Use the device’s 66 MHz PCI compliance and mixed-voltage I/O to implement bus bridging, protocol translation, and glue logic on commercial systems.
• Reconfigurable Control Logic — Deploy for commercial embedded control, state machines, and timing-critical logic leveraging the device’s flip-flop resources and deterministic timing.
• Secure FPGA-Based Designs — Implement on-chip security and IP protection using the device’s FuseLock secure programming capability for protected commercial applications.

Unique Advantages

• Large, Integrated Logic Resource: 108,000 system gates and ~6,036 logic elements reduce external glue logic and simplify system architectures.
