• Performance (series-level) — Series datasheet specifies up to 250 MHz system performance and up to 350 MHz internal performance.
• Voltage & Mixed-Voltage Support — Device supply range 2.25 V to 5.25 V; series-level support for 2.5 V, 3.3 V and 5 V mixed-voltage operation with 5 V input tolerance and 5 V drive strength.
• Configuration & Security — Nonvolatile single-chip configuration and Actel Secure Programming Technology (FuseLock) to protect design intellectual property (as noted in the series datasheet).
• System Compatibility — Series-level features include hot-swap compliant I/Os, 66 MHz PCI compliance, boundary-scan (IEEE 1149.1 JTAG) support and deterministic, user-controllable timing.
• On-chip Memory — Total on-chip RAM: 0 bits (no embedded RAM).
• Package & Mounting — 208-pin BFQFP, surface-mount package (supplier device package listed as 208-PQFP 28×28).
• Environmental & Grade — Commercial temperature grade with operating range 0 °C to 70 °C and RoHS compliance.

Typical Applications

• Interface Bridging and Level Translation — Mixed-voltage I/O and 5 V tolerance simplify direct interfacing between legacy 5 V logic and 3.3 V/2.5 V systems without extensive external level-shifting.
• PCI Subsystems and Legacy Bus Logic — Series-level 66 MHz PCI compliance and programmable I/O make the device suitable for implementing PCI-compatible glue logic and bus adapters.
• Embedded Control and Glue Logic — The nonvolatile single-chip configuration and deterministic timing support control, sequencing, and peripheral aggregation tasks in commercial electronics.
• Secure Programmable Logic — On-chip secure programming technology (FuseLock) reduces the risk of reverse engineering for sensitive designs that require IP protection.

Unique Advantages

• Nonvolatile single-chip configuration: Eliminates the need for external configuration memory and simplifies system power-up behavior.
• Mixed-voltage I/O capability: Supports multiple interface voltages and 5 V tolerance, reducing BOM by minimizing external level shifters.
• Integrated security features: Built-in FuseLock programming technology provides a hardware mechanism to protect design IP.
• Deterministic, user-controllable timing: Series-level deterministic timing facilitates repeatable timing closure and system verification.
• Surface-mount 208-pin BFQFP: High pin-count packaging in a compact footprint suitable for dense PCB layouts.
• RoHS compliant: Conforms to lead-free manufacturing requirements for commercial electronic assemblies.
