• Power-Friendly I/Os — Hot-swap compliant I/Os and power-up/power-down friendly behavior with no supply sequencing required, easing integration into multi-rail systems.
• Performance and Timing — Family-documented performance targets include 250 MHz system performance and 350 MHz internal performance; deterministic, user-controllable timing enables predictable design closure.
• System Diagnostics & Test — Boundary-scan testing compliant with IEEE 1149.1 (JTAG) and in-system diagnostic/verification capability via Silicon Explorer II.
• Security — Actel Secure Programming Technology with FuseLock™ to protect bitstream confidentiality and prevent reverse engineering.
• I/O Control — Configurable weak-resistor pull-up or pull-down at power-up and individual output slew-rate control for signal integrity tuning.
• Package & Mounting — 100-LQFP package case (surface mount); supplier device package listed as 100-TQFP (14×14).
• Electrical & Environmental — Supply voltage range 2.25 V to 5.25 V, operating temperature 0 °C to 70 °C, and RoHS compliant.
• Resource Utilization — Supports up to 100% resource utilization and 100% pin locking for deterministic implementation and pin assignment control.

Typical Applications

• Embedded Control and Glue Logic — Implement control-state machines, signal conditioning, and board-level interfacing where mid-range logic capacity and flexible I/O are required.
• Bus and Protocol Bridging — Use the device’s mixed-voltage I/O and PCI-capable features for bridging between different bus standards and voltage domains.
• Prototyping and Development — Single-chip nonvolatile configuration and family tools for in-system diagnostics make the device suitable for rapid prototyping and functional validation.
• Commercial Electronic Systems — Integrate into consumer and commercial products requiring a commercial-grade FPGA with predictable timing and configurable I/O behavior.

Unique Advantages

• Nonvolatile, single-chip solution: Eliminates external configuration components, reducing BOM complexity and board area.
• Flexible mixed-voltage I/O: Simplifies interfacing across 2.5 V, 3.3 V, and 5 V domains with 5 V input tolerance and configurable I/O standards.
• Power-up/down friendly I/Os: No supply sequencing required and hot-swap compliant I/Os reduce integration risk in multi-rail systems.
• Deterministic timing and full resource utilization: User-controllable timing and support for up to 100% utilization enable predictable synthesis and placement outcomes.
• Security and testability: FuseLock secure programming and IEEE 1149.1 boundary-scan facilitate IP protection and production test.
• Commercial operating range and compliance: Designed for 0 °C to 70 °C operation with RoHS compliance for standard commercial product deployments.
