• Voltage and Power — Operates across a broad supply range (2.25 V to 5.25 V) and supports mixed-voltage operation (2.5 V, 3.3 V, and 5 V) with 5 V input tolerance and 5 V drive strength.
• Performance (SX-A family) — Family-level performance up to 250 MHz system performance and up to 350 MHz internal performance for timing-critical functions.
• Package and Mounting — 208-pin BFQFP / PQFP (28 × 28 mm) package, surface-mount mounting type suitable for board-level assembly in commercial products.
• System and Configuration — Nonvolatile, single-chip solution with Power-Up/Down friendly operation (no sequencing required) and hot-swap compliant I/Os for robust system behavior.
• Design-for-Test and Security — Boundary-scan (IEEE 1149.1 JTAG) support for manufacturing test and Actel Secure Programming Technology with FuseLock™ for protection against reverse engineering.
• Programmability and Diagnostics — Deterministic, user-controllable timing, configurable weak-resistor pull-up/pull-down at power-up, individual output slew-rate control, and in-system diagnostic and verification capability with Silicon Explorer II.
• Compliance and Temperature — Commercial temperature grade (0 °C to 70 °C) and RoHS-compliant material status for regulatory and environmental compatibility.

Typical Applications

• PCI and Bus Interfaces — Implement PCI-compliant peripherals and bus-bridging logic leveraging the device's 66 MHz PCI support and configurable 3.3 V / 5 V I/O options.
• Embedded Glue Logic — Replace discrete glue logic and combine control functions in a single nonvolatile FPGA to simplify board-level design and reduce BOM count.
• In-System Programmable Designs — Use the nonvolatile single-chip architecture and in-system diagnostics for designs requiring field updates and on-board verification.
• Secure and Protected IP — Apply FuseLock™ secure programming to protect design IP against reverse engineering in commercial products.

Unique Advantages

• Nonvolatile Single-Chip Solution: Eliminates external configuration memory and simplifies system boot and deployment.
• Flexible Mixed-Voltage I/O: Configurable I/O standards and 5 V tolerance enable direct interfacing with a wide range of legacy and modern logic levels.
• Robust System Behavior: Power-Up/Down friendly operation and hot-swap compliant I/Os reduce system-level sequencing constraints and support resilient designs.
• Manufacturing and Field Testability: Boundary-scan (JTAG) support and Silicon Explorer II diagnostics streamline production test and in-system verification.
• IP Protection: Actel FuseLock™ secure programming provides a hardware-level method to protect proprietary designs.
• Commercial-Grade Packaging: 208-pin PQFP surface-mount package and RoHS compliance fit standard commercial product assembly and environmental requirements.
