• User I/O — 147 user-programmable I/Os to support a variety of peripheral interfaces and board-level connections.
• Nonvolatile Single-Chip Architecture — SX-family nonvolatile FPGA architecture eliminates separate configuration memory for simplified system design and predictable startup behavior.
• Performance — SX-family documented system and internal performance points (e.g., 250 MHz system, 350 MHz internal) for timing headroom in control and data-path logic implementations.
• Mixed-Voltage I/O and Tolerance — Configurable I/O supports multiple voltage standards and mixed-voltage operation with 5 V input tolerance and 5 V drive strength as specified for the SX family.
• Power-Up/Down Friendly I/Os — I/Os are designed to tolerate power sequencing without requiring strict supply ordering, suitable for complex multi-rail systems.
• Industrial Grade and Temperature Range — Industrial-grade device with operating temperature from -40 °C to +85 °C for deployed embedded and industrial applications.
• Supply Voltage Range — Operates from 3 V to 5.5 V, enabling compatibility with a range of legacy and modern logic families.
• Security and Test — Family-level features include JTAG boundary-scan for board-level test and Actel FuseLock™ style secure programming technology to protect designs against reverse engineering.
• Package — 176-pin LQFP package (supplier device package listed as 176-TQFP (24x24)), suitable for surface-mount assembly.
• Standards and Interoperability — SX-family devices document PCI support and hot-swap compliant I/Os for use in interface and hot-pluggable systems.
• RoHS Compliant — Device meets RoHS compliance requirements.

Typical Applications

• Industrial Control — Deterministic timing, industrial temperature rating and mixed-voltage I/O make the device well suited for motor control, PLC logic and factory automation interfaces.
• Embedded Interface Bridging — Use the 147 I/Os and mid-range logic capacity for protocol conversion, bus bridging, and custom peripheral expansion on embedded boards.
• PCI and Peripheral Subsystems — Family-level PCI compliance and hot-swap capable I/Os support add-on card logic, I/O front-ends and slot-based peripheral designs.
• Secure, Field-Reprogrammable Logic — Nonvolatile single-chip architecture and built-in secure programming support in-system updates and protected IP deployment.

Unique Advantages

• Integrated Nonvolatile Solution: Eliminates external configuration memory and simplifies power-up behavior for faster, more predictable system bring-up.
• Flexible Voltage and I/O Support: Mixed-voltage operation and 5 V input tolerance enable straightforward interfacing to legacy and modern logic levels without extensive level shifting.
