• Nonvolatile Single‑Chip Architecture SX-A family architecture provides a nonvolatile, single‑chip FPGA implementation—no external configuration memory required.
• I/O Robustness and Control Hot-swap compliant I/Os, configurable weak pull-up/pull-down at power-up, and individual output slew rate control enable robust interfacing and signal integrity control.
• Package and Mounting Surface-mount 176-pin LQFP (supplier device package noted as 176-TQFP, 24×24) for compact board-level integration.
• Commercial Temperature Grade Rated for 0 °C to 70 °C operation for standard commercial applications.
• Compliance and Environmental RoHS compliant for environmentally conscious manufacturing and assembly.
• On‑chip Sequential Resources Dedicated flip‑flop resources and deterministic, user‑controllable timing enable predictable timing closure for synchronous designs.
• Test and Security Supports boundary-scan (JTAG) testing and secure programming technology for design protection and in-system diagnostics.

Typical Applications

• PCI and Bus Interface Logic Use where PCI‑compliant signaling and mid-range I/O counts are required to implement interface bridging, protocol glue logic, or peripheral controllers.
• Embedded Control Systems Suitable for embedded control tasks that need reconfigurable logic, deterministic timing, and a nonvolatile FPGA fabric without external configuration memory.
• Hot-Swap and Serviceable Systems Hot-swap compliant I/Os and configurable power-up behavior make this device appropriate for serviceable equipment and modular subsystems.
• Mixed‑Voltage Interfacing Ideal for designs that require interfacing between 5 V and 3.3 V domains with 5 V tolerant inputs and configurable I/O standards.

Unique Advantages

• Nonvolatile, single-chip solution: Eliminates the need for external configuration memory, reducing BOM count and board complexity.
• Flexible mixed-voltage I/O: Supports multiple I/O voltage levels and 5 V tolerance to simplify interfacing with legacy and modern peripherals.
