Key Features

• Core Capacity — 48,000 system gates and approximately 2,880 logic elements provide a mid-range programmable fabric for glue logic, protocol bridging and control functions.
• Programmable Flip-Flops — Family datasheet indicates up to 2,012 dedicated flip-flops are available for state, pipelining and timing control.
• I/O and Voltage Flexibility — 113 user-programmable I/Os on the 144-pin package with configurable I/O support across common signaling levels and mixed-voltage operation (2.5 V, 3.3 V and 5 V) and 5 V input tolerance.
• Performance — SX-A family performance indicators include system performance up to 250 MHz and internal performance up to 350 MHz for timing-critical designs.
• Nonvolatile Single-Chip Solution — Built-in nonvolatile configuration removes the need for external configuration memory and simplifies power-up behavior.
• System Reliability and Test — Boundary-scan testing compliant with IEEE 1149.1 (JTAG) and unique in-system diagnostic/verification capability with Silicon Explorer II (family feature) aid board-level test and verification.
• Power and I/O Controls — Hot-swap compliant I/Os, configurable weak pull-up/pull-down at power-up and individual output slew rate control support robust system integration.
• Package and Mounting — Available in a 144-LQFP / 144-TQFP (20×20) leaded surface-mount package suitable for standard PCB assembly processes.
• Commercial Temperature Grade — Operates from 0 °C to 70 °C and supports a wide supply range from 2.25 V to 5.25 V.
• RoHS Compliance — Device is RoHS compliant.

Typical Applications

• Commercial Embedded Control — Implement glue logic, control state machines and peripheral interfacing where a mid-range programmable fabric is required.
• Interface Bridging and Protocol Conversion — Use the device’s flexible I/O voltage support and deterministic timing for bridging between 3.3 V and 5 V buses or legacy interfaces.
• PCI-Compatible Systems — SX-A family support for 66 MHz PCI signaling and configurable I/O levels make it suitable for PCI-compliant designs that need onboard programmable logic.
• Board-Level Test and In-System Verification — Leverage boundary-scan (IEEE 1149.1) and in-system diagnostic capability to streamline manufacturing test and field diagnostics.

Unique Advantages

• Nonvolatile, single-chip configuration: Eliminates the need for external configuration memory, simplifying BOM and power-up sequencing.
• Flexible mixed-voltage I/O: Support for 2.5 V, 3.3 V and 5 V operation with 5 V tolerance enables direct interfacing with a variety of legacy and modern peripherals.
• Deterministic timing and high internal performance: Family performance metrics (up to 250 MHz system, up to 350 MHz internal) support timing-sensitive logic and high-speed internal paths.
• Built-in testability: IEEE 1149.1 boundary-scan and in-system diagnostics improve board-level debug and manufacturing yield.
• Compact, surface-mount package: 144-LQFP / 144-TQFP packaging offers a balance of pin count and PCB footprint for space-constrained commercial designs.
