Key Features

• Core Capacity — Approximately 24,000 system gates and 1,452 logic elements provide resources for combinatorial and sequential logic integration in a single FPGA.
• Performance — Series-level specifications include up to 250 MHz system performance and up to 350 MHz internal performance for time-critical logic paths.
• I/O and Voltage Flexibility — 147 user I/Os with configurable I/O support and mixed-voltage operation across 2.5 V, 3.3 V, and 5 V domains; device supports 3 V to 5.5 V supply range and 5 V input tolerance where applicable.
• Nonvolatile Single-Chip Solution — The SX-A family architecture provides nonvolatile configuration on-chip, eliminating the need for external configuration memory.
• System and Test Support — Boundary-scan testing compliant with IEEE 1149.1 (JTAG) and in-system diagnostic and verification capabilities as provided by SX family tooling.
• Power and Hot-Swap Features — Power-up/power-down friendly operation with no sequencing required for supply voltages and hot-swap compliant I/Os for robust board-level behavior.
• Package and Mounting — Available in a 176-pin thin quad flat pack (176-LQFP / 176-TQFP 24×24) with surface-mount mounting for standard PCB assembly.
• Environmental and Temperature — Industrial-grade device with operating temperature range from −40°C to +85°C and RoHS-compliant materials.
• Security — Series feature set includes secure programming technology (FuseLock™) to protect designs from reverse engineering and unauthorized readback.

Typical Applications

• Industrial Control — Implement custom control logic, sensor interfacing, and real-time decision-making functions in industrial automation systems operating across industrial temperature ranges.
• Embedded System Glue Logic — Replace discrete glue logic with a single FPGA to consolidate interfaces, bus bridging, and custom peripherals while reducing BOM complexity.
• Communications and I/O Translation — Use configurable I/O and mixed-voltage support to implement protocol adapters, level translation, and timing-critical I/O handling.
• Instrumentation and Test Equipment — Leverage deterministic timing and in-system diagnostic capabilities for measurement, data acquisition, and verification subsystems.

Unique Advantages

• Highly integrated logic resources: 1,452 logic elements and 24,000 system gates enable consolidation of multiple discrete functions into one device, reducing board complexity.
• Nonvolatile configuration: Single-chip nonvolatile architecture eliminates external configuration memory, simplifying design and improving boot reliability.
• Flexible I/O and mixed-voltage support: Configurable I/O and 3 V to 5.5 V supply range support diverse interface requirements without additional level-shifting components.
• Industrial temperature rating: −40°C to +85°C operation suits deployments in industrial environments that require extended temperature tolerance.
• Built-in test and security: IEEE 1149.1 boundary-scan and FuseLock™ programming increase testability and protect intellectual property on the device.
• RoHS-compliant and surface-mount packaging: 176-LQFP package and RoHS compliance align with modern manufacturing and environmental requirements.
