This device is supplied in a compact 256-BGA package and operates over an industrial temperature range, providing a balance of integration and robustness for designs that require significant logic, memory and I/O density within a surface-mount form factor.

Key Features

• Logic Capacity — 19,000 logic elements to implement combinational and sequential logic for medium-complexity FPGA designs.
• Embedded Memory — Approximately 1.246 Mbits of on-chip RAM to store buffers, state machines and data structures without external memory.
• I/O Density — 140 user I/O pins suitable for multi-peripheral interfacing and parallel signal routing.
• Power — Core supply voltage range from 1.14 V to 1.26 V to match system power architectures requiring low-voltage FPGA cores.
• Package & Mounting — 256-BGA (supplier device package: 256-FPBGA, 17×17) in a surface-mount configuration for compact PCB implementation.
• Industrial Temperature Range — Rated for operation from −40 °C to 100 °C for reliable operation in industrial environments.
• RoHS Compliance — Environmentally compliant for regulated manufacturing processes.

Typical Applications

• Industrial Control — Implement control logic, I/O aggregation and deterministic processing for factory automation and machine control systems.
• Communications & Networking — Use the device’s I/O density and embedded memory for protocol bridging, packet buffering and interface adaptation.
• Test & Measurement — Deploy in instrumentation where on-chip memory and configurable logic are used for real-time signal processing and data capture.
