The LFE3-35EA-7FTN256I is an ECP3 Field Programmable Gate Array (FPGA) IC from Lattice Semiconductor Corporation. It provides mid-range programmable logic capacity with integrated on-chip memory and a broad set of I/O for configurable digital designs.

Designed for industrial deployments, this device combines 33,000 logic elements, approximately 1.36 Mbits of embedded memory, and 133 I/O pins in a compact 256‑BGA package to support a variety of industrial and embedded system requirements.

Key Features

• Logic Resources – 33,000 logic elements for implementing combinational and sequential logic functions in configurable hardware.
• Embedded Memory – Approximately 1.36 Mbits of on-chip RAM to support buffering, FIFOs, and local data storage for custom logic blocks.
• I/O Capacity – 133 general-purpose I/O pins to interface with peripherals, sensors, and external logic devices.
• Package & Mounting – 256‑BGA package (supplier device package: 256‑FTBGA, 17×17) with surface-mount mounting for compact board integration.
• Power – Core supply voltage range of 1.14 V to 1.26 V, enabling compatibility with low-voltage system rails.
• Industrial Temperature Range – Rated for operation from -40 °C to 100 °C to meet extended temperature requirements.
• Regulatory – RoHS compliant.

Typical Applications

• Industrial Control – Implement real-time control logic and custom I/O handling in industrial systems that require extended temperature operation.
• Embedded Processing – Offload application-specific functions to hardware with 33,000 logic elements and on-chip memory for deterministic performance.
• I/O and Interface Bridging – Use 133 I/O pins to bridge and adapt signals between subsystems and external devices within compact hardware designs.

Unique Advantages

• Mid-range Logic Capacity: 33,000 logic elements provide a balance of integration and cost for many configurable logic tasks.
• On-chip Memory: Approximately 1.36 Mbits of embedded RAM reduces the need for external memory in common buffering and state-storage scenarios.
• Generous I/O Count: 133 I/O pins enable flexible interfacing options without extensive external glue logic.
• Industrial-rated Temperature: Operation from -40 °C to 100 °C supports deployments in thermally demanding environments.
• Compact, Surface-mount Package: 256‑BGA (256‑FTBGA, 17×17) allows high-density board designs while maintaining manufacturability.
• Low-voltage Core: 1.14 V to 1.26 V supply range aligns with modern low-voltage system architectures.
