LFE2-20E-6FN256I

The LFE2-20E-6FN256I is an industrial‑grade Field Programmable Gate Array (FPGA) in the Lattice ECP2 family designed for integration into space‑constrained boards and systems. Built around a mid‑density logic fabric, this device delivers 21,000 logic elements, a high I/O count and on‑chip RAM to address control, interface and signal‑processing tasks in industrial and embedded applications.

With a low core voltage range and extended operating temperature, the LFE2-20E-6FN256I is aimed at designs that require reliable operation across harsh environments while keeping board area and BOM complexity down.

Key Features

• Logic Capacity  Provides 21,000 logic elements for combinational and sequential logic implementation and mid‑range integration of control and glue logic on a single device.
• Embedded Memory  Includes 282,624 bits of on‑chip RAM — approximately 0.283 Mbits — suitable for buffering, small FIFOs, and local state storage.
• High I/O Count  Offers 193 user I/Os to support wide parallel interfaces, peripheral bridging, and dense board‑level connectivity.
• Industrial Temperature Range  Rated for operation from −40 °C to 100 °C for deployment in industrial and ruggedized environments.
• Low‑Voltage Core  Operates from a 1.14 V to 1.26 V supply, compatible with modern low‑voltage power rails and system power budgeting.
• Compact Package  Supplied in a 256‑ball fpBGA package (256‑FPBGA, 17×17 mm) optimized for surface‑mount assembly and compact board layouts.
• Mounting & Compliance  Surface‑mount package with RoHS compliance to meet common environmental and manufacturability requirements.
• Family‑Level Capabilities  The ECP2 family includes enhanced DSP resources, flexible embedded memory structures and programmable I/O standards support, enabling efficient implementation of signal processing and mixed‑interface designs.

Typical Applications

• Industrial Control & Automation  Implements motor control logic, deterministic I/O handling and protocol bridging in industrial equipment thanks to its industrial temperature rating and rich I/O count.
• Embedded Interfaces & Bridge Logic  Consolidates parallel and serial peripherals, acting as a protocol translator or glue logic element between controllers and sensors or actuators.
• Data Acquisition & Signal Processing  Supports local data buffering and processing tasks where mid‑range logic and on‑chip RAM are required for filtering, decimation, or aggregation.
• Compact, High‑Density Boards  The 256‑ball fpBGA package and surface‑mount profile make this device suitable for space‑constrained embedded platforms and mezzanine cards.

Unique Advantages

• Balanced Integration:  Combines 21,000 logic elements with on‑chip RAM and a high I/O count to reduce external glue logic and simplify bill of materials.
• Industrial Reliability:  Rated −40 °C to 100 °C for sustained operation in industrial temperature environments, helping designs meet field‑use requirements.
• Low‑Voltage Operation:  1.14 V to 1.26 V core supply reduces power delivery complexity for modern low‑voltage systems.
• Compact, Assembly‑Friendly Package:  256‑FPBGA (17×17 mm) balances I/O density with a small board footprint for compact systems.
• RoHS Compliant:  Meets common environmental requirements to support regulated manufacturing and deployment.
• Family Ecosystem:  Leverages the ECP2 family’s DSP and memory architecture for designs that may scale across other family members.
