LFE5UM-25F-8BG381I

The LFE5UM-25F-8BG381I is an industrial-grade FPGA from Lattice Semiconductor's ECP5 family. It provides a mid-density FPGA fabric with 24,000 logic elements and approximately 1.03 Mbits of embedded RAM, packaged in a high-density 381‑FBGA (supplier package: 381‑CABGA, 17×17) surface-mount package.

With 197 user I/Os, a narrow core supply range (1.045 V to 1.155 V) and an extended operating temperature range (−40 °C to 100 °C), this device targets industrial and communications-focused designs that require a balance of integration, I/O density and on-chip memory.

Key Features

• Core Logic  24,000 logic elements provide mid-range programmable logic capacity suitable for complex glue logic, protocol bridging and moderate-compute tasks.
• Embedded Memory  Approximately 1.03 Mbits of on-chip RAM for data buffering, packet staging, and local storage inside the FPGA fabric.
• I/O and Packaging  197 user I/Os in a 381‑FBGA package (supplier: 381‑CABGA, 17×17) enables high-density interfacing in a compact surface-mount form factor.
• Industrial Temperature Range  Rated for −40 °C to 100 °C operation to meet industrial environmental requirements.
• Low-Voltage Core Supply  Core supply specification of 1.045 V to 1.155 V supports low-voltage system designs and predictable power budgeting.
• Family-Level Architecture  As part of the ECP5 family (per the ECP5 family datasheet), the device benefits from documented architecture features such as programmable I/O cells, clocking structures including PLLs, DDR memory support, SERDES/PCS blocks and on-chip configuration options.
• Surface Mount  Surface-mount package suitable for automated PCB assembly processes.
• RoHS Compliant  Manufactured to meet RoHS environmental compliance requirements.

Typical Applications

• Industrial Automation  Mid-density programmable logic for control, sensor interfacing and protocol conversion in industrial equipment operating across a wide temperature range.
• Communications Equipment  I/O density and ECP5 family SERDES/PCS and DDR support (per family datasheet) make the device suitable for networking and connectivity modules.
• Embedded Systems & Prototyping  Provides on-chip memory and logic capacity for embedded system prototypes, custom accelerators and interface bridging.
• High‑Density I/O Systems  Large number of user I/Os supports board-level aggregation, multi-protocol front-ends and complex peripheral interfaces.

Unique Advantages

• Balanced Logic and Memory:  24,000 logic elements paired with approximately 1.03 Mbits of embedded RAM delivers a balanced platform for both control logic and data buffering.
• High I/O Count in Compact Package:  197 I/Os in a 381‑FBGA (381‑CABGA 17×17) package reduces board-level routing complexity while keeping a small PCB footprint.
• Engineered for Industrial Use:  Rated for −40 °C to 100 °C operation, supporting deployments in demanding environmental conditions.
• Low-Voltage Core Operation:  Narrow core voltage range (1.045 V–1.155 V) simplifies power supply design and aids predictable power budgeting.
• Family-Level Capabilities:  Leverages ECP5 family architecture elements—programmable I/O cells, clocking/PLL structures, DDR support and SERDES/PCS blocks—documented in the ECP5 family datasheet.
• Regulatory and Assembly Ready:  RoHS-compliant surface-mount package suitable for modern automated assembly processes.
