概述

Description

LFE5U-85F-8BG381I is a mid-density FPGA from Lattice Semiconductor, part of the LFE5U family. It’s designed for low power in compact, embedded applications. The device comes in a 381-ball BGA package (BG381) and carries the industrial-temperature rating (-40 to 85°C), as indicated by the trailing I. It provides roughly 85K logic elements in the fabric, plus configurable I/O and embedded memory blocks to support a range of logic and data-path needs. This makes it suitable for embedded control, data processing, networking, imaging, and other space- and power-constrained FPGA implementations. Design flow is via Lattice design tools (Radiant/ Diamond) or compatible third-party EDA tools, using standard HDL (Verilog/VHDL) or IP cores.
