LFE5U-25F-6BG381C
Overview
The LFE5U-25F-6BG381C is a member of the ECP5 FPGA family from Lattice Semiconductor, designed to provide high-performance programmable logic in a small form factor and low power envelope. This device features 24,000 logic elements and over 1,000 kb of embedded block RAM, making it suitable for hardware acceleration and interface bridging. It is optimized for cost-sensitive applications that require flexibility beyond what a standard microcontroller can offer.
Why Choose This Part
The ECP5 architecture offers a high ratio of DSP slices and RAM to logic cells, enabling complex signal processing in a compact 17x17mm package. It supports a wide variety of I/O standards, including MIPI D-PHY and LVDS, while maintaining a low core voltage of 1.1V for reduced thermal overhead.
Applications
Key Specifications
Getting Started
Development typically utilizes the Lattice Diamond design software for synthesis and routing. For an open-source workflow, this device is supported by Project Trellis, allowing engineers to use the Yosys and nextpnr toolchain. Practical evaluation can be performed using the ECP5-5G Development Kit or third-party boards like the OrangeCrab or ECP5-EVN.
