Overview

The LFE5UM-45F-8BG381I is a member of the Lattice ECP5 FPGA family, designed for high-performance connectivity in a cost-optimized architecture. It features 44,000 logic elements and nearly 2 Mb of embedded RAM, making it suitable for applications requiring high-speed data processing and flexible I/O connectivity.

Why Choose This Part

This FPGA offers a high ratio of logic cells to power consumption, operating at a core voltage of 1.045V to 1.155V. With 203 available I/O and integrated SERDES, it provides significant connectivity options for bandwidth-intensive designs within a compact 17x17mm footprint.

Applications

Video Image Processing
Efficiently handles video scaling, color space conversion, and frame buffering in 381-ball caBGA package.
Industrial Ethernet Bridges
Implements low-latency industrial communication protocols using the integrated SERDES capabilities.
Motor Control Systems
Utilizes the 44K logic cells and high I/O count for complex multi-axis motor control and sensor fusion.
Protocol Conversion
Acts as a bridge between legacy parallel interfaces and modern high-speed serial protocols.
