Overview

The LFE5U-85F-6BG381C is a high-density ECP5 series FPGA from Lattice Semiconductor, featuring 84,000 logic cells and 3.8 Mbits of embedded RAM. Operating on a 1.1V core voltage, it is designed for low-power applications requiring high-performance digital signal processing and flexible I/O connectivity in a compact 381-ball CABGA package.

Why Choose This Part

This FPGA offers an excellent balance of logic density and power efficiency with a low 1.1V core supply and 0.5uA standby current. It provides robust system reliability through Single Event Upset (SEU) mitigation support and Dual-boot image capability for fail-safe field updates.

Applications

Video Processing
Utilizing 7:1 LVDS and dedicated gearing logic for high-resolution display interfacing and image processing.
Industrial Networking
Implementing XGMII and Ethernet protocols for low-latency industrial communication bridging.
Memory Interfacing
Supporting DDR3 and LPDDR3 at rates up to 800 Mb/s using dedicated read/write leveling and DQS logic.
Motor Control
Leveraging internal DSP slices and PLLs for high-speed PWM generation and sensor fusion.
