LFE5UM in Lattice ECP5 Family
The LFE5UM sub-family, part of the Lattice Semiconductor ECP5 series, is a range of high-performance FPGAs designed to bridge the gap between low-cost programmable logic and high-end SoC devices. These components offer high-density lookup tables (LUTs), dedicated digital signal processing blocks, and integrated SERDES channels. They are specifically optimized for cost-sensitive applications requiring high bandwidth, low power consumption, and a small physical footprint, making them ideal for high-speed communication interfaces and data processing tasks in embedded systems.

Comparing specs that differ across variants.
| Part Number | I/O Pins | Total RAM Bits | Number of LABs/CLBs | Number of Logic Elements/Cells | Stock |
|---|---|---|---|---|---|
| LFE5UM-45F-VERSA-EVN (Lattice Semiconductor Corporation) | — | — | — | — | 15 |
| LFE5UM-45F-6BG381C (Lattice) | 203 | 1990656 | 11000 | 44000 | 89 |
| LFE5UM-85F-8BG381C (Lattice) | 205 | 3833856 | 21000 | 84000 | 64 |
Variants within the LFE5UM sub-family are primarily distinguished by logic density, ranging from 24K to 85K LUTs, and SERDES channel availability. Speed grades (marked as -6, -7, or -8) dictate maximum operating frequencies and timing margins. Packaging options include fine-pitch BGA (caBGA) and chip-scale packages, with temperature ratings available for both commercial (0C to 85C) and industrial (-40C to 100C) environments to meet specific ruggedization requirements.
