LFE5UM-85F-8BG756C

Product Overview

The Lattice Semiconductor Corporation LFE5UM-85F-8BG756C is an ECP5 field programmable gate array (FPGA) for embedded logic applications. It provides 84,000 logic elements or cells, 21,000 LABs/CLBs, and 3,833,856 total RAM bits, along with 365 I/O pins for external device connection. The device operates from a 1.045 V to 1.155 V supply and is specified for a junction temperature range of 0°C to 85°C. It uses a 756-FBGA surface-mount package, with a 756-CABGA (27 x 27) package footprint.

Design & Procurement Notes

For board design, consider the 1.045 V to 1.155 V supply range when planning regulated power delivery. The 756-CABGA (27 x 27) surface-mount package influences PCB land pattern, routing density, soldering process, and inspection or rework access. The 365 I/O count should be mapped early against connector and routing requirements. The 84,000 logic elements, 21,000 LABs/CLBs, and 3,833,856 total RAM bits define the available logic and memory budget, while the 0°C to 85°C (TJ) range requires junction temperature monitoring and adequate thermal design.
