LFE5U-45F-6BG256C

LFE5U-45F-6BG256C is a Lattice ECP5 FPGA with 44K LUTs, 197 user I/O and 1.9 Mbit embedded RAM in a 14x14 mm 256-ball caBGA — for connectivity-heavy designs that need real FPGA fabric without the power budget of high-end families: industrial video cameras, small-cell basebands and embedded vision preprocessors. The 1.1V core with 40-nm low-power process keeps static draw low, while 72 DSP blocks and 108 sysMEM blocks handle filtering and buffering on-chip. Selection advice: this is the LFE5U (logic-only) variant — for SERDES-based protocols specify the LFE5UM instead, since this code has no transceivers; the -6 speed grade is the fastest commercial option. ECP5 sits between MachXO3 control PLDs and larger FPGAs — confirm your LUT, RAM and DSP utilization against the family table before committing, and for MIPI CSI-2 sensor bridging check the Lattice embedded-vision reference designs. Parameters verified against Lattice Semiconductor documentation and distributor listings.
