4320 logic cells in a 3.8 x 3.69 mm WLCSP
The LCMXO3L-4300E-5UWG81ITR1K is a Lattice MachXO3 FPGA packing 4320 logic cells and 540 LABs/CLBs into an 81-ball WLCSP measuring 3.80 x 3.69 mm — a footprint that fits behind a camera module or inside a handheld enclosure where board real estate is the binding constraint. With 63 user I/O and 94 Kbit of embedded RAM, this device bridges the gap between glue-logic CPLDs and larger FPGAs: enough LUTs for a 16-bit RISC core plus peripheral decode, yet small enough to route on two-layer boards when the fan-out is planned around the WLCSP ball map.
Industrial temperature grade and core supply
The core operates from 1.14 V to 1.26 V — a tight 1.2 V nominal rail that keeps dynamic power low but demands a clean supply: a 1.0 A LDO with 50 mV dropout and 1% accuracy covers the tolerance without overshooting the abs-max.
