The 81-WLCSP package (3.80x3.69 mm) keeps the footprint small enough for space-constrained portable or embedded designs where board real estate is the limiting factor. ## WLCSP package — layout and integration The 81-WLCSP (Wafer-Level Chip-Scale Package) with a 3.80x3.69 mm body and 0.50 mm typical ball pitch demands a controlled-impedance PCB stack-up and careful fan-out for the 63 I/O. The supplier device package is 81-WLCSP (3.80x3.69), so the footprint matches standard Lattice MachXO3 WLCSP land patterns.","metaTitle":"Lattice LCMXO3LF-4300E-5UWG81CTR1K FPGA, 4320 LEs, 63 I/O","metaDescription":"Lattice MachXO3 FPGA, 4320 logic elements, 63 I/O, 94 Kbit RAM, 1.14-1.26V, 0-85°C, 81-WLCSP.
