The 63 I/O fan out from the centre array; a four-layer board with microvias is the standard approach for this ball pitch. ## Logic density and memory headroom 4320 logic cells arranged in 540 LABs/CLBs, backed by 94 Kbit of embedded RAM. The 1.14 V to 1.26 V core supply means the device runs from a single 1.2 V rail — no separate VCCIO for the core. The 63 user I/O are banked and can be assigned to different I/O standards within the same supply range. Marked as Active by Lattice, with ROHS3 compliance.","metaTitle":"LCMXO3L-4300E-5UWG81CTR1K MachXO3 FPGA, 4320 LEs, 63 I/O","metaDescription":"Lattice MachXO3 FPGA, 4320 logic cells, 63 I/O, 94 Kbit RAM, 1.14-1.26 V core, 81-WLCSP.

Both share the same 4320 logic cells, 63 I/O, 94 Kbit RAM, and 81-WLCSP footprint — they are pin-compatible and drop into the same board layout.
