The exposed paddle (if present on this variant) is not a thermal pad; the part's static power is low enough that a standard QFP footprint without thermal vias is adequate.","metaTitle":"Lattice LCMXO256C-3TN100I FPGA, 256 LUTs, 78 I/O, 100-TQFP","metaDescription":"Lattice MachXO LCMXO256C-3TN100I FPGA: 256 LUTs, 78 I/O, 1.71-3.465 V, -40°C to 100°C, 100-TQFP.
