A programmable logic circuit device has a plurality of logic blocks, a plurality of routing wires, a plurality of switch circuits, a plurality of connection blocks, and an I/O block performing an input/output operation with external equipment. The routing wires are connected to each of the logic blocks, the switch circuits are provided at an intersection of each of the routing wires, and the connection blocks are provided between an I/O line of each of the logic blocks and each of the routing wires. Each of the logic blocks has a look up table of M inputs and N outputs, which has a plurality of LUT units; and an internal configuration control circuit controlling an internal configuration of the plurality of LUT units.
