Semiconductor integrated circuit device
A semiconductor integrated circuit device provided with a first circuit block BLK1, a second circuit block DRV1 and a conversion circuit MIO1 for connecting the first circuit block to the second circuit block. The first circuit block includes a first mode for applying a supply voltage and a second mode for shutting off the supply voltage. The conversion circuit is provided with a function for maintaining the potential of an input node of the second circuit block at an operation potential, thereby suppressing a penetrating current flow when the first circuit block is in the second mode. The conversion circuit (MIO1 to MIO4) are commonly used for connecting circuit blocks.
