Semiconductor device and method for supplying power supply voltage to semiconductor device

摘要

A semiconductor device that includes a first power supply terminal supplied with a first power supply voltage, a second power supply terminal supplied with a second power supply voltage, and a third power supply terminal supplied with a third power supply voltage. The semiconductor device also includes a first terminal being connectable to a host device and a second terminal being connectable to a peripheral device. The semiconductor device also includes a first circuit block connected to the first terminal and the first power supply terminal and receiving a data outputted from the host device based on the first power supply voltage, a second circuit block connected to the second terminal and the third power supply terminal and receiving a data outputted from the peripheral device based on the third power supply voltage, and a third circuit block connected to the second power supply terminal and controlling operation of the first circuit block and the second circuit block based on the second power supply voltage.
