Abstract
A circuit device includes a physical layer circuit coupled to a data bus, and a processing circuit that controls the physical layer circuit and performs communications processing through the data bus. The processing circuit operates with a voltage supplied from a ground line as a power supply voltage VSS on a low potential side, and the physical layer circuit operates based on a power supply voltage VSSA on the low potential side supplied from a power supply line not coupled to the ground line in the circuit device, and a power supply voltage HVDDA on a high potential side set with reference to the power supply voltage VSSA.
