Abstract
An electronic control unit includes a microcomputer, a power supply IC and a peripheral circuit part. The microcomputer includes a core operable with a first power supply voltage and an input/output circuit operable with a second power supply voltage higher than the first power supply voltage. The power supply IC generates the first power supply voltage and the second power supply voltage. The peripheral circuit part has a first input terminal for the first power supply voltage, a second input terminal for the second power supply voltage, and an internal circuit operable with a potential between the first power supply voltage and the second power supply voltage. A core input terminal for the first power supply voltage, a first output terminal for the first power supply voltage in the power supply IC and the first input terminal are electrically connected one another.
