Abstract
An environmental power generation device outputs power generation charges to a power supply line to which a capacitor is connected. When a power generation voltage corresponding to a charging voltage for the capacitor is equal to or higher than an power-on criterion voltage, a voltage comparison circuit outputs a voltage detection signal. An internal circuit of a semiconductor device is powered on in response to the voltage detection signal. A setting change circuit switches the power-on criterion voltage in accordance with a setting input.
