ABSTRACT:
In a semiconductor integrated circuit device, a first control signal outputted from the power voltage evaluation circuit controls power voltage of the power voltage generation circuit so that the power voltage becomes lower within a range over which the internal circuit normally operates, while a second control signal outputted from the specified voltage detection circuit controls the power voltage of the power voltage generation circuit so that the power voltage generated by the power voltage generation circuit does not become equal to or higher than a specified voltage. This makes the power voltage as low as possible within the normally operational range of the internal circuit and suppresses increase of the gate current, so that unstable operations and current consumption increase of the MOS transistor can be prevented.
