Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a semiconductor integrated circuit device for a temperature compensation type oscillator realizing a minimum number of terminals required for an oscillation operation by a low power consumption. SOLUTION: The semiconductor integrated circuit device has a power-supply voltage terminal, a grounding terminal, a first terminal and a second terminal for connecting a crystal, an oscillation-frequency output terminal, and a voltage-control terminal. The voltage-control terminal is supplied with a voltage signal exceeding a voltage range allocated for controlling a frequency and also used for inputting a clock signal and an operating-mode signal. The oscillation-frequency output terminal is used as a command input for setting an operation mode by the operation-mode signal and the clock signal and a signal input or a signal output under the internal state decipherring a command.
