    • The semiconductor integrated circuit is provided, in which an external temperature control or temperature monitoring is possible, with little influence by the noise of a system board which mounts the semiconductor integrated circuit. The semiconductor integrated circuit includes the temperature detection circuit which detects the chip temperature, and the functional module which flows a large operating current. An external terminal which supplies operating voltage, and an external terminal which supplies ground voltage are coupled to the functional module. The temperature detection circuit generates a temperature detection signal and a reference signal. The reference signal and the temperature detection signal are led out to the exterior of the semiconductor integrated circuit via a first external output terminal and a second external output terminal, respectively, and are supplied to an external temperature control/monitoring circuit which has a circuitry type of a differential amplifier circuit.
