摘要： A temperature sensor in a semiconductor device includes a temperature detection circuit for outputting a voltage according to the chip temperature, a reference voltage generating circuit for generating a plurality of reference voltages, and a plurality of voltage comparators for comparing each reference voltage with an output voltage of the temperature detection circuit and thereby generating a chip temperature detection signal configured with multiple bits. Further, the temperature sensor includes a control circuit for controlling the reference voltages generated by the reference voltage generating circuit based on the chip temperature detection signal and thereby changing correspondence between the chip temperature detection signal and the chip temperature to shift a chip temperature detection range. It is possible to expand the chip temperature detection range by changing the correspondence between the chip temperature detection signal and the chip temperature, without increasing the number of voltage comparators.

摘要： 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.
