PROBLEM TO BE SOLVED: To provide a semiconductor integrated circuit which can cope with temperature change in a wide range without needing a peripheral device. SOLUTION: The semiconductor integrated circuit 1 is provided with a temperature sensing circuit 6 for measuring a temperature of the circuit 1, a plurality of blocking circuits 4, 5 classified by temperature whose circuit functions adapted for different temperature range are identical, a common temperature blocking circuit 3 which is adapted for all of the different temperature ranges, and an operation blocking switching control circuit 7 which operates one blocking circuit classified by temperature out of the plurality of blocking circuits 4, 5 by a temperature measured with the sensing circuit 6, and stops the operation of the residual blocking circuits which are not selected.
