Abstract
A circuit device includes an oscillation circuit that generates an oscillation signal by using an resonator, a processing circuit that controls the oscillation circuit, and a storage circuit that stores temperature compensation data of an oscillation frequency of the oscillation signal. The processing circuit generates specific PUF information of the circuit device on the basis of the temperature compensation data.
