Abstract
The present invention provides a semiconductor device having a sensor capable of improving precision while suppressing increase in occupation area. A semiconductor device has: a first counter; and a second counter (time measuring circuit) measuring time until a count value, which is obtained by counting a first signal having a frequency corresponding to a first voltage, reaches a largest count value which can be counted by the first counter. The first counter obtains a piece of digital information corresponding to the first voltage on the basis of a count value obtained by counting a second signal having a frequency corresponding to a second voltage, which is different from the first voltage, on the basis of the time measured by the time measuring circuit.
