Abstract
To provide a semiconductor device provided with a power-on reset circuit that can reliably detect decrease in power-supply voltage. The power-on reset circuit provided on the semiconductor device includes: a first comparison circuit that compares a primary voltage with a reference value; and a second comparison circuit that compares a secondary voltage with the reference value. The power-on reset circuit issues a reset signal based on comparison results of the first and second comparison circuits.
