Abstract: A semiconductor device is provided which can detect a fluctuation of a power supply voltage. The semiconductor device includes a counter circuit that outputs a signal when a period during which a power supply voltage of a system to be monitored is lower than or equal to a first voltage value exceeds a predetermined time, a first flag circuit that sets a first flag based on the signal, a second flag circuit that sets a second flag when the power supply voltage becomes a second voltage value or lower, and a circuit that outputs a reset signal that resets the system when both the first and the second flags are set. The first voltage value and the second voltage value are higher than a minimum voltage that guarantees normal operation of the system. The first voltage value is higher than the second voltage value.
