Abstract
To realize an optimal power-on reset in a system in which the rise of the power supply voltage is sharp. A semiconductor device according to the present invention includes two diodes connected in parallel between power supplies, and a resistor circuit and a capacitance element connected in parallel between one power supply and each of the two diodes, and outputs a comparison result between voltages outputted from the two resistor circuits as a reset signal.
