Abstract
The reset function incorporated microcomputer of the present invention, capable of suppressing a variation in reset voltage with a simple configuration, includes a reset decision section. In the reset decision section, a band gap reference circuit generates a predetermined reference voltage VA. A voltage dividing resistance generates a reset voltage VR from the reference voltage VA. A comparator compares the supply voltage VDD applied to the microcomputer with the reset voltage VR, and outputs a reset signal SR.
