  • One-chip semiconductor device incorporating a power-supply-potential detecting circuit with reset function
    Patent number: 4551841
    Abstract: A one-chip semiconductor device, such as a one-chip microcomputer, includes a power-supply-potential detecting circuit (9) which, when the power supply potential (V.sub.CC) becomes lower than a predetermined value (V.sub.D), generates a reset signal (RST) to reset, i.e., initialize the one-chip device. A reset signal inhibiting circuit (10, 11) is provided to inhibit the transmission of the reset signal during the check mode.
