A microcomputer that comprises a standby signal generating circuit for supplying a standby signal to a processor and an initial reset circuit for supplying an initial reset signal to the processor when supply voltage becomes lower than a predetermined value, wherein the standby signal is produced in either case where a standby condition is sustained or imposed to switch the processor from an operation mode to a standby mode so that the supply voltage may be lowered during the standby mode, is characterized by the provision of a blocking circuit for blocking the entrance of the initial reset signal into the processor according to the standby signal thus produced.
