POWER SUPPLY CONTROL DEVICE |
摘要 |
An object is to reduce standby power in a data processing device, without loss of convenience, in a structure in which a power supply control device includes the data processing device. In a structure of a power supply control device which supplies power to an external device using a main switch, a data processing device is provided in the power supply control device to control the main switch; a sub-switch supplying power to the data processing device is provided; and a volatile memory unit and a nonvolatile memory unit are provided in the data processing device. Further, the sub-switch is off in a period in which data is stored in the nonvolatile memory unit of the data processing device, so that power supply to the data processing device is intermittently stopped. |
