Disclosed are a circuit, method, and device for waking up a main microcontroller unit (MCU), thus allowing the main MCU of a device to wake up in a timely manner from a deep sleep to transmit and receive data. The method comprises: configuring an MCU into a deep sleep state, configuring a peripheral processing chip and a peripheral interface chip into a normal working state (S201); monitoring the volume of data transmitted by the peripheral processing chip to the peripheral interface chip (S202); and, when the data volume exceeds a threshold value, transmitting a wakeup signal to the main MCU (S203). The method allows the main MCU of the device to wake up from a deep sleep to transmit and receive data. |
