The present disclosure provides a serial communication device. The device includes: a first interface module communicatively coupled to an advanced bus of a master machine, a second interface module communicatively coupled to a data interface of a slave machine, a control module, a transceiving enable module, a shift register module and an interrupt generating module. The shift register module acquires through the first interface module data to write that is sent by a master machine, and serially shifts out the data to write when a shift enable signal is valid, the serial data that is shifted out being sent to a slave machine through the second interface module; and the shift register module acquires through the second interface module serial data that is uploaded by the slave machine, serially shifts in the serial data when the shift enable signal is valid, and obtains data to read according to the serial data that is shifted in, the data to read being uploaded to the master machine through the first interface module. The present disclosure can save resources consumed during serial communication of the master machine.
