An interface module and a method for synchronizing clock signals and transmitting and receiving data are provided to transmit and receive a control signal between components of the interface module in synchronization with operating clock signals of the components and stabilize data signals when the interface module exchanges the data signals in a slave mode. An interface module includes a transmission controller(211) and a transfer unit(240). The transmission controller operates in response to a first clock signal and outputs data inputted from a central processing unit. The transfer unit operates in response to a second clock signal and sequentially outputs data inputted from the transmission controller to a peripheral device. The transmission controller and the transfer unit respectively include synchronization units(411,241) for converting a control signal transmitted and received between the transmission controller and the transfer unit according to operating clock signals of the transmission controller and the transfer unit.
