ABSTRACT:
A universal asynchronous receiver/transmitter (UART) circuit for a mobile telecommunication terminal is disclosed. In one embodiment, the UART circuit includes a first universal asynchronous receiver/transmitter (UART1) and a second universal asynchronous receiver/transmitter (UART2) coupled to a processor, configured to receive and transmit data between the mobile telecommunication terminal and an external device. The UART circuit also includes a hands-free functional part coupled to the processor, configured to perform signal processing. The UART circuit also includes a multiplexer coupled to the hands-free functional part and the UART2at respective receiving and transmitting ends, configured to perform switching operations based on at least one control signal transmitted from the processor. The UART circuit also includes a multi-pin receptacle coupled to the multiplexer, configured to interface with the external device. The present invention enables the multi-pin receptacle and the two universal asynchronous receiver/transmitters to be used simultaneously.
