Abstract
A UART having an IC card reading interface comprises a universal asynchronous communication core, a multiplexer and a 3-state control I/O buffer. The universal asynchronous communication core is responsible for an asynchronous serial communication. The multiplexer and the 3-state control I/O buffer enable serial output signal and serial input signal pins have different functions during an IC card reading mode and a universal asynchronous receive/transmit mode. An IC card reading system includes an IC card reader having an IC card socket and a smart card interface and a computer system having the UART with the IC card reading interface. Since the UART with an IC card reading interface can be directly electrically connected to the smart card interface of the IC card reader, a micro-controller and a receiver-transmitter can be saved in the IC card reader.
