BYU. â¢ A UART may be used when: âHigh speed is not required. âA cheap communication line between two devices. is required. â¢ Asynchronous serial communication is very cheap. âRequires a transmitter and/or receiver. âSingle wire for each direction (plus ground wire) âRelatively simple hardware.
When PCs all had parallel bus architecture, the UART's purpose was to convert bytes from the PC's parallel bus to a serial bit-stream. The cable going out of the serial port is serial and has only one wire for each direction of flow. The serial port sends out a stream of bits, one bit at a time.
