Universal Asynchronous Receivers & Transmitters

Universal Asynchronous Receiver-Transmitter, more commonly referred to as UART, is a type of serial communication interface. UART’s primary function is to transmit and receive data via a data bus. It allows two devices, such as computers, to carry out data transmission over a wired connection. UARTs convert incoming and outgoing data bytes into a serial bit stream.


These particular UARTs are stand-alone integrated circuits (ICs). However, you can also find UARTs within microcontrollers (MCUs).


UART ICs (integrated circuits) are semiconductor devices which can be integrated into your electronics designs to enable UART communication. UART is a popular method of communication in electronics projects. It enables computer hardware to communicate with other modems and serial devices.


When choosing a UART IC, ensure that it meets the requirements of the modem transmission rate.



What does a UART consist of?


One side of the UART feature around 8 data lines and the control pins. The other side of the UART has two serial wires, the Transmission (TX) and the Receiving (RX).



Communication Standards


UARTs may feature a communication standard which defines the signals between devices. These standards include RS-232, RS-422 and RS-485.



What is baud rate?


UART baud rate is the speed at which the data is transferred which is given in bits per second (bit/s or bps). The devices that you are communicating between should both have the same baud rate.



What does Asynchronous mean?


Asynchronous is a type of serial communication where the interfaces at each end are not synchronised by a common clock signal.



What is USART?


USART is very similar in functionality to a UART device. However, it also offers the possibility of a “synchronous” mode.
