Definition of "UART" |
Universal Asynchronous Receiver-Transmitter: An IC that converts parallel data to serial, for transmission; and converts received serial data to parallel data. See: UART-related application notes / Universal Asynchronous Receiver-Transmitter, / A universal asynchronous receiver/transmitter, is a piece of computer hardware that translates data between parallel and serial forms. universal asynchronous receiver/transmitter are commonly used in conjunction with communication standards such as EIA, RS-232, RS-422 or RS-485. The universal designation indicates that the data format and transmission speeds are configurable. The electric signaling levels and methods (such as differential signaling etc.) are handled by a driver circuit external to the UART. The first UART was invented by Gordon Bell for the PDP-1. / Universal Asynchronous Receiver/Transmitter is the microchip with programming that controls a computer's interface to its attached serial devices. Specifically, it provides the computer with the RS-232C Data Terminal Equipment interface so that it can talk to and exchange data with modems and other serial devices. / A UART (Universal Asynchronous Receiver/Transmitter) is the microchip with programming that controls a computer's interface to its attached serial devices. Specifically, it provides the computer with the RS-232C Data Terminal Equipment ( DTE ) interface so that it can "talk" to and exchange data with modems and other serial devices. As part of this interface, the UART also Converts the bytes it receives from the computer along parallel circuits into a single serial bit stream for outbound transmission On inbound transmission, converts the serial bit stream into the bytes that the computer handles Adds a parity bit (if it's been selected) on outbound transmissions and checks the parity of incoming bytes (if selected) and discards the parity bit. / A Remote Terminal Unit is an electronic device that is controlled by a microprocessor. The device interfaces with physical objects to a Distributed Control System or Supervisory Control and Data Acquisition system by transmitting telemetry data to the system. / See universal asynchronous receiver transmitter. |
