It is able to transmit across longer cables and at higher transmission rates, making it preferred. USB is used for many consumer products and for industrial applications as well. It is in wide use as a serial transmission format because of its elegance. USB uses a transmission protocol that requires far fewer pins to communicate. Older serial transmission ports require compatible hosts The data from UART is compatible with RS-232, RS-422, and RS-485 transmission schemes which are commonly used in industrial equipment. The older transmission protocols defined transmit and receive pins, as well as control pins to accommodate handshaking between host and slave devices. UART converts both parallel and serial data on circuit boards in a form that can be used by older protocols. Transmission of serial bits takes a different form in the older protocol transmissions of RS-232, RS-422, and RS-485, so converters exist to bridge the gap from old equipment to new. However, there continue to exist abundant equipment that uses older forms of serial ports. USB is a universal serial bus and continues to gain popularity as the best form of serial transmission in digital products. Otherwise, both the size and cost of modern electronics would be excessive. Parallel bytes take up too much real estate, so serial formats for transmitting data are the preferred form in today’s digital age. This type of IC is commonly found on motherboards where CPUs output data in byte format. UART is a universal asynchronous receiver/transmitter and is an integrated circuit used to convert parallel bytes into serial bit streams. These types of interfaces are commonly used for communication with hardware peripherals in digital systems. UART interfaces are commonly known as RS-232, RS-422, or RS-485. A USB to UART converter is an integrated circuit used to send or receive serial data from a USB port into serial data that can be received or sent by a UART interface. ![]()
