What are UARTs (Universal Asynchronous Receiver Transmitter) ?
UARTs (Universal Asynchronous Receiver Transmitter) are integrated circuits that enable asynchronous serial communication by converting parallel data into a serial format for transmission. They are widely used in applications such as wireless and RF signal chains, new product design, and maintenance of electronic systems. Important specifications for selection include Data Rate (Max), which affects the speed of data transfer; Protocol, which determines the communication standard; and Voltage, which ensures compatibility with the power supply. Procurement teams should validate lifecycle status and consider alternate-source options to mitigate sourcing risks.
