Working Principles

The TL16C2550RHBRG4 operates based on the principles of UART communication. It converts parallel data into serial format for transmission and vice versa. When transmitting data, the IC encodes the parallel data into a serial bit stream and transmits it through the TXD (Transmit Data) pin. On the receiving end, the IC decodes the received serial data into parallel format and provides it through the RXD (Receive Data) pin.

The UART communication is asynchronous, meaning that there is no clock signal shared between the transmitter and receiver. Instead, start and stop bits are used to synchronize the data transmission. The TL16C2550RHBRG4 supports various data formats, including different data lengths, parity modes, and stop bit configurations, providing flexibility in different communication scenarios.
