Working Principles

The SC26C92A1A,518 is based on the UART principle, which stands for Universal Asynchronous Receiver/Transmitter. It provides a reliable and efficient means of serial communication between devices. The chip converts parallel data into serial format for transmission and vice versa.

The working principle involves receiving data through the RXD (Receive Data) pin, which is then stored in the receive FIFO buffer. Similarly, data to be transmitted is stored in the transmit FIFO buffer and sent out through the TXD (Transmit Data) pin. The chip handles various aspects of data communication, including baud rate generation, flow control, and interrupt handling.
