Working Principles

The SC16C852LIBS,128 is an integrated circuit designed to facilitate serial communication between devices. It consists of two independent UART channels, each equipped with a 128-byte FIFO buffer. The device operates based on the principles of asynchronous serial communication, where data is transmitted in a sequential manner.

When data is received, it is stored in the respective UART's FIFO buffer. The data can then be read by the microcontroller or another device connected to the SC16C852LIBS,128. Similarly, when data needs to be transmitted, it is written to the FIFO buffer and sent out through the appropriate UART channel.

The device supports various data formats, baud rates, and flow control mechanisms, providing flexibility for different application requirements.
