Working Principles

The SC16C550BIA44,518 operates as a serial communication controller by implementing the Universal Asynchronous Receiver/Transmitter (UART) protocol. It receives and transmits data in a serial format, converting parallel data from the host system into serial data for transmission and vice versa.

The UART utilizes a clock signal to synchronize the data transfer between the sender and receiver. The SC16C550BIA44,518 incorporates a programmable baud rate generator, allowing the selection of various standard and non-standard data rates.

The built-in FIFOs help in buffering the incoming and outgoing data, reducing the load on the host system and improving overall performance.
