Working Principles

The ST16C550CQ48TR-F is an integrated circuit that functions as a serial communication controller. It facilitates the exchange of data between microcontrollers and peripheral devices using the UART protocol. The UART functionality allows asynchronous serial communication, enabling devices to transmit and receive data without requiring a common clock signal.

The IC operates at a maximum data rate of 1.5 Mbps and supports both full-duplex and half-duplex communication modes. It incorporates hardware flow control using Clear To Send (CTS) and Request To Send (RTS) signals, ensuring reliable data transmission by preventing data overflow or loss.

Programmable interrupt sources enable efficient data handling, allowing the microcontroller to respond promptly to incoming data or events. The IC also features 16-byte transmit and receive FIFO buffers, which enhance data throughput and reduce the burden on the microcontroller's processing unit.
