Working Principles

The TL16C2550IPFB operates based on the principles of UART communication. It receives and transmits serial data using asynchronous communication protocols. The integrated circuit converts parallel data from the host device into a serial format for transmission and vice versa.

When receiving data, the IC synchronizes the incoming serial stream with its internal clock to extract the transmitted bits. It then reconstructs the original parallel data for further processing by the host device. During transmission, the IC converts parallel data into a serial stream and transmits it at the specified baud rate.
