Working Principles

The SC16C852LIBS,151 is a serial communication controller that enables reliable and efficient data transfer between devices. It utilizes UART (Universal Asynchronous Receiver Transmitter) technology to transmit and receive data in a serial format. The dual UART feature allows simultaneous communication on two channels.

The integrated FIFOs help in reducing the CPU overhead by storing incoming and outgoing data temporarily. This ensures smooth and uninterrupted data flow. The controller also supports hardware flow control using RTS/CTS signals, preventing data loss due to buffer overflow.

The SC16C852LIBS,151 can operate in full-duplex or half-duplex modes, depending on the application requirements. It supports both RS-232 and RS-485 protocols, making it suitable for a wide range of serial communication applications.
