CH340G Description

Short technical summary and product information.

The WCH CH340G is an integrated circuit designed to provide a USB to serial (UART) interface. It is compatible with USB 2.0 full-speed operation and requires minimal external components, such as a crystal and capacitors, for functionality.

 

This IC offers a virtual serial port, allowing existing serial port applications to be used without code modification. It supports hardware full-duplex serial communication with internal FIFO buffers and a wide baud rate range from 50 bps to 2 Mbps. The CH340G can operate at either 3.3V or 5V, providing flexibility for different system requirements. It also supports common modem flow control signals.

 

The CH340G is available in a RoHS-compliant narrow body SO-16 package, suitable for surface mounting. Its ability to convert existing UART devices to USB interface makes it a valuable component for embedded systems and PC peripheral development.
