CH340 Datasheet (I) 1 USB to Serial Port Chip CH340 Datasheet Version: 3B http://wch.cn 1. Introduction CH340 is a USB bus converter chip which converts USB to serial port or printer port. In UART mode, CH340 provides standard MODEM signals, used to extend serial port for computers, or upgrade directly from normal serial device to USB bus. For more information about converting USB to printer interface, please refer to the CH340DS2 datasheet. Computer USB or Other USB Host CH340 UART/RS232/RS485 Convert Parallel Printer to USB Printer 2. Features l Full-speed USB device interface, USB 2.0 compatible. l Emulate standard UART interface, used to upgrade the original serial peripheral or expand additional UART via USB.
