CH342 Datasheet 1 USB to Dual Serial Ports Chip CH342 Datasheet Version: 1E http://wch.cn 1. Introduction CH342 is a USB bus converter chip, which converts USB to dual UART. Each UART supports high-speed full-duplex and odd/even parity, provides standard MODEM signals, used to expand serial ports for computer or upgrade directly from normal serial device or MCU to USB bus. Computer or Other USB Host VDD5 USB CH342 0# UART/RS232/RS485 VIO 1# UART/RS232/RS485 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. l Original serial applications are totally compatible without any modification in Windows operating systems.
