1 CH343 Datasheet USB to High-Speed Serial Chip CH343 Datasheet Version: 1E http://wch.cn 1. Introduction CH343 is a USB bus converter chip, which converts USB to high-speed serial UART interface , supports automatic identification and dynamic adaptation of communication baud rate of 115200bps and below, provides common MODEM signal, to expand serial UART interface of computer or upgrade common serial devices or MCU to USB bus directly. VDD5 Computer or other USB host UD+、UD- VIO CH343 convert chip UART/RS232/RS485 2. Features l Full-speed USB device interface, USB 2.0 compatible. l Built-in firmware , emulate standard UART interface, used to upgrade the original serial peripherals or expand additional serial UART via USB. l Original serial applications are totally compatible without any modification. l Supports free installation OS which built-in CDC driver or multifunctional high-speed VCP vendor driver. l Hardware full-duplex serial UART interface, integrated independent transmit-receive buffer, supports communication baud rate varies from 50bps to 6Mbps. l Supports automatic identification and dynamic adaptation of common communication baud rate of 115200bps and below. l Supports 5, 6, 7 or 8 data bits, supports odd, even, space, mark and no parity. l Supports common MODEM interface signals RTS, DTR, DCD, RI, DSR and CTS. l Supports CTS and RTS hardware automatic flow control. l Supports half-duplex, provides sending status TNOW which support RS485 to switch. l Supports RS232 interface, through external voltage conversion chip. l Supports USB port 5V and 3.3V power supply. l I/O independent power supply, supports 5V, 3.3V, 2. 5 V and 1.8V power supply. l Integrated power-on reset, integrated 12MHz clock, no external crystal required. l CH343P integrates EEPROM used to configure the chip of VID, PID, maximum current value , vendor and product information string, etc. l Chip has integrated Unique ID (USB Serial Number). l RoHS compliant SOP-16, ESSOP-10 and QFN16 lead-free package.
