CH341 DataSheet 1 USB Bridge Controller CH341 DataSheet Version: 3C http://wch.cn 1. Introduction CH341 is a USB converter chip, which converts USB to serial UART interface, printer interface, parallel port interface, and common 2/4-wire synchronize serial communication interfaces etc. In UART mode, CH341 provides UART transmit enable, UART receive ready rate control signals ,etc., and common MODEM interface signals, to expand UART interface of computer or upgrade common serial interface devices to USB directly. In print port mode, CH341 provides a standard USB print port compatible with USB-related specifications and the Windows operating system for upgrading a print port printer directly to the USB. In parallel port mode, CH341 provides an 8-bit parallel interface in EPP mode or MEM mode for input and output data directly without a microcontroller/DSP/MCU. In addition, CH341B/F/A support commonly used synchronous serial interface such as 2-wire interface (SCL line, SDA line) and 4-wire interface (CS line, SCK/CLK line, MISO/SDI/DIN Line, MOSI/SDO/DOUT line), etc. UART/RS232/RS485/RS422 Computer or other USB host USB CH341 Bridge Convert to USB Printer EPP and MEM Parallel port 2 and 4-wire serial interface 2. Features 2.1. Introduction ● Full speed USB device interface, USB 2.0 compatible. ● Supports 5V and 3.3V power supply. ● Optional: customize the vendor ID, product ID, serial number, etc. via an external low-cost serial EEPROM. ● Low cost, convert the original serial port peripheral devices, the original print port printer, and the original parallel port peripheral devices to USB directly. ● RoHS compliant SOP-28, SSOP-20 and QFN28 lead-free package. ● Only compatible with the applications, and cannot be absolutely the same. 2.2. UART ● Emulate standard UART interface, used to upgrade the original serial devices or expand additional UART via USB. ● Original UART applications are totally compatible without any modification.
