Drivers support for Windows/Linux/Android/Mac, etc. Used to distribute to user with the product.ĬH341 datasheet, USB bus converter chip with multiple communication interfaces, such as USB to serial port/parallel port/printer port/I2C interface etc. The USB transceiver of CH340 is designed according to the built-in design of USB2.0, and it is recommended that no external resistor is in series with UD+ and UD- pins.ĬH340/CH341 USB to serial port Windows driver, supports Windows XP/Vista/7/8/8.1/10/11/ SERVER 2003/2008/2012/2016/2019/2022 -32/64bit, Microsoft WHQL Certified, supports USB to 3-line and 9-line serial port. The EPAD of CH340K is 0# pin (GND), which is an optional connection the 3# pin (GND) is the necessary connection.ĬH340X is improved based on CH340E, with 5V tolerant characteristic added when the power supply is 3.3V.Ħ# pin of CH340X can be changed from TNOW to DTR# when an external resistor is connected, see Section 5.3 for the two configurations.ĬH340C whose batch number begins with 4 and last 3-digit greater than B40, 8# pin can be changed to DTR# when a 4.7KΩ pull-down resistor is connected.ĬH340R provides reverse polarity TXD and MODEM interface signals, discontinued.

RoHS compliant SOP-16, SOP-8, SSOP-20 and ESSOP-10, MSOP-10 lead-free package.ĬH340C, CH340N, CH340K, CH340E, CH340X and CH340B have integrated clock, no external crystal required.ĬH340B has integrated EEPROM used to configure serial number, some functions can be customized, etc.ĬH340K has 3 built-in diodes to reduce current flow backwards between the I/O pins of the MCU.

CH340C/N/K/E/X/B have integrated clock, no external crystal required, CH340B also integrates EEPROM used to configure the serial number, etc.

Supports 5V and 3.3V power supply voltages.

Built-in firmware, software compatible with CH341, use VCP driver of CH341 directly.

CH340R supports IrDA criterion SIR infrared communication, supports baud rate varies from 2400bps to 115200bps.

through external voltage conversion chip.

Provides further RS232, RS485, RS422 interface, etc.

Supports common MODEM interface signals RTS, DTR, DCD, RI, DSR and CTS.

Hardware full duplex UART interface, integrated transmit-receive buffer, supports communication baud rate varies from 50bps to 2Mbps.Original UART applications are totally compatible without any modification in Windows operating systems.

#CH341SER USB DRIVER MAC UPGRADE#

Emulate standard UART interface, used to upgrade the original serial peripheral or expand additional UART via USB.

Full-speed USB device interface, USB 2.0 compatible.

For more information about converting USB to printer interface, please refer to the CH340DS2 datasheet. 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. CH340 is a USB bus converter chip which converts USB to serial port or printer port.
