CDC RS 232 EMULATION DEMO DRIVER WINDOWS 7 SERIAL

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.

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 serial UART interface, integrated transmit-receive buffer, supports communication baud rate varies from 50bps to 2Mbps.Original serial applications are totally compatible without any modification in Windows operating systems.Emulate standard UART interface, used to upgrade the original serial peripherals or expand additional serial 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 serial port mode, CH340 provides standard MODEM signals, used to extend UART for computers, or upgrade directly from normal serial port device to USB bus. CH340 is a USB bus converter chip which converts USB to serial port or printer port.
