CH340
Features l Full-speed USB device interface, USB 2.0 patible. l Emulate standard UART interface, used to upgrade the original serial peripheral or expand additional UART via USB. l Original UART applications are totally patible without any modification in Windows operating systems. l Hardware full duplex UART interface, integrated transmit-receive buffer, supports munication baud rate varies from 50bps to 2Mbps. l Supports mon MODEM interface signals RTS, DTR, DCD, RI, DSR and CTS. l Provides further RS232, RS485, RS422 interface, etc. through external voltage conversion chip. l CH340R supports Ir DA criterion SIR infrared munication, supports baud rate varies from
2400bps to 115200bps. l Built-in firmware, software patible with CH341, use VCP driver of CH341 directly. l Supports 5V and 3.3V power supply voltages. l CH340C/N/K/E/X/B have integrated clock, no external crystal required, CH340B also integrates
EEPROM used to configure the serial number, etc. l Ro HS pliant SOP-16, SOP-8,...
