CH340G (SMD SOP-16 Package) USB to Serial TTL Converter IC

CH340 is a series of USB bus adapters, that provides serial, parallel or IrDA interfaces over the USB bus (note: CH340G supports serial interface only). The CH340G integrate circuit provides common MODEM signals to allow adding a UART to a computer or converting existing UART devices to USB interface. Features:- • Full-speed USB interface, compatible with USB 2.0 interface. • Operates with a minimum amount of external components: a crystal and a minimum of four capacitors. • Provides a virtual serial port for upgrading existing serial port devices or adding serial ports to a PC. • Supports all existing applications using serial ports without the need of changing existing code. • Hardware full-duplex serial interface with internal FIFO. Baud rate range from 50bps to 2Mbps. • Supports common flow control signals RTS, DTR, DCD, RI, DSR and CTS. • Supports RS232, RS422 and RS485 with external level shifting components.
