Part number : CH340G
Function : USB to UART Interface ( USB Interface Integrated Circuit )
Package information : SOIC 16 Pin
Manufacturer : WCH ( DreamCity Innovations )
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.
1. Full-speed USB interface, compatible with USB 2.0 interface.
2. Operates with a minimum amount of external components: a crystal and a minimum of four
3. Provides a virtual serial port for upgrading existing serial port devices or adding serial ports
to a PC.
4. Supports all existing applications using serial ports without the need of changing existing
5. RoHS-compliant narrow body SO-16 package.
