Overview

DreamCity Innovations WCH CH340G Datasheet WCH CH340 Series USB Interface Integrated Circuit CH340G USB to UART Interface Datasheet WCH Version 1E DreamCity Version 1.0 Disclaimer from DreamCity Innovations This is a third-party translation of WCH’s CH340 Series chipset’s Chinese datasheet, with information regarding CH340G chip extracted.

The two other chips sharing the same datasheet, CH340R and C340T, have official English version.

Overview 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.

Key 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.
