CH340G SMD IC Transceiver USB 2.0 2Mbps SOP-16

From the shop's description

Introduction CH340 is a USB bus conversion chip, it can realize USB to UART interface or USB to printer interface. In serial UART mode, CH340 provides a common MODEM liaison signal, used to expand the UART interface of the computer or upgrade the common serial device to a USB bus directly. For more information on USB conversion to printer interface please refer to the manual CH340DS2. Features Full-speed USB device interface, compatible with USB V2.0. Emulate standard UART interface, used to upgrade the serial peripherals, or expand UART interface via USB bus. Original serial applications are compatible, without any modification in the Windows operation system. Hardware full duplex serial UART interface, built-in transmit-receive buffer, supports communication baud rate varies from 50bps to 2Mbps. Supports common MODEM liaison signal RTS, DTR, DCD, RI, DSR, and CTS. Through external level conversion chip provide further RS232, RS485, RS422 interface, etc. Software compatible with CH341, use the driver of CH341 directly. Support 5V and 3.3V power supply even 3V. CH340G/CH340T/CH340R chips need to work with a 12MHz clock signal supplied to the XI pin. Generally, the clock signal is generated by crystal oscillation with an inverter in CH340. The peripheral circuit needs to place a crystal of 12MHz between XI and XO and connect to a capacitor to ground separately. SOP-16 lead-free RoHS-compliant package.
