CH340C USB to Serial Chip SOP16- No External Crystal Required – Replace CH340G

Description

Introduction
CH340C is a USB bus convert chip and it can realize USB convert to serial interface,
In serial interface mode, CH340C supplies common MODEM liaison signal, used to enlarge
asynchronous serial interface of computer or upgrade the common serial device to USB bus directly. 

Yet another member of popular CH340 family of USB to serial converter chip. This particular variant of CH340C is designed with internal clock and does not require external crystal oscillator resulting in lesser BOM cost. Pin drop replacement for CH340G.
