CH342K是一个USB总线的转接芯片，实现USB转两个异步串口。
每个串口都支持高速全双工，支持奇偶校验，提供了常用的MODEM联络信号，用于为计算机扩展异步串口，或者将普通的串口设备或者MCU直接升级到USB总线。
全速USB设备接口，兼容USB V2.0。
仿真标准串口，用于升级原串口外围设备，或者通过USB增加额外串口。
计算机端Windows操作系统下的串口应用程序完全兼容，无需修改。
支持免安装的操作系统内置CDC类驱动程序或者多功能高速率的VCP厂商驱动程序。
双硬件全双工串口，内置独立的收发缓冲区，支持通讯波特率50bps～3Mbps。
串口支持5、6、7或者8个数据位，支持奇校验、偶校验、空白、标志以及无校验。
支持常用的MODEM联络信号RTS、DTR、DCD、RI、DSR、CTS。
支持CTS和RTS硬件自动流控。
支持半双工，提供正在发送状态支持RS485切换。
通过外加电平转换器件，支持RS232接口。
USB端支持5V电源电压和3.3V电源电压。
串口I/O独立供电，支持5V、3.3V和2.5V甚至1.8V电源电压。
内置上电复位，内置时钟，无需外部晶振。
CH342F内置EEPROM，可配置芯片VID、PID、最大电流值、厂商和产品信息字符串等参数。
芯片内置Unique ID(USB SeriaNumber)。
提供 QFN24 和 ESSOP10 无铅封装，兼容 RoHS。
