分子检测设备的原理与PCR仪类似，通过对基因的扩增，从而实现对各种人类或动物体病菌病毒的检测，国内某客户在做一个小型的分子检测设备时，需要用到USB接口与外部进行数据传输，因此需要一个USB转串口的转接芯片，给客户推荐了沁恒的CH340E。

CH340E主要具有以下特点：

1、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。

2、硬件全双工串口，内置收发缓冲区，支持通讯波特率50bps～2Mbps，支持常用的MODEM联络信号RTS、DTR、DCD、RI、DSR、CTS，

3、通过外加电平转换器件，提供RS232、RS485、RS422等接口，支持5V电源电压和3.3V电源电压，CH340E内置时钟，无需外部晶振。

典型应用电路如下：

综上所述，CH340E可以满足客户设计需求，应用于分子检测设备的设计。
