CH375 是一个USB总线的通用接口芯片，支持USB-HOST主机方式和USB-device/SLAVE设备方式。在本地端，CH375具有8位数据总线和读、写、片选控制线以及中断输出，可以方便地挂接到单片机/DSP/MCU/MPU等控制器的系统总线上。在USB主机方式下CH375还提供了串行通讯方式，通过串行输入、串行输出和中断输出与单片机/DSP/MCU/MPU 等相连接。 CH375 的USB 设备方式与CH372 芯片完全兼容，CH375 包含了CH372 的全部功能。本手册中没有提供CH375 在USB 设备方式下的说明，相关资料可以参考CH372 手册。 CH375的USB 主机方式支持常用的USB 全速设备，外部单片机可以通过CH375 按照相应的USB 协议与USB 设备通讯。CH375 还内置了处理Mass-Storage 海量存储设备的专用通讯协议的固件，外部单片机可以直接以扇区为基本单位读写常用的USB 存储设备（包括USB 硬盘/USB 闪存盘/U 盘）。

Universal Serial Bus (USB) is a communications architecture that gives a personal computer (PC) the ability to interconnect a variety of devices using a simple four- wire cable. The USB is actually a two-wire serial communication link that runs at either 1.5 or 12 megabits per second (mbs). USB protocols can configure devices at startup or when they are plugged in at run time. These devices are broken into various device classes. Each device class defines the common behavior and protocols for devices that serve similar functions. Some examples of USB device classes are shown in the following table
