Product Brief
 
CH375 is a universal interface chip of USB bus, which supports USB-Host mode and usb-device / slave device mode. At the local end, CH375 has 8-bit data bus, read-write, chip select control line and interrupt output, which can be easily connected to the system bus of MCU / DSP / MCU / MPU and other controllers. In the USB host mode, CH375 also provides a serial communication mode, which is connected with MCU / DSP / MCU / MPU through serial input, serial output and interrupt output. The USB device mode of CH375 is fully compatible with h372 chip, and CH375 includes all functions of CH372. The USB host mode of CH375 supports the commonly used USB full speed device, and the external MCU can communicate with the USB device through CH375 according to the corresponding USB protocol. CH375 also has the firmware of special communication protocol for mass storage device. The external MCU can read and write the USB storage device (including USB hard disk / USB flash disk / USB flash disk) in the basic unit of sector.
