Introduction CH375 is a USB bus universal interface chip, supports USB-HOST Mode and USB-DEVICE/SLAVE Mode.

There are 8-bit data bus and read, write, chip select control wire and interrupt output in CH375.It is convenient to link CH375 to control system bus of MCU/DSP/MPU.CH375 also provides serial communication in USB-HOST mode.

It connects with DSP/MCU/MPU through serial input,

CH375 Features

* Full-speed USB-HOST interface, conforms to USB Specification Version 2.0, only needs crystal and capacitance external.

* Full-speed USB device interface, compatible with CH372, supports exchanging USB-HOST mode and USB-DEVICE/SLAVE mode dynamically.

* Input and output buffers of host e
