Positive power input port, requires an external 0.1uF power decoupling capacitance Public ground, ground connection for USB Attachment of VCC input external power while 3.3V;connects of 0.01uF decoupling capacitance outside while 5V Input of crystal oscillator, attachment of crystal and crystal osci.

The DataSheet of CH375 (the first) 1 USB Bus Interface Chip CH375 English DataSheet Version: 3E http://wch.cn 1. 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
