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, output and interrupt output. The USB device mode of CH375 is compatible with CH372, and CH375 incorporates all functions of CH372. For USB-DEVICE/SLAVE mode operation and specification, please refer to the CH372 specification. This data sheet only covers USB-HOST mode operation.
