CH375 Description
The DataSheet of CH375 (the first) 1 USB Bus Interface Chip CH375 English DataSheet Version: 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 munication in USB-HOST...
