Product information
 
USB interface in the current electronic products accounted for a very large share of the microcontroller with USB interface communication direction of one of the most popular microcomputer application master chip module using the CH375, CH375 is a USB bus interface chip to support USB-The hOST and USB-DEVICE/SLAVE equipment the way. Locally, CH375 with 8-bit data bus and read, write, chip select control lines and interrupt output can be easily attached to the system bus of the microcontroller/DSP/MCU/MPU controller. USB host mode, CH375 also provides serial communication via serial input, serial output, and interrupt output monolithic/DSP/MCU/MPU connected.
 
CH375 USB device mode is fully compatible with CH372, CH375 contains all the features of the CH372. Common CH375 USB host mode support USB full-speed device, external microcontroller can through the the CH375 in accordance with the USB protocol and USB device communication. CH375 firmware also built a dedicated protocol processing Mass-Storage mass storage devices, external microcontroller can be directly used as the basic unit of reading and writing in sectors USB storage devices (including USB hard disk/USB flash drive/U disk).
