CH376S Disk Read Write Description

CH376 is common a USB bus interface chip, with 8 bit data bus and reading , writing and chip select
lines and interrupt output , can easily attached to the system bus of the single chip microcomputer
/DSP/MCU/MPU controller. In the USB host mode , CH376 also provides a serial communication
mode, through the serial input, serial output and interrupt output connected with the MCU
/DSP/MCU/MPU.
The “CH376S/CH375 USB read/write module” has a CH376S/CH375 chip onboard which does most
of the hard work for you. All you have to do is send the module some commands from the Arduino
and the CH376S/CH375 chip will do the rest. You can communicate with the module in three different

ways:
Communication
SPI and Serial (UART) .
CH376 is used as file manage control chip, used to MCU system read/write file in USB Flash Driver
SD card.
CH376 supports USB-Device Mode and USB-HOST Mode. Set the basic firmware of USB
communication protocol in the inner. It is also set firmware of special communication protocol to deal
with Mass-Storage devices, communication interface firmware of SD card, FAT16, FAT32 and FAT12
