Description:
The “CH376S USB read/write module” was designed based on an onboard CH376S chip. This onboard chip performs most of the functions of the module. We need to just send some commands from the Arduino to the module and the CH376S chip will perform the rest. Meanwhile, It communicates with the module in three different ways: Parallel communication, SPI communication, and Serial (UART) communication.
CH376 functions as a file management control chip. This is used to MCU system read/write a file in USB Flash Drive or SD card. It supports USB-Device Mode and USB-HOST Mode. Set the basic firmware of USB communication protocol in the inner.
It also set firmware of special communication protocol to cope with Mass-Storage devices, communication interface firmware of SD card, FAT16, FAT32, and FAT12 filing system manage firmware within the inner. CH376 is capable of supporting three communication interfaces: 8-bit parallel, SPI interface, or asynchronous serial interface. DSP/MCU/MPU etc. controller connected via any interface of them to regulate CH376 chip, storage and acquire enter USB Flash Drive or SD card, or communication with the computer.
CH375 is designed as a USB bus interface chip that supports USB – the host and USB – device/slave equipment the way. USB host mode, CH375 also provides serial communication via serial input, serial output, and interrupt output monolithic/DSP/MCU/MPU connected. The two cm x 8 cm connector helps for the straightforward mounting with the MCU. Moreover, this chip consists of an Onboard 3.3 V LDO 1117, which provides 800 mA of current. It operates at a 5 V power supply powered from the target board.
