1. Introduction
CH376 is used as file manage control chip, used to MCU system read/write file in USB Flash Drive or
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 file system
manage firmware in the inner. It supports common USB storage devices (contains USB Flash Drive/USB
hard disk/USB Flash memory/USB read card) and SD cards (contain SD card with standard capacity and
HC-SD card with high capacity, MMC card and TF card compatible with protocol).
CH376 supports three communication interfaces: 8-bit parallel, SPI interface or asynchronism serial
interface. DSP/MCU/MPU etc. controller via the any interface of them to control CH376 chip, storage and
get file in USB Flash Drive or SD card, or communication with computer.
The USB-DEVICE Mode of CH376 is totally compatible with CH372, the USB-HOST Mode of
CH375 is basically compatible with CH375.
