CH376S

CH376 is a file management control chip for reading and writing files in a USB flash drive or SD card.

CH376 supports USB device mode and USB host mode, and has built-in basic firmware of USB communication protocol, built-in firmware for processing the dedicated communication protocol of Mass-Storage mass storage device, built-in communication interface firmware of SD card, built-in FAT16, FAT32 and FAT12 file system management firmware, support common USB storage devices (including U disk / USB hard disk / USB flash disk / USB card reader) and SD card (including standard capacity SD card and high capacity HC-SD card and protocol compatible MMC card and TF card).

CH376 supports three communication interfaces: 8-bit parallel port, SPI interface or asynchronous serial port. The controller such as MCU/DSP/MPU can control CH376 chip through any of the above communication interfaces, access files in U disk or SD card or Communicating with a computer. The USB device mode of the CH376 is fully compatible with the CH372 chip. The USB host mode of the CH376 is basically compatible with the CH375 chip.
