CH375 module, 51 literacy U disk, USB communication
USB interface in the electronic products for very large share, SCM and USB interface communication is at present the most popular microcomputer application direction, this module USES one of CH375 for main control chip, CH375 is a USB (universal interface chip, support USB HOST mode and USB HOST- DEVICE/SLAVE equipment way. In the end, the local CH375 has 8 bits of data bus and reading, writing, and interrupt output control of choose, and we can easily hang received SCM/DSP/MCU/MPU, the system controller on the bus. In the USB host mode, CH375 also provides serial communication mode, through serial input, output and interrupt output and serial single/DSP/MCU/MPU or connection.
CH375 USB device way and the CH372 chip is fully compatible with CH375 contains CH372, all the functions. CH375 USB host ways to support the commonly used at full speed, external USB chip equipment can through the CH375 in accordance with the corresponding USB protocol and USB device communications. CH375 also built-in processing Mass Storage-a Mass Storage device special communication protocols of the firmware, external microcontroller can directly to the sector as the basic unit, speaking, reading and writing of commonly used USB Storage device (including USB hard drive/USB flash disk/U plate).
Had used for embedded system/SCM reading and writing U disk, ShanPan, flash disk, USB, USB mobile hard card reader, etc.
With related standard USB had support may have to transfer protocol based on-all kinds of U disk/flash disk/external hard drive.
Support the file system FAT12 and took FAT16 and FAT32.
-vice operation function: new files, delete, reading and writing data, open the closed documents, etc.
-vice SPI interface, support level 3.3 V
Had single chip solutions, this module need only a main control chip plus a small amount of capacitor and resistor, no matter the cost or module size has a great advantage.
Had this module can be according to special requirements
This module can be widely used in the USB interface equipment development, U disk storage control, data collection, category.
