ICStation CH375B U Disk Read Write Module Supply SPI Host Interface 6MHz Useful I.Feature 1).CH375 CH375B is a USB bus general interface chip which supports the USB-HOST Mode and SB-DEVICE/SLAVE Mode.It has 8-bit data bus and control lines for reading, writing and chip selection and output interruption,which can be easily attached to the system bus of controllers such as MCU / DSP / MPU.In USB host mode, CH375B also provides serial communication, which can be connected to MCU / DSP / MPU, etc. via serial input, serial output, and interrupt output. 2). The USB host of CH375 supports common used USB device at full speed, the external microcontroller can use CH375 in accordance with the relevant USB protocol to communicate with USB device. It also has on-board firmware with Special communication protocol to deal with Mass-Storaged evice. The external microcontroller can read and write these common used USB storage device directly via the basic unit sectors. II.Application ?To read and write the U-Disk. ?To research the CH375B chip ?To research USB protocol research ?To learn the FAT16/32 file system ?TO use in all kinds of U-Disk III.Parameter IV.Mechanical drawing Unit: mm Function: ?Low-speed and full-speed USB-HOST interface, compatible withe USB V2.0, just needs crystal and capacitance as external devices. ?Low-speed and full-speed USB interface, compatible with the CH372, automatically switch Host Mode and Device Mode. ?Input and output buffer is 64 bytes, each host endpoint support 12 Mbps full speed USB devices and 1.5 Mbps low speed Equipment? ? Supports USB device control transfer, bulk transfer and interrupt transfer. ? Supply SPI host interface with 6MHz, supports SD card, MMC card and TF card which compatible with protocol. ? Detects USB device plug and unplug automatically and sends message to USB host. ? set protocol manager of USB control transfer in the inner to simplify common control transfer. ? Set up firmware of special communication protocol to do with Mass-storage. Supports Bulk-Only transfer protocol and USB storage device of SCSI, UFI, RBC and other equivalent storage device which accommodates the minimum set of command including USB Flash Drive, USB HD, USB flash memory and USB reader. ? Set file system manage firmware of FAT16, FAT32 and FAT12, support the capacity up to 32GB USB Flash Drive and SD Card. ? Supply file manage function: open, create or delete file, enumerate and search file, create the sub-catalog, and support the long file name. ? Supply file read/write function: read/write file in the much long sub-catalog take byte as unit or fan as unit. ? Supply disk manage function: initialize disk, query physical capacity, query spare space, physical sectors read/write. ? Supply 8-bit passive parallel interface with 2MB speed, support parallel data bus connect to MCU. ?Supply asynchronism serial interface up to 3Mbps speed, support serial interface connect to MCU, support automatically adjust communication baud-rate. ? Supply SPI device interface with 2MB/24MHz speed, support SPI serial bus connect to MCU. ? Source power is 5V or 3.3V, and low-power mode is supported. ? USB-DEVICE Mode is totally compatible with CH372 chip, USB-HOST Mode is basically compatible with CH375 chip. ?Adoption SOP-28 and SSOP20 lead-free package, compatible with RoHS, supplies diversion board from SOP28 to DIP28, the pins of SOP28 are compatible with CH375.
