A file dump storage device based on MCU was introduced.As the control core of system,the C8051F040 MCU connected two CH375 U-disk modules,one LCD screen and the keyboard module to realize communicating between two U-disks directly and independent of PC,which made the U-disks not susceptible to viruses.The C8051F040 MCU realized the communication by USB protocol and USB equipment,which supports top speed(12Mb/s) equipment and low speed(1.5Mb/s).The operator can use the program given by the CH375 to read the data from the flash disk and realize the communication between MCU and the flash disk.The device has merits of low lost,low power loss,simple to operation etc,it has widely application prospect.
