Abstract
The utility model discloses a USB flash disk with double interfaces of a serial port and USB. The USB flash disk consists of a mechanical interface, a single-pole double-throw switching switch, a processor, a NAND Flash storage device, an electrically erasable programmable read-only memory (EEPROM) and a power chip. The USB flash disk has the function of a USB flash disk, comprises the double interfaces of the serial port and USB, flexible interface option is provided for a user, and convenience is provided for data storage of equipment with a serial port low-speed interface only and interaction storage of equipment with a high-speed USB interface.
Description
Technical field
The utility model relates to a kind of USB flash disk with serial ports and USB double nip, it can be used as USB flash disk and uses, have two kinds of interfaces of serial ports and USB, select for the user provides flexibly interface, and store alternately for the data storage of the equipment that only has the serial ports low-speed interface and with the equipment with hi-speed USB interface convenience is provided.
Background technology
At present, the USB interface USB flash disk is a kind of very popular mobile memory medium, and it provides easily having the storage of data mobile on the equipment of hi-speed USB interface, mutual function, along with the progress of Flash manufacturing technology, the capacity of USB flash disk is also advanced by leaps and bounds, and USB flash disk is day by day indispensable in daily.At present, also exist a large amount of equipment at industrial circle and adopt the low side processor, it does not have hi-speed USB interface, but a lot of equipment needs again a large amount of data storage and transmission.The utility model has well realized having the USB flash disk of hi-speed USB interface and two kinds of interfaces of industrial general serial ports, select for the user provides flexibly interface, and store alternately for the data storage of the equipment that only has the serial ports low-speed interface and with the equipment with hi-speed USB interface convenience is provided.
The utility model content
The utility model provides a kind of USB flash disk with serial ports and USB double nip for the user, has realized the ingenious combination of industrial low side processor mobile storage and main flow USB interface mobile storage.
The technical scheme that its technical matters that solves the utility model adopts is: be connected to simultaneously on the mechanical interface of USB flash disk by serial ports and the USB interface of single-pole double-throw (SPDT) change-over switch with processor.Its concrete technical scheme is as follows:
In the utility model, be connected to simultaneously on the mechanical interface of USB flash disk by serial ports and the USB interface of single-pole double-throw (SPDT) change-over switch with processor, the user can switch to serial ports pattern or USB interface pattern freely by this switch.
In the utility model, processor has serial ports, USB interface and parallel data grabbing card.
In the utility model, NAND Flash storer is directly connected on the processor by parallel data grabbing card, and NAND Falsh is as mobile memory medium, and processor directly is stored in user's data among the NAND Flash.
The beneficial effects of the utility model are, be integrated in flexibly serial ports and USB interface on the USB flash disk, select for the user provides flexibly interface, and store alternately for the data storage of the equipment that only has the serial ports low-speed interface and with the equipment with hi-speed USB interface convenience is provided.
Description of drawings
Fig. 1 is schematic diagram of the present utility model.
Embodiment
Below in conjunction with drawings and Examples the utility model is further specified.
