Description
Technical field
The invention relates to a kind of little storage card that repeats to write, particularly relevant for a kind of little storage card that repeats to write that can generally be used for different size memory card system interface.
Background technology
Because the suitable tool marketable value of future development of mini memory card, be to do one's utmost with each manufacturer own specification that expands all separately, expect that self-ordained memory card specifications is the storage card main flow in future.But this makes that also the storage card that expands out at present is not only respectively objective mutually on mechanism size, all have nothing in common with each other in electric interfaces, instruction set, Data Transport Protocol and control model, cause the specification of storage card itself and the system interface of support all to present the phenomenon that the bull carriage can't be unified, not only the consumer is caused puzzlement at a loss as to what to do, the degree of difficulty when also increasing information household appliances, digital electronic device and the exploitation of computing machine periphery manufacturer.
And for solving the above problems, the dealer releases a kind of switching device of supporting multiple storage card, its characteristic is that the specification of various storage cards, size and circuit are effectively integrated on single All-in-One read-write slot, and is connected transmission in order to data with the computer system end by single transmission interface such as USB, IEEE1394, PCMCIA, CF interface; But this device does not have memory function, only in the usefulness of the switching data transmission that storage card is provided, and can't directly be used in as on the devices such as digital camera, PDA or IA.
Therefore, if a kind of storage card of integrating interface specification, host-host protocol and the circuit etc. of multiple existing storage card can be arranged, and make it not need to reach and computer system end and each device binding application by the switching device of costliness, then can overcome because of various memory card specifications differ, and need expensive switching device connect computing machine puzzlement that the consumer is caused.
Summary of the invention
In view of this, the little storage card of a kind of general-using type that the present invention proposes, be for the inventor for addressing the above problem and reach on other different efficacies purpose, constantly after research and the test, can design the invention of great significance that can benefit the popular convenience on information is transferred of consumption at it eventually.
A fundamental purpose of the present invention is to hope the little storage card of this general-using type outside the system interface of itself formulating can be used, and also can support existing memory card system interface at present, as system interfaces such as SD and MS series.
Another object of the present invention is to hope this little storage card can support to be at present the USB system interface of standard perimeter interface.
For reaching above-mentioned purpose and effect, the little storage card of general-using type that the present invention proposes possesses one and shares transmission interface, can make between the memory card system interface of different size and the little storage card to carry out the transmission of signal by this shared transmission interface.The formulation that wherein should share transmission interface is to serve as to formulate the storage card on basis with the USB specification, and it is provided with the USB interface pin, in addition at least one data transmission pin of dosage.
The little storage card of this general-using type is except that reformulating on transmission interface, and its internal circuit is also done to change and improvement.Wherein, have one can repeat write store, it is characterized in that in the internal configurations of this little storage card:
Utilize the D+ and the D-interface pins of USB interface, several initializing signals that transmission is transmitted by the memory card system interface, and by electrically connecting the interface detecting/commutation circuit of sharing transmission interface, the potential change of those initializing signals of Auto-Sensing, judge the existing memory card system kind of interface of little storage card whereby, and the transmission route of switching signal according to this, microcontroller can be detected according to interface/the detecting result of commutation circuit and switch to and support the corresponding mode of operation of memory card system interface, and handle signal from different transmission routes according to mode of operation.
