Technical field

The utility model relates to a kind of silicon disk card, and the particularly a kind of USB of utilization conversion equipment constitutes the MS silicon disk card with two interfaces in conjunction with the MS silicon disk card.

Background technology

MS memory card, full name are " Memory Stick ", are a kind of by erasable formula storage body and a minisize memory card or the silicon disk card that control wafer is formed of being coated in the housing.The novel memory card standard of SONY Corporation in issue in 2000 adopted at its mechanism size and electrical equipment interface.This MS memory card has advantages such as volume is little, in light weight, access speed is fast, capacity is big, and in conjunction with SONY group this in resource and market share such as every consumer electronic device, portable electron device and information-based household electrical appliances, applied rapidly, and replaced the Storage Media of traditional floppy disk and CD and become one of novel Storage Media of numerical data.But, the MS memory card aims at the MS card interface that self uses because only adopting, though SONY can be at the various consumer electronic devices of himself producing, the MS memory card exploitation special interface of portable electron device and information-based household electrical appliances, so that the numerical information that is in the MS memory card is deposited in access, if the consumer is applied in this MS memory card the external system that generally is not equipped with MS memory card interface, such as the consumer for often need be the time with desk side computer system or mobile computer system, then just can't take into account the needs of dual-use, thereby can't carry out the function of data transmission or exchange.So generally speaking, the consumer is except that system transmissions function itself that utilize above-mentioned information household appliances to have, silicon disk card) or adapter often need purchase MS card card reader with controller separately (claims again:, can between personal computer system and MS memory card, carry out operations such as data transmission and exchange, so that cause inconvenience and puzzlement in the use.Yet the system of this desktop computer and notebook computer all is set to expand transport interface and formulates unified standard USB interface specification, is a kind of computer system host or mancarried device, so that expand the extended interface of various peripheral device.Since the USB interface have transfer rate height, safety easy, hot-swappable, support advantage such as multiple variety classes peripheral device, make all desktop PC systems and all built-in this kind extended interface of mobile computer system at present, its peripheral device also comprises: input media (keyboard, mouse, rocking bar), storage device (hard disk, floppy disk, CD, silicon dish), output unit (digital horn), communication device (USB radio network device, USB connecting line).

Therefore invention artificially thoroughly addresses the above problem or defective, eliminate desk-top and or the mobile computer system to the extra cost that demand produced and the operational complicacy of extra attachment device, the inventor is through arduous research and development, make above-mentioned MS memory card can pass through a conversion equipment cheaply, the function that can directly connect the most universal USB extended interface of personal computer system, the MS memory card can be changed by the most easy device, thereby with minimum cost, the mode of operation of most convenient is at personal computer system and various consumer electronic device, the storage of numerical information is provided between mancarried device and the information household appliances, transmission, function with exchange.

Summary of the invention

Fundamental purpose of the present utility model is only to have the MS memory card at the exclusive interface of MS originally, can pass through appropriate device automatic checkout system interface, and automatically switch to correct system interface and support the Storage Media at the USB interface that personal computer is the most universal simultaneously, remember and become two interface MS, significantly reduce system cost (demand of getting rid of extra coupling arrangement) thereby have, characteristics such as more convenient operation (install, more convenient operation simple).

For realizing above-mentioned purpose, the utility model provides a kind of pair of interface MS silicon disk card, it comprises silicon disk card and the conversion equipment thereof of establishing microcontroller in one, wherein silicon disk card has the MS interface of standard, in order to be connected with conversion equipment or external device (ED), the throw-over gear cording has a slot and a USB interface, this slot is in order to bearing MS silicon disk card, the USB interface is then in order to be connected with external system, its characteristic is: the microcontroller cording of this MS silicon disk card has automatic detection, judge whether external device (ED) supports MS transport interface or USB transport interface, make its except that utilize self possess MS interface access data, also can reach the access of external data on the erasable storage body of MS memory card by the USB conversion equipment.

Embodiment

See also shown in Figure 1, the of the present utility model pair of interface MS silicon disk card and conversion equipment thereof, it comprises that mainly a silicon disk card 1 and a conversion equipment 2 constitute; Wherein silicon disk card 1 has a main body, the appropriate location of main body is provided with first transport interface 11 (being the MS transport interface) of a MS memory card standard, and body interior is provided with a circuit board 12 (PCB), this circuit board is provided with one and has a microcontroller 13 and a plurality of erasable formula storage body 14, be weldingly fixed on this circuit board 12 with surface mounted technology, wherein this microcontroller 13 has one first bus interface circuit 131 (being MS bus-bar interface) at least, data transmission temporary slow-action zone 132 and power-switching circuit 133, certainly more include control access interface and procedure code storing memory body etc. and constitute, and above-mentionedly will not give unnecessary details at this for the design concept of all unit well known to those skilled in the art and structure.

Conversion equipment 2 comprises a slot and second transport interface 21 (being the USB transport interface) with silicon disk card interface at least, this slot provides the grafting of above-mentioned silicon disk card 1, and second transport interface 21 that can utilize this conversion equipment 2 and computer system and or outside system with USB extended interface be connected.

The novel main characteristic of this use is: the microcontroller 13 of this silicon disk card 1 is to be provided with one second bus interface circuit 134, and control and commutation circuit 135 are detected in an interface, in order to automatic detection and automatically switch first bus interface circuit 131 or second bus interface circuit 134, because this has automatic detection for controller 13, switch and whether support MS interface or USB interface, when the microcontroller 13 of MS silicon disk card 1 detects one of them of first bus interface circuit 131 or second bus interface circuit 134, be circuit and the electronic component in the automatic switch-over circuit plate, data transmission action with first transport interface of supporting MS card 1 or second transport interface, make external data be able to store access on the body 14 in erasable formula, thus, a silicon disk card that has MS and the two interface transmission of USB effect concurrently forms.
