Embodiment
Further specify the technical solution of the utility model below in conjunction with embodiment and accompanying drawing.
Embodiment as shown in Figure 1, have two interfaces on the flash memories adapter 100 among this embodiment, first interface 102 and second interface 104, first interface 102 is the slave computers that are used for being connected to embedded system, in this embodiment, it has 24 * 2 pin, promptly is two inboard row's apertures.On connected next bit computer, also have 24 * 2 interface, this interface links to each other with first interface 102, and pin is corresponding one by one, will specify below about connected mode.Second interface 104 is two row's apertures in the outside, it also has the interface of 24 * 2 pins, second interface 104 is connected to the flash recordable device, also have the corresponding interface that 24 * 2 pins are arranged accordingly on the cd-rom recorder and link to each other, when needs burning or change flash chip internal processes content, finish corresponding internal processes burning or modification with second interface 104.As shown in Figure 1, on this adapter 100, first interface 102 and second interface 104 are arranged according to following form, first interface 102 is two inboard rounds, spacing between them is 100mil, second interface 104 is two rounds 104 in the outside, and the spacing between them is 300mil (mil is a kind of long measure, and 1000mil is an inch).Interface with 24 * 2 pins is a communication interface commonly used in the prior art, and simultaneously, the pitch of holes of 100mil and 300mil is also used always., realize respectively when corresponding interface on slave computer and the cd-rom recorder is connected at first interface 102 and second interface 104 by the corresponding metal pin.Also has flash chip interface 106 on this flash memories adapter 100, as shown in Figure 2.The leg identical with flash memories chip pin number arranged (for example on the flash memories chip interface 106, according to general standard, have 48 pins), the flash memories chips welding on flash memories chip interface 106, the corresponding leg of each pin.Because the pin number of most flash memories all is identical (comprising different manufacturers, different model, the flash memories chip of different capabilities), therefore above-mentioned flash chip interface 106 goes for most flash chips.
Each interface on the flash memories adapter 100 all be certainly mutually together with, just take embodiment shown in Figure 1 to illustrate, Fig. 3 is its detail circuits figure, as shown in Figure 3, three interfaces: the pin between first interface 102, second interface 104 and the flash memories chip interface 106 is connected to each other correspondingly, so its effect just is equivalent to flash chip directly is inserted on the mainboard after being connected to first interface 102 on the next bit computer.
In conjunction with Fig. 2 this adapter 100 connected mode of its interface in use is described more below.Said that above the interface of this 24 * 2 pins of Shi Yonging is the communication interface of using always herein.When realizing the interconnection of this kind communication interface again, totally 48 of metal needles are configured to 24 * 2 form equally.But the spacing at metal needle two ends can be different, for example, spacing between the hole of first interface 102 of this adapter 100 is 100mil, and spacing is 300mil between the hole of second interface 104, like this, just (this is meant the pin spacing of an end that is used to connect for 100mil to be used to connect spacings of metal needle 202 its two rows pins of first interface 102, the i.e. part of representing with solid line among the figure, other local spacing can be random, the i.e. part that dots among the figure), the spacing that is used to connect two row's pins of second interface 104 just is 300mil.The corresponding pin of each root metal needle uses 48 metal needles just can make two 24 * 2 structure realize that pin links to each other one to one.Flash chip 200 among Fig. 2 is welded on the flash memories chip interface 106.Fig. 2 its ways of connecting of just schematically drawing, because this kind interface is widely used in this area, the utility model also is a kind of application for this kind interface herein, so the description of those skilled in the art on reference also afterwards can realize technical scheme of the present invention in conjunction with the accompanying drawings.
Because the structure of this adapter is very simple, cost is very low, can be equipped with a this adapter for each piece flash chip, flash chip is welded on this card once, when needs use flash memories, just be connected in the corresponding interface on the computer motherboard, when needs carry out burning to flash memories, just be connected to cd-rom recorder by second interface by its first interface.No matter in which kind of is used, do not relate to direct plug, therefore can not touch the pin on the flash chip again, the security of operation will be improved widely for the flash memories chip.
The foregoing description provides to being familiar with the person in the art and realizes or use of the present utility model; those skilled in the art can be under the situation that does not break away from invention thought of the present utility model; the foregoing description is made various modifications or variation; thereby protection domain of the present utility model do not limit by the foregoing description, and should be the maximum magnitude that meets the inventive features that claims mention.
