The utility model is described further with reference to the accompanying drawings and detailed description.
Description of the drawings
Fig. 1 is the smart card architecture frame diagram of the utility model.
Fig. 2 is the smart card architecture figure of the utility model specific implementation.
Fig. 3 is the smart card SIM contact size of the utility model specific implementation and its positional distance mark schematic diagram.
Specific embodiment
As shown in Figure 1, the smart card architecture block diagram for the utility model.Wherein, which includes SD controllers 10, dodges
Chip 20, SIM units 30, SIM contact 40, SD contacts 50 and substrate 60 are deposited, the SIM contact 40 and SD contacts 50 are encapsulated in
The surface of the substrate 60.
In order to realize that telecommunication service is handled simultaneously with SD store transactions, SD controllers 10 and SIM units 30 are mutually independent
Internal structure.SIM units 30 have the function of processing telecommunication service, and the interface externally communicated is 7816 interfaces of ISO/IEC,
So SIM units 30 can be connected with the SIM contact 40 on substrate surface.SD controllers 10 have processing SD store transactions
Function, the interface externally communicated are SD interfaces, so, SD controllers 10 can be connected with the SD contacts 50 on substrate surface.
Flash chip 20 is the main medium of mass data storage, and the data stored carry out pipe by SD controllers 10
Reason, including data being written into flash chip, data are read out of flash chip, carrying out data format, right to flash chip
Junk data carries out the operation such as recycling in flash chip, so, flash chip 20 can be connected with SD controllers 10.
In order to meet the requirement of different user, product of the present invention can match different flash chips, including flash memory
The type of chip, memory capacity of flash chip etc. are combined into a variety of different configuration of products, as SLC 32GB flash memories particle,
MLC 64GB flash memory particles etc..
Wherein, SD controllers 10 are responsible for processing SD data store transactions with flash chip 20, and SIM units 30 are responsible for processing electricity
Communication service just to be relied on there is no data interaction or principal and subordinate and be closed since there is no connection relations, this two groups of working cells before them
System.When SD data store transactions and SIM telecommunication services occur simultaneously, two groups of working cells can be obtained from different interfaces please
It asks or data, and independently summed data is asked to be handled and responded these, the present invention is made not only from the appearance while to support
SIM and SD contacts, and functionally also realize and supported while standby with the SIM card use of Micro SD memory expansions.
As shown in Fig. 2, the smart card architecture figure for the utility model specific implementation.The smart card has SIM and SD simultaneously
Function, size appearance and eight SD contacts, i.e. P1, P2, P3, P4, P5, P6, P7, P8 have been with existing Micro SD cards
It is complete consistent, meet the Micro SD card specification standards of Micro SD associations publication.In order to support SIM card telecommunication service simultaneously,
On substrate, i.e., six SIM contacts, i.e. C1, C2, C3, C5, C7, C8, these SIM contacts are added on Micro SD cards body surface face
Definition meet ISO/IEC7816-2 international standards.Since Micro SD card surface residuals space is limited, and SIM telecommunications functions
It does not need to C4 and C8 contacts and participates in communication, so not increasing C4 and C8 contacts in case is embodied, if there is actual needs
It can be increased according to the contact position of terminal.Meanwhile in order to match the two-in-one card slots of Micro SD/SIM and its place terminal
Corresponding contacts position, the arrangement of SIM contact and its position will be different, to be adapted to more with Micro SD/SIM bis-
Unify the terminal of card slot.
As shown in figure 3, for the smart card SIM contact size of the utility model specific implementation and its positional distance mark signal
Figure.In case is embodied, the representative value in the position of SIM contact, the equal according to the form below of size is implemented.In Fig. 3 (one), SIM
The long side of contact is 2.00 millimeters, and narrow side is 1.70 millimeters.Horizontal distance between the two neighboring SIM contact center is
7.62 millimeters, vertical range is 2.54 millimeters.In Fig. 3 (two), the length of the SIM contact closest apart from substrate one side
The distance range on side and substrate one side is 1.3 millimeters, and the narrow side of SIM contact and substrate on one side at a right angle while distance range
It is 0.5 millimeter.In Fig. 3 (three), distance apart from while long side and substrate of the substrate on one side the closest SIM contact
Ranging from 2.2 millimeters, and it is 0.3 millimeter that while narrow side of SIM contact and substrate are at a right angle on one side, which s distance range,.But in reality
, may be there are some deviations in production or process, it should be in the range of minimum or maximum value.
Smart card while the utility model with SIM and SD is not limited to embodiment discussed above.Base
It should also be as being considered within the scope of protection of the utility model in the obvious transformation of the utility model enlightenment or replacement.With
On specific embodiment be used for disclosing the best implementation of the utility model so that those of ordinary skill in the art's energy
Enough reach the purpose of this utility model using the numerous embodiments of the utility model and a variety of alternatives.
