Abstract
The invention discloses a double-memory-card mobile phone. The double-memory-card mobile phone comprises a microprocessor controller, a main board, a first card reading device and a second card reading device, wherein the microprocessor controller, the first card reading device and the second card reading device are all arranged on the main board, and the first card reading device and the second card reading device are both connected with a microprocessor controller circuit. By means of the double-memory-card mobile phone, memory cards can be inserted into the first card reading device and the second card reading device respectively; after data connection between the memory cards and the card reading devices is achieved, data in the mobile phone can be stored through the two memory cards, and the storage ability of the mobile phone is effectively enhanced.
Description
Technical field
The present invention relates to electronic communication technology, relate in particular to a kind of mobile phone.
Background technology
Along with the fast development of electronic technology, mobile phone becomes the instrument of people's indispensability.Along with the enhancing of cell-phone function, more and more higher to the requirement of mobile phone storage capacity.The data such as document, voice data, video data, mobile phone application software, game, picture, photo all need mobile phone to have powerful storage capacity.Mobile phone of the prior art, only arrange a T-FLASH reader device, therefore can only insert a T-FLASH storage card,, though can reach the purpose of extension storage ability, can not reach user's user demand.
Summary of the invention
The purpose of this invention is to provide a kind of mobile phone supporting two SD cards, the storage capacity of flexible extended mobile phone.
Mobile phone supporting two SD cards provided by the present invention, comprise microprocessor controller, mainboard, the first reader device and the second reader device, described microprocessor controller, described the first reader device and described the second reader device all are arranged on mainboard, described the first reader device be connected the second reader device and all with described microprocessor controller circuit, be connected.
Mobile phone supporting two SD cards provided by the present invention, can insert storage card respectively in described the first reader device and described the second reader device, after realizing storage card and the data of described reader device being connected, can realize utilizing two storage cards to store data in mobile phone, effectively expand the storage capacity of mobile phone.
Description of drawings
The electrical block diagram of the mobile phone supporting two SD cards that Fig. 1 provides for the embodiment of the present invention.
Embodiment
For the purpose, technical scheme and the advantage that make the embodiment of the present invention clearer, below in conjunction with the accompanying drawing in the embodiment of the present invention, technical scheme in the embodiment of the present invention is clearly and completely described, obviously, described embodiment is the present invention's part embodiment, rather than whole embodiment.Based on the embodiment in the present invention, those of ordinary skills, not making under the creative work prerequisite the every other embodiment that obtains, belong to the scope of protection of the invention.
As shown in Figure 1, the present embodiment provides a kind of mobile phone supporting two SD cards, comprise microprocessor controller, mainboard, the first reader device and the second reader device, described microprocessor controller, described the first reader device and described the second reader device all are arranged on mainboard, described the first reader device be connected the second reader device and all with described microprocessor controller circuit, be connected.It will be understood by those skilled in the art that described microprocessor controller is used for controlling described the first reader device and the second reader device pair realizes that with it storage card of data communication carries out read-write operation.Can insert storage card respectively in described the first reader device and described the second reader device, after realizing storage card and the data of described reader device being connected, can realize utilizing two storage cards to store data in mobile phone, effectively expand the storage capacity of mobile phone.
Further, described microprocessor controller is provided with the CPI interface, and described the first reader device is connected with described CPI interface circuit.
Further, described microprocessor controller also is provided with the GPIO interface, and described the second reader device is connected with described GPIO interface circuit.
Further, described GPIO interface comprises a GPIO interface, the 2nd GPIO interface, the 3rd GPIO interface and the 4th GPIO interface, and a described GPIO interface, the 2nd GPIO interface, the 3rd GPIO interface and the 4th GPIO interface all are connected with described the second reader device.The CPI interface that it will be understood by those skilled in the art that microprocessor controller has 4 signal pins, is respectively: data input pin (SDI), data output pin (SDO), clock pin (SCK) and chip select pin (CS).The present embodiment utilizes above-mentioned first to fourth four signal pins of the above-mentioned CPI interfaces of totally four GPIO interfaces simulation, realizes controlling with the GPIO interface purpose of the second reader device.Like this, can solve the microprocessor controller that only is provided with a CPI interface and can't connect simultaneously the problem of two reader devices, utilize the GPIO interface as the supplementing of CPI interface, not improve the cost that mobile phone is made.
Further, the level on a GPIO interface, the 2nd GPIO interface, the 3rd GPIO interface and the 4th GPIO interface is 2.8V.
Further, described the first reader device is the T-FLASH reader device; Described the second reader device is also the T-FLASH reader device.So just realized that mobile phone can use two T-FLASH storage cards to carry out the function of data storage simultaneously.
It should be noted that finally: above embodiment only, in order to technical scheme of the present invention to be described, is not intended to limit; Although with reference to previous embodiment, the present invention is had been described in detail, those of ordinary skill in the art is to be understood that: it still can be modified to the technical scheme that aforementioned each embodiment puts down in writing, and perhaps part technical characterictic wherein is equal to replacement; And these modifications or replacement do not make the essence of appropriate technical solution break away from the spirit and scope of various embodiments of the present invention technical scheme.
