Abstract
The utility model provides a novel radio-frequency SD card comprising a power switch module, a SD controller, a storage module, a safety module, a radio frequency module, and an antenna. The two ends of the antenna are connected with the radio frequency module. The radio frequency module communicates with the safety module by a S2C signal. The power output Vcc of the radio frequency module is connected with the power input pin of the safety module. The SD controller is connected with the safety module through GPIO ports. The SD controller is connected with the storage module through FLASH interfaces. The power output Vcc of the power switch module is connected with the power input pin of the SD controller and the power input pin of the storage module. The novel radio-frequency SD card has low power consumption.
Description
Technical field
The utility model relates to the mobile communication technology field, is specifically related to a kind of mobile phone New-type radio-frequency SD card capable of reducing energy consumption again that neither relies on.
Background technology
Two kinds of radio frequency Micro-SD cards are arranged in the market, and the first is antenna integrated, the fully integrated SD card of radio-frequency module, SD controller, storage chip, safety chip, and it two is SD cards of integrated RF module, SD controller, storage chip, safety chip.The antenna of the second SD card is integrated on mobile phone, therefore mobile phone is had dependence, carries out more difficult; The first SD card, integrated active radio frequency chip on card, the power supply of the power supply of its radio frequency chip, SD controller chip, the power supply of safety chip all from the VDD contact of SD card, as long as mobile phone powers up the SD interface, block interior security module, radio-frequency module, the SD controller all is powered, if the SD interface is in idle condition, namely the user to the SD card without operation, this moment the SD controller, safety chip is powered on is unnecessary, is the waste energy.
The utility model content
In view of this, be necessary the problem mentioned for background technology, a kind of mobile phone New-type radio-frequency SD card capable of reducing energy consumption again that neither relies on is provided.
The purpose of this utility model is achieved through the following technical solutions:
a kind of New-type radio-frequency SD card, it comprises power switching module, the SD controller, memory module, security module, radio-frequency module and antenna, the two ends of described antenna are connected with described radio-frequency module, the S2C of UNICOM signal between described radio-frequency module and security module, and the power supply of described radio-frequency module output Vcc is connected on the power supply input pin of described security module, described SD controller is connected by the GPIO mouth with described security module, described SD controller is connected by the FLASH interface with described storer, the power supply output Vcc of described power switching module is connected on the power supply input pin of described SD controller and described memory module, described New-type radio-frequency SD card also comprises VDD contact, CLK contact, GND contact, CMD contact, DAT0 contact, DAT1 contact, DAT2 contact and DAT3 contact, described VDD contact and described radio-frequency module and power switching module connection, described CLK contact is connected with described power switching module, described contact GND is connected with the earth terminal of described power switching module, SD controller, memory module, security module, radio-frequency module, and described CMD contact, DAT0 contact, DAT1 contact, DAT2 contact and DAT3 contact all are connected to described SD controller module.
Compared with prior art, the utility model possesses following advantage:
Principle of the present utility model is: realize energy control by the induction output signal of active radio frequency module and the clock signal of SD card interface clock line.concrete, the power supply of radio-frequency module directly comes from the VDD contact of SD interface, the power supply of security module directly comes from the power supply output Pin of radio-frequency module, the power supply of SD controller and the power supply of memory module are controlled by the clock signal on the SD interface, clock signal is as the switching signal of power switching module, when the user conducts interviews to the SD controller, to send clock signal, the power switching module conducting, the user without when operation, without clock signal, power switching module is closed, therefore the user during without operation, only radio-frequency module and power switching module are in holding state, its radio-frequency module and power switching module are very low in the energy consumption of holding state.
