Description

一种智能SD卡
技术领域
本实用新型涉及通信及数据存储卡,具体是指一种智能SD卡。
背景技术
随着射频识别技术的发展和移动通信终端的日益普及,在手机中嵌入智能SD卡,即带移动支付功能的micro SD card,使人们能够利用手机中的智能卡处理购物消费、小额支付和考勤等日常事务,已经成为移动通信业界的一个新的研究和发展方向。目前,智能SD卡安装在手机内,其由智能芯片(实现射频通信功能的电路)和现有普通SD卡合为一体成为智能SD卡。
由于各个厂家对智能SD卡的设计不规范,没有形成统一标准,导致设计出来的智能SD卡smart chip和memory单一,生产工艺难度大;特别是因为flash和智能芯片因供货周期、价格高低、加工工艺导致不能批量生产而影响供货。
实用新型内容
本实用新型需解决的问题是提供一种工作可靠、智能化控制、兼容性强的智能SD卡。
为了实现上述目的,本实用新型设计出一种智能SD卡,它包括电源管理芯片LD0,所述的电源管理芯片LD0与智能SD卡的主控MCU和智能芯片联接。
所述的电源管理芯片LD0的输入端VIN与电容C2和卡接口的FVDD33端连接,电源管理芯片LD0的3脚CE端与主控MCU的LD0-EN端连接,电源管理芯片LD0的输出端VOUT与电从C3和智能芯片的SVDD33端连接。
本实用智能SD卡可以实现多种flash和智能芯片组合成的智能SD卡,实现灵活组合生产;通过这样的标准化设计,优化产品的可制作性。
附图说明:
图1是本实用新型智能SD卡基板框图;
图2是本实用新型智能SD卡载板框图。
具体实施方式
为了便于本领域技术人员的理解,下面将结合具体实施例及附图对本实用新型的结构原理作进一步的详细描述。
如图1、2所示,一种智能SD卡,它包括有基板和载板,所述的基板上设有主控MCU、FLASH和载板内部接口,所述的载板上设有载板外部接口,基板1通过载板内部接口与载板上的载板外部接口连接。
智能SD卡在现有的面积下很难扩展memory存储容量,采用flash堆叠设计来满足大容量智能SD卡。
本实用新型智能SD卡采用多种智能芯片和多种flash兼容设计,满足智能SD卡的多种组合设计。
本实用新型智能SD卡采用标准化接口,通过载板实现和智能芯片通信功能,基板内部接口分别定义为ISO7816(VCC、RST、CLK、IO、GND)、SWP(SWP)、ANT(ANTA、ANTB)天线接口,基板和载板相连,组合成带移动支付的智能SD卡。载板接口分别定义为ISO7816(VCC、RST、CLK、IO、GND)、SWP(SWP)、ANT(ANTA、ANTB)天线接口,载板和基板相连,组合成带移动支付的智能SD卡。
本实用新型智能SD卡中ISO7816接口和智能卡连接通过智能SD卡SD协议间接实现远程支付功能;swp接口和NFC手机连接实现现场支付功能;ANT接口和专用手机连接实现现场支付功能。
上述内容,仅为本实用新型的较佳实施例,并非用于限制本实用新型的实施方案,本领域技术人员根据本实用新型的构思,所作出的适当变通或修改,都应在本实用新型的保护范围之内。
