特征

  • I²C总线控制型IC卡接口采用TSSOP28封装
  • 电源电压：2.7 V至6.5 V
  • 独立电源电压VDD(INTF)可用于微控制器的信号接口
  • 器件不工作时可提供关断输入，具有极低的功耗
  • 卡片激活时提供低功耗模式
  • DC-DC转换器用来生成VCC（根据电源电压和卡片电压自动选择容性倍频器、三倍器、电感或跟随器）
  • 一条受专门保护的半双工双向缓冲I/O线，限流为+-15 mA，最大频率为1 MHz
  • 两条副卡I/O线，由I²C总线（C4和C8）控制
  • VCC调节：5 V、3 V或1.8 V +- 8%，ICC< 55 mA，电流尖峰为40 nAs（最高20 MHz），上升和下降时间受控，滤波过载检测约为80 mA，限流约为120 mA
  • 针对所有卡片接触的热保护和短路保护
  • 自动激活与取消激活序列：发生短路、卡片移走、过热、VDD或VDD(DCDC)下降等事件时，可通过软件或硬件初始化
  • 卡片端具有增强静电放电(ESD)保护功能(> 6 kV)
  • 20 MHz时钟输入
  • 卡片的时钟生成频率高达10 MHz（CLKIN 1/2/4/5分频），具有同步频率变化；高电平或低电平停止，或以1 MHz在卡片低功耗模式下自由运行；针脚CLK (C3)具有限流功能
  • RST信号(C2)限流为20 mA，由异步卡上的嵌入式可编程CLK脉冲计数器控制，或由同步卡上的寄存器控制
  • 兼容ISO 7816-3、GSM 11.11和EMV 2000（支付系统）
  • 电源电压监控器用于上电尖峰消除和关断时的紧急取消激活；阈值内部固定或通过外部电阻桥进行设置；脉冲宽度内部固定或通过外部电容进行设置
  • 内置10 ms去抖系统的卡片存在性输入
  • 一个中断信号INT

Target Applications
