低功耗IC卡接口

TDA8023是一款完整的高性价比、低功耗模拟接口，用于同步或异步智能卡。可以将它放置在卡片和微控制器之间，只需极少量的外部元件便可实现所有电源、保护和控制功能。 I²C总线控制型IC卡接口采用TSSOP28封装\n电源电压：2.7 V至6.5 V\n独立电源电压VDD(INTF)可用于微控制器的信号接口\n器件不工作时可提供关断输入，具有极低的功耗\n卡片激活时提供低功耗模式\nDC-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）\n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\n两条副卡I/O线，由I²C总线（C4和C8）控制\nVCC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;
