AW39103，可高效实现电平转换，保障通讯稳定。AW39103产品特性AWINIC主控Host端供电电压范围：1.08V~1.98VSIM卡端供电电压范围：1.65V~3.6V支持25MHz时钟频率内部集成EMI滤波器内部集成必要的上拉电阻和下拉电阻，无需额外的外部电阻SIM卡端具有高于IEC61000-4-2最高等级的系统级ESD能力：接触放电＞±8kV，空气放电＞±15kV符合所有ETSI、IMT-2000 和 ISO-7816-3接口要求支持主控与SIM卡之间Clock、Data、Reset信号的自动电平转换封装：QFN 1.8mmx1.4mm-10L、FOWLP 1.06mmx1.06mm-9B图2  AW39103典型应用图1产品特点一符合ETSI、IMT-2000标准及ISO7816-3规范，可确保SIM卡的正常启用与禁用操作。AW39103集成三路电平转换器，可对SIM卡的RST、CLK 及IO信号进行电平转换，实现SIM卡端口（1.8V/3V）与主芯片端口（1.2V/1.8V）的正常通讯。产品遵循 ISO-7816-3 标准的关机时序要求：当EN引脚置低时，先关闭 RST_SIM 通路启动关机流程，随后CLK_SIM 和IO_SIM通路由内部下拉电阻拉低，整个关机时序可在10μs内完成，既能确保SIM卡正确禁用以降低功耗，也能在热插拔场景中避免数据误写与损坏。图3AW39103关断时序2产品特点二SIM卡端具有强健的ESD防护能力，可省去外部ESD器件，简化设计流程。AW39103的SIM卡端具备强劲ESD防护能力，可满足IEC 61000-4-2系统级ESD最高等级要求。传统设计中，工程师通常需额外增加或预留ESD防护器件以应对ESD 事件；而采用AW39103后，因其SIM卡侧已集成高等级系统级ESD防护，可直接省去外部ESD器件，简化设计流程。图4
