Smart Card & SIM Card Interfaces | NCN8025
概览
NCN8025/NCN8025A 是一款紧凑且成本高效的单智能卡接口。它专用于 1.8 V / 3.0 V / 5.0 V 智能卡读/写应用。该卡 VCC 电源通过内置的极低漏和低噪声 LDO 提供。该器件完全兼容 ISO 7816-3、EMV 4.3、UICC 和相关标准，包括 NDS 和其他 STB 标准（Nagravision、Irdeto...）。它满足对机顶盒 (STB) 或 条件访问模块（CAM 和 CAS）进行条件访问的规定要求。此智能卡接口集成电路采用 QFN-24 封装 (NCN8025A)，提供了 STB 智能卡接口通常所需的所有行业标准功能。它还采用非常紧凑的封装 QFN-16 (NCN8025)，满足 CAM 和 SIM 应用所需的成本高效和空间节省要求。有关器件实施的详细信息，请参考应用注释 AND8003，该说明可根据要求提供（请联系当地销售办公室或销售代表）。
