DS1338Z

I²C RTC，带有56字节NV RAM; \n• 实时时钟(RTC)记录秒、分、时、星期、日、月、年信息，具有有效至2100年的闰年补偿 \n• 内置晶振(DS1338C)，采用表面贴封装 \n• 为数据存储提供56字节电池备份的NV RAM \n• I²C串行接口 \n• 可编程方波输出 \n• 自动电源失效检测与转换电路 \n• -40°C至+85°C工作温度范围;

DS1338串行实时时钟(RTC)是低功耗、全二进制编码的十进制(BCD)时钟/日历，外加56字节NV SRAM。地址与数据通过I²C总线串行传送。时钟/日历可以提供秒、分、时、日、月、年信息。对于少于31天的月份，到每月的最后一天会自动进行调节，包括闰年修正。该时钟可以通过AM/PM指示器工作在24小时模式或12小时模式。DS1338具有一个内部电源感应电路，可以检测到电源失效，并自动转换到备用电源。
