看门狗时钟，带有NV RAM控制器

DS1558为完备的、2000年兼容(Y2KC)的、实时时钟/日历(RTC)，具有RTC报警、看门狗定时器、上电复位、电池监控以及NV SRAM控制器。用户访问DS1558中所有寄存器都通过完整数据资料中的图1所示的字节宽度接口来实现。RTC寄存器包含24小时制BCD格式的世纪、年、月、日、星期、时、分、秒数据。对于每月天数及闰年的修正均自动完成。\n DS1558的RTC寄存器占用SRAM地址空间，不断地检测A0-A18地址总线。当访问任何高16位地址空间，DS1558将禁用SRAM的/CER和/OER信号，将读和写重新定向至DS1558内的RTC寄存器。DS1558所用SRAM地址空间可达 \n• 集成了实时时钟(RTC)、电源失效控制电路以及NV RAM控制器 \n• 访问时钟寄存器的方式与静态RAM相同；这些寄存器占用16个顶部RAM地址 \n• 世纪寄存器 \n• 采用小型钮扣锂电池及低漏电流的SRAM，在工作电源断电条件下，时间和数据可维持10年以上 \n• 精确的上电复位 \n• 可编程的看门狗定时器和RTC报警 \n• BCD编码的世纪、年、月、日、星期、时、分、秒，同时具有自动闰年补偿至2100年 \n• 电池电压高低指示标志 \n• 电源失效写保护允许±10% VCC电源容差;
