RAMified Watchdog Timekeeper

FEATURES 128 kbytes of user NV RAM Integrated NV SRAM, real-time clock, crystal, power-fail control circuit and lithium energy source Totally nonvolatile with over 10 years of operation in the absence of power Watchdog timer restarts an out-of-control processor Alarm function schedu

RAMified看门狗计时器

DS1486为非易失静态RAM，具有完备的实时时钟(RTC)、闹钟、看门狗定时器以及间隔定时器，所有存储单元均可按照单字节宽度格式访问。DS1486内含一块锂电池以及一个石英晶振，无需任何外部电路。以与字节宽度的静态RAM同样读写方式，可以读或写保存在128K、8位内存的数据和时间保持寄存器。时间保持寄存器位于存储器的前14个字节，通过智能控制电路维持RAMified计时器内的数据，智能控制电路可以检测VCC的状态，在VCC超出容差时提供存储器写保护。在没有VCC供电时，锂电池最少可保存数据和时钟十年。日历信息包括百分之一秒、秒、分、时、星期、日、月、年，而对少于31天的月份，月终日期可自动调 \n• 128k字节用户NV RAM \n• 集成了NV SRAM、实时时钟、晶振、电源失效控制电路及锂电池 \n• 无电源供电时，可保持10年以上的非易失性 \n• 看门狗定时器可以重新启动一个失控处理器 \n• 闹钟功能可用于确定实时激活时间，如系统唤醒 \n• 可编程的中断和方波输出 \n• 所有寄存器可通过地址和数据总线分别寻址 \n• 掉电模式下中断信号保持有效;
