低电流SPI/3线RTC

DS1343/DS1344低电流实时时钟(RTC)是一款计时器件，具有超低待机电流，能够在备份电源供电时保持更长的使用寿命。器件支持高ESR晶体，从而扩展了器件的晶体选择范围。时钟/日历部分提供秒、分、时、星期、日期、月和年信息。对于少于31天的月份，可在月末自动调整日期，包括闰年修正。时钟部分工作于24小时制式或带/AM/PM指示的12小时制式。\n\n 可通过SPI™或3线接口串行传输地址和数据。器件具有两个可编程定时闹钟，每个闹钟可对秒、分、小时、星期组合设置产生中断。如果不需要闹钟功能，则在一个或多个字段中将插入一些“无关”项。可以设置定时闹钟触发两个不同的中断输出，或者将其 • 250nA (典型值)低计时电流\n• 允许使用ESR高达100kΩ的晶体 \n• 器件支持6pF或12.5pF晶体\n• RTC计算秒、分、时、星期、日期、月和年，闰年修正有效至2099年\n• 电源失效和开关电路\n• 三种工作电压\n• 1.8V ±5%\n• 3.0V ±10%\n• 3.3V ±10%\n\n\n• 涓流充电功能\n• 电源电压低至1.15V (典型值)时仍可维持计时\n• 支持Motorola SPI模式1和3，或标准3线接口\n• 以突发模式在时钟/RAM中进行连续读/写操作 \n• 96字节电池备份NV RAM，用于数据存储\n• 两;
