带有闹钟的串行实时时钟

DS1305串行、带闹钟的实时时钟是全二进制编码的十进制(BCD)日历钟，可以通过简单的串行接口访问。该时钟/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，包括闰年的修正。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。此外，96字节NV RAM可以用来存储数据。当振荡器使能时，只要任意一个电源有效，DS1305将保持时间和日期。独立的接口逻辑电源引脚(VCCIF)使DS1305可以将SDO与/PF引脚驱动至与接口逻辑兼容的电平。便于在混合供电系统中与3V逻辑接口。\n\n DS1305提供双电源输入和一个电池输入引脚。 • 实时时钟(RTC)计算秒、分、时、星期、日、月、年信息，具有有效至2100年的闰年补偿\n• 为数据存储提供96字节电池备份的NV RAM\n• 两个可编程日历闹钟，可设定在特定的秒、分、时和星期\n• 串行接口支持Motorola SPI (串行外设接口)串行数据口或标准3线接口\n• 突发模式可连续读/写时钟/RAM\n• 双电源引脚分别用于主电和备电\n• 可选的涓流充电输出用于备用电源\n• 2.0V至5.5V供电\n• 工业级温度范围：-40°C至+85°C\n• 采用节省空间的20引脚TSSOP封装;
