I²C RTC，带有涓流充电器

DS1340是一款实时时钟(RTC)/日历，与ST M41T00引脚兼容且功能相当，包括软件时钟校准。该器件还额外提供了VBACKUP引脚上的涓流充电功能、更低的计时电压和振荡器停止标志。寄存器映射的块访问与ST器件相同。涓流充电器和标志需要两个单独访问的附加寄存器。时钟/日历提供秒、分、时、星期、日期、月和年信息。内置电源检测电路可检测电源故障并自动切换到备用电源。该器件通过I²C双向总线进行串行编程。\n\n   • ST M41T00的增强型替代选择\n\n• 完全管理所有计时功能\n• RTC为秒、分、小时、星期、日期、月和年计数\n\n• 软件时钟校准\n\n• 振荡器停止标志\n\n\n\n\n• 低功耗运行可延长备用电池运行时间\n• 计时电压低至1.3V\n\n• 自动电源故障检测和开关电路\n\n• 涓流充电功能\n\n\n\n\n• 三种工作电压范围（1.8V、3V和3.3V）支持使用传统和现代电源总线的系统\n\n• 集成晶体的表面贴装封装(DS1340C)可节省额外空间并简化设计\n\n• 通过简单的串行端口与大多数微控制器进行接口\n• 快速(400kHz) I2C接口\n\n\n;
