带涓流充电的时钟芯片

DS1302涓流充电计时芯片包含实时时钟/日历和31字节静态RAM。它通过简单的串行接口与微处理器通信。实时时钟/日历提供秒、分、时、星期、日期、月和年信息。对于少于31天的月份，月底的日期会自动调整，包括针对闰年的更正。时钟以24小时制或带AM/PM指示器的12小时制运行。\n\n 通过使用同步串行通信，简化了DS1302与微处理器的接口。只需三根线即可与时钟/RAM通信：CE、I/O（数据线）和SCLK（串行时钟）。在与时钟/RAM之间进行数据传输时，可以一次1个字节，也可以在一次突发中包含多达31个字节。DS1302工作时的功耗非常低，并以低于1µW的功耗保留数据和时钟信息。\ • 完全管理所有计时功能\n• 实时时钟可为秒、分、小时、日期、月、星期和年计数，闰年补偿有效期至2100年\n\n• 31 x 8电池供电通用RAM\n\n\n\n\n• 通过简单的串行端口与大多数微控制器进行接口\n• 简单的3线接口\n\n• TTL兼容(VCC = 5V)\n\n• 用于读取或写入时钟或RAM数据的单字节或多字节（突发模式）数据传输\n\n\n\n\n• 低功耗运行可延长备用电池运行时间\n• 2.0V至5.5V全面运行\n\n• 2.0V时电流消耗小于300nA\n\n\n\n\n• 8引脚DIP和8引脚SO封装充分减少了所需空间\n\n• 可选工业温度范围：-40°;
