DS1302 是DALLAS 公司推出的涓流充电时钟芯片,内含有一个实时时钟/日历和31 字节静态RAM,通过简单的串行接口与单片机进行通信实时时钟/日历电路.提供秒分时日日期.月年的信息,每月的天数和闰年的天数可自动调整时钟操作可通过AM/PM 指示决定采用24 或12 小时格式.DS1302 与单片机之间能简单地采用同步串行的方式进行通信.-DALLAS DS1302 is a trickle charge introduced by the company clock chip, containing a real-time clock/calendar and 31 bytes of static RAM, via a simple serial interface to communicate with the MCU real-time clock/calendar circuit. To provide second time-on date. Month years of information, the number of days per month and leap year automatically adjust the number of days the clock operation by AM/PM directives decided to use 24 or 12 hour format. DS1302 and the microcontroller can simply between the way synchronous serial communication.
