{"product_id":"ds1302-real-time-clock-rtc-module","title":"DS1302 Real Time Clock RTC Module","description":"\u003cp\u003eDS1302 Real Time Clock RTC Module is a trickle charge clock chip, containing a real-time clock\/calendar and 31 bytes of static RAM, communicating through serial interface simple and single-chip microcomputer. The real-time clock\/calendar circuit provides seconds, hours, days, weeks, months, years of information, a number of days in the month and leap year can automatically adjust. The clock operation instructions through the AM\/PM decided to use a 24 or 12-hour format.\u003c\/p\u003e\u003cp\u003eBetween DS1302 and single-chip microcomputer can simply use synchronous serial communication method, only three lines:\u003c\/p\u003e\u003col\u003e\n\u003cli\u003e\u003cp\u003eRST\u003c\/p\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cp\u003eI\/O reset the data line\u003c\/p\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cp\u003eSCLK serial clock.\u003c\/p\u003e\u003c\/li\u003e\n\u003c\/ol\u003e\u003cp\u003eClock \/RAM read\/write data to a byte character set or as many as 31-byte communication.
