DS1307 is a low-power all-BCD code clock calendar real-time clock chip with 56 bytes of nonvolatile RAM. The address and data are transmitted through a two-wire bidirectional serial bus. The chip can provide information such as seconds, minutes and hours, and the number of days in each month can be automatically adjusted. The AM/PM flag determines whether the clock works in 24-hour or 12-hour mode. The chip has a built-in power sensing circuit, which has the functions of power failure detection and battery switchin.
