DS1302, a trickle charge clock chip rolled out by DALLAS, is inclusive of a real-time clock\/calendar and 31 bytes of static RAM. It communicates with the microcontroller through the serial interface. The real-time clock\/calendar circuit provides information about seconds, minutes, hours, days, weeks, months, and years.
