The is a Real Time Clock Module with I²C-bus. Designed to achieve an ultra-low power consumption of typically 130nA at VDD 3.0V in time-keeping mode. The calendar function tracks year, month, date and day-of-the-week with built-in century and leap-year flags. The clock function tracks minute and second in 24-hour format. Programmable alarm setting, dual timer functions and integrated switch-over circuitry to backup supply voltage increase flexibility.
