Description
This RTC IC has been specially designed to achieve an ultra-low power
consumption of typically 130nA @ VDD 3.0V in time-keeping mode.
The very small SMT ceramic-package combines the 32.768 kHz crystal unit
with the CMOS-based oscillator and real-time-clock circuitry. 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 and universal timer
functions increase flexibility.
