This very small SMD ceramic package has been specially designed to
combine the 32.768kHz crystal unit with the CMOS based oscillator and
real-time clock circuit.
The calendar function tracks year, month, date and day of the week with
built-in century and leap-year flags. The clock function tracks minutes
and seconds in 24-hour format. Programmable alarm setting and
universal timer functions increase flexibility.
