Block Diagram

This sub-miniature SMD ceramic package has been specially designed to

combine the 32.768kHz crystal unit with a 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.
