DESCRIPTION:

This miniature SMD ceramic package has been specially designed to

combine the 32.768 kHz crystal unit with the CMOS-based oscillator and

real-time-clock circuit.

The calendar function tracks year, month, date, and day-of-the-weekwith

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.

For pick-and-place equipment, the parts are available in 12 mm tape:

7" (178 mm) reel with 1 '000 parts

7" (178 mm) reel with 3'000 parts
