DESCRIPTION:
This very small SMD ceramic package has been specially designed to
combine the 32.768 kHz crystal unit with the CMOS-based oscillator
circuit. The calendar functions track year, month, date, and day with
built-in century and leap-year flags. The clock functions tracks hour,
minute, second, and hunderdth of second in 24- or 12-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 1'500 parts
10” (254 mm) reel with 3'500 parts
