C Bus
All dimensions in mm typical
DESCRIPTION:
This very small 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-week with
built-in century and leap-year fl ags. The clock function tracks minute and
second in 24-hour format. Programmable alarm setting and universal
timer functions increase fl exibility.
For pick-and-place equipment, the parts are available in 12 mm tape:
7” (178 mm) reel with 1'000 parts
13” (330 mm) reel with 5'000 parts
