DESCRIPTION:
This RTC IC has been specially designed to achieve an ultra-low power
consumption of typically 130nA @ VDD 3.0V in time-keeping mode.
The very small SMT ceramic-package combines the 32.768 kHz crystal
unit with the CMOS-based oscillator and real-time-clock circuitry.
The calendar function tracks year, month, date, and day-of-the-week
with built-in century and leap-year flags. The clock function tracks minute
and second in 24-hour format. Programmable alarm setting, dual timer
functions and integrated switch-over circuitry to backup supply voltage
increase flexibility.
For pick-and-place equipment, the parts are available in 12 mm tape:
7” (178 mm) reel with 1'000 or 3'000 parts
13” (330 mm) reel with 10'000 parts
