DESCRIPTION:
Xtal integrated solution
Miniature SMT ceramic package
Ultra low power consumption
Very tight frequency tolerance
I2C Bus Interface (400 kHz) *
Programmable Clock-output
Low aging
Time keeping mode down to 1.2 V
Programmable alarm, timer and
interrupt functions
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 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
10” (254 mm) reel with 2'500 parts
13” (330 mm) reel with 5'000 parts
