Real Time Clock Module with l2C Bus MICRO CRYSTAL SWITZERLAND 100% leadfree, RoHS - compliant Automotive qualified, according to Xtal integrated solution Miniature SMT ceramic package Ultra low power consumption Very tight frequency tolerance Programmable Clock-output Time keeping mode down to 1.2 V Programmable alarm, timer and interrupt functions 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 BLOCK DIAGRAM: Voltage Detector Month / Century Minutes Alarm Hour Alarm Weekday Alarm CLKOUT frequency Timer Control * The l2C Bus is a trademark of Philips Electronics N.
