C 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 All dimensions in mm typical DESCRIPTION: 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-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 7” (178 mm) reel with 3'000 parts BLOCK DIAGRAM: * The I2C Bus is a trademark of Philips Electronics N.V.
