Real Time Clock Module with SPI Bus DIMENSIONS Package: 100% leadfree, RoHS - compliant Ultra low power consumption 130nA Automotive qualified, according to AEC-Q200 Rev. C Xtal integrated solution. Frequency-Offset Trimming Register Miniature SMT ceramic package Very tight frequency tolerance SPI Bus Interface (SCL up to 8 MHz) Programmable Clock-output Low aging Time keeping mode down to 1.1 V Programmable alarm, timer and interrupt functions 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 ags. The clock function tracks minute and second in 24-hour format. Programmable alarm setting and universal timer functions increase 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 BLOCK DIAGRAM: O S C ILLA T O R 32 .768 k H z
