The RV-2123-C2-TA-QC-020 is a real-time Clock Module with SPI bus interface. This RTC IC has been specially designed to achieve an ultra-low power consumption of typically 130nA at VDD 3V in time-keeping mode. The very small SMT ceramic-package combines the 32.768kHz 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 and universal timer functions increase flexibility.
