RV2123C2 clock equivalent, real time clock.
Ultra low power consumption Compliant with 4-wire SPI-Bus Time keeping mode down to 1.1 V Frequency-offset trimming register Programmable alarm, timer and inte.
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.
