RV-2123-C2 is a CMOS real-time clock/calendar module optimized for ultra low power consumption. Data is transferred serially via a Serial Peripheral Interface (SPI-bus) with a maximum data rate of 6.25Mbits/s, the built-in word address register is incremented automatically after each written or read data byte. Beyond standard RTC-functions like year, month, day, weekday, hours, minutes, seconds information, the RV-2123-C2 offers Alarm and Timer-Interrupt function, programmable Clock-Output and Voltage-Low-Detector. A programmable Offset-Register allows fine tuning of the clock to improve time-accuracy @ 25°C, for ageing adjustment or to compensate the frequency-drift over the temperature of the 32.768 kHz “Tuning-Fork” crystals.
