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.

  • Low power consumption: 130 nA @ 3 V.
  • Wide operating voltage range: 1.1 V to 5.5 V.
  • Time accuracy: ±20 ppm @ 25°C..
  • User programmable offset value.
  • Oscillator stop detection.
  • Provides year, month, weekday, date, hours, minutes and seconds.
  • Timer and Alarm functions.
  • Clock output frequencies: 32.768 kHz to 1 Hz.
  • SPI-bus interface: 4-wire, 8 MHz.
  • Automotive qualification according to AEC-Q200 available.
