Real-time clock module RV-2123-C2

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. User programmable offset value. Oscillator stop detection. Provides year, month, weekday, date, hours, minutes and seconds. Timer and Alarm functions. Automotive qualification according to AEC-Q200 available. The RV-2123-C2 RTC module is ideal for IoT Wearables, Portables Health Care Metering Industrial Automotive
