Description  
Block Diagram  
The RV3029C2 is a Real-Time-Clock Module with embedded crystal. This  
RTC has an I2C Bus (2-wire Serial-Interface) and offers temperature  
compensated time. The STC (Smart Temperature Compensation) can be  
factory calibrated to achieve a very high time accuracy of ±6ppm from  
-40°C to +85°C (option A) and ± 8ppm from -40°C to +125°C (option C).  
Beside standard RTC functions, it includes a Backup-Battery Input with  
internal switchover function, a programmable trickle-charge circuitry, an  
integrated temperature sensor with digital output and offers 8 Bytes RAM  
and 2 Bytes EEPROM for customer application.  
The calendar function tracks year and leap-year flags. The clock tracks  
second, minute and hour in 24-hour format. Programmable alarm setting  
and universal timer functions increase flexibility.
