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.
