Description

Block Diagram

The RV8803C7 is an high accuracy, ultra low power Real-Time-Clock

module with embedded 32.768 kHz Crystal. High accuracy, high stability is

achieved by factory calibrated, temperature compensated DTCXO giving

time-accuracy of ± 3.0 ppm accross the temperature range from -40°C to

+85°C. Standard Clock & Calendar function tracks second, minute, hour in

24-hour format, year and leap-year flags. Beside standard RTC functions

like Timer & Alarm, it includes integrated Temperature Sensor, Time

Stamp Event Input and User RAM and offers I2C-bus (2-wire Interface).

RV-8803-C7 is the smallest sized and consumes the lowest current of all

temperature compensated RTC modules.
