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.
