RV-8803-C7 Real Time Clock Module with I2C-Bus DIMENSIONS Package: Recommended Solder Pad: 100% leadfree, RoHS - compliant Extremely Accurate RTC Module with embedded Quartz Crystal. Ultra Low Power consumption I2C Interface Automotive qualified, according to AEC-Q200 Rev. C Temperature Compensation: Temperature 0°C to +50°C -40°C to +85°C Time Deviation ± 0.13 s/day ± 1.5 ppm ± 0.26 s/day ± 3.0 ppm Lowest current consumption & smallest temperature compensated RTC Module! All dimensions in mm typical DESCRIPTION: The RV-8803-C7 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 and results to 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 24hour format, year and leap -year flags. Beside standard RTC function 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 and offers the lowest current consumption among all temperature compensated RTC modules.
