Product Description

The RV-8803-C7 is a high accuracy, low power real-time-clock module with embedded 32.768 kHz Crystal. High accuracy and high stability is achieved by a factory calibrated, temperature compensated DTCXO giving time-accuracy of ±3.0ppm across the temperature range from -40°C to +85°C, and ±7.0ppm over extended operating temperature range from +85 to +105°C.

Standard Clock & Calendar function tracks second, minute, and hour in 24-hour format, and provides year and leap-year flags. Beside standard RTC functions such as Timer & Alarm, the RV-8803-C7 also includes an 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.

In order to align ourselves with industry-standard nomenclature the name of this product has been revised from RV8803C7 to RV-8803-C7. There have been no changes to form, fit or function of the component. You can find more information in our product change notice PCN19032005321 here.
