The RTC 8 Click Board™ is a real-time clock module that has an extremely low power consumption, allowing it to be used with a single button cell battery, for an extended period of time. The RV-3028-C7 module built on the RTC 8 Click Board™ is able to output the time in the standard format, as well as in the 32-bit UNIX format. Integrated, factory calibrated crystal operating at 32.768 kHz ensures a very low time deviation.
The compensation and offset data are stored within the internal non-volatile memory. There is also a possibility to password-protect the configuration parameters. An advanced interrupt feature allows many different uses such as alarm function, countdown timer function, external event detection function with time stamp and much more.
