MIKROE-3456 RTC 8 Click Mikroe MIKROE-3456 RTC 8 Click is a real-time clock module with extremely low power consumption. This allows it to be used with a single-button cell battery for an extended period. The RV-3028-C7 module is built on the RTC 8 click and can output time into the standard format and 32-bit UNIX format. Integrated, factory-calibrated XTAL operating at 32.768kHz 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 like an alarm function, countdown timer function, external event detection function with time stamp, and much more.
