Timekeeping Functions: Tracks seconds, minutes, hours, day, date, month, and year, with leap-year compensation valid up to 2100. Non-Volatile Memory: Includes 56 bytes of battery-backed, non-volatile SRAM for data storage, preserving data during power loss. I2C Interface: Communicates via a two-wire I2C interface, simplifying integration with microcontrollers like Arduino. Low Power Consumption: Operates with minimal power usage, making it suitable for battery-powered applications. Square Wave Output: Provides a programmable square wave output signal, which can be used for timing applications. Automatic Power-Fail Detection: Features circuitry that detects power failures and automatically switches to the backup supply, ensuring continuous timekeeping
