Real-Time Clock (RTC) chips are specialized integrated circuits designed to keep accurate time and date. They continue to run on a backup battery when the main power is off, ensuring persistent timekeeping. RTC chips are essential in various applications requiring time stamps or scheduled operations, such as in data loggers, computers, and alarm systems. They typically communicate with microcontrollers via I2C or SPI interfaces and are prized for their accuracy, low power consumption, and compact form factor.
