Working Principles

The RX-8803LC:UC PURE SN utilizes an internal oscillator to generate a 32.768 kHz clock signal. This signal is used as a reference for timekeeping and synchronization. The module communicates with external microcontrollers through the I2C interface, allowing for easy integration into various electronic systems.

During normal operation, the module draws power from the main supply voltage (VCC). In the event of a power loss, a backup battery maintains the clock and calendar information. The module automatically switches between the main supply and battery backup as needed.
