The recommended operating voltage range is 1.6V to 5.5V, as specified in the datasheet.
The POR circuitry is internal and does not require any external components. It ensures the device resets properly during power-up.
The VBAT pin is used to connect a battery or a capacitor to store data in the RTC (Real-Time Clock) during power-down or battery-backup mode.
The operating temperature range is -40°C to 85°C. However, it's recommended to consult the datasheet for specific temperature-related characteristics and derating.
The S-24CM01CI-J8T1U4 uses an I2C interface, which is a standard serial communication protocol. You can use the I2C bus to communicate with the device from a microcontroller.
