The recommended crystal oscillator frequency for the DS1312S-2 is 32.768 kHz, which is a standard frequency for real-time clocks.
The DS1312S-2 has an internal switchover circuit that automatically switches to the battery supply during power failure, ensuring continuous operation of the real-time clock.
The typical current consumption of the DS1312S-2 is around 1.5 μA, making it suitable for battery-powered applications.
Yes, the DS1312S-2 can be used in a system with multiple power domains, as it has a separate VCC pin for the real-time clock and a separate VBAT pin for the battery supply.
The internal oscillator of the DS1312S-2 has an accuracy of ±10 ppm over the operating temperature range, which is sufficient for most real-time clock applications.
