To ensure accuracy, use a high-quality crystal oscillator, maintain a stable power supply, and avoid exposing the device to extreme temperatures or electromagnetic interference.
Power up the VCC pin first, followed by the VBAT pin. This ensures that the internal registers are properly initialized.
Use a supervisory circuit to detect VBAT removal or a dead battery, and implement a power-fail detect circuit to reset the device and prevent data corruption.
Yes, but you'll need to adjust the internal clock divider settings accordingly. Consult the datasheet for guidance on calculating the divider values.
Use the device's low-power modes, disable unnecessary peripherals, and optimize the oscillator frequency to minimize power consumption.
