DS1302SN-16/T&R Frequently Asked Questions (FAQs)

• What is the recommended crystal oscillator frequency for the DS1302SN-16/T&R?
  The recommended crystal oscillator frequency for the DS1302SN-16/T&R is 32.768 kHz, which is a standard frequency for real-time clocks.
• How does the DS1302SN-16/T&R handle battery backup during power failures?
  The DS1302SN-16/T&R has a built-in battery backup switchover circuit that automatically switches to the backup battery when the main power supply fails, ensuring that the clock continues to run and retain its data.
• What is the maximum operating temperature range for the DS1302SN-16/T&R?
  The maximum operating temperature range for the DS1302SN-16/T&R is -40°C to +85°C, making it suitable for a wide range of industrial and commercial applications.
• Can the DS1302SN-16/T&R be used in a 5V system?
  Yes, the DS1302SN-16/T&R can be used in a 5V system, but it requires an external voltage regulator to regulate the voltage to 3V, which is the maximum operating voltage for the device.
• How does the DS1302SN-16/T&R handle leap years?
  The DS1302SN-16/T&R automatically adjusts for leap years, so the user does not need to manually adjust the clock for leap years.
