DS1232+ datasheet by Maxim Integrated Products

DS1232+ Frequently Asked Questions (FAQs)

• What is the maximum operating temperature range for the DS1232+?
  The DS1232+ can operate from -40°C to +85°C, but the accuracy of the real-time clock (RTC) may degrade at extreme temperatures.
• How does the DS1232+ handle battery backup during power failures?
  The DS1232+ has a built-in battery switch that automatically switches to the backup battery during power failures, ensuring that the RTC and SRAM data are preserved.
• What is the typical current consumption of the DS1232+?
  The typical current consumption of the DS1232+ is around 1.5mA during normal operation, but it can be reduced to around 10µA in battery-backed mode.
• Can the DS1232+ be used in a system with a 3.3V power supply?
  Yes, the DS1232+ can operate from a 3.3V power supply, but the input voltage range is 4.5V to 5.5V, so a voltage regulator may be required.
• How accurate is the real-time clock (RTC) in the DS1232+?
  The RTC in the DS1232+ has an accuracy of ±2 minutes per year at 25°C, but this can be affected by temperature, voltage, and other factors.
