DS1371U+ Frequently Asked Questions (FAQs)

  • The recommended power-up sequence is to apply VCC first, followed by VBAT. This ensures that the internal registers are properly initialized and the device operates correctly.
  • When the battery is dead or removed, the DS1371U+ will reset and lose its clock and calendar information. To handle this, you can use the VBAT pin to detect the battery presence and take appropriate action, such as resetting the device or using a backup power source.
  • The internal oscillator of the DS1371U+ has an accuracy of ±10 ppm over the operating temperature range of -40°C to +85°C. This means that the clock frequency can deviate by up to 10 parts per million from the nominal frequency.
  • Yes, the DS1371U+ can be used as a standalone clock generator. It can generate a 32.768 kHz clock signal, which can be used to drive other devices or circuits. However, note that the device also has a built-in real-time clock (RTC) function, so you may need to disable the RTC function if you only want to use it as a clock generator.
  • The DS1371U+ can be interfaced with a microcontroller using a 3-wire serial interface (SCL, SDA, and RST). The microcontroller can read and write data to the DS1371U+ using the I2C protocol. You can use the device's address pins (A0, A1, and A2) to select the device address and communicate with it.
