DS1374U-33+ 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.
  • When the battery is dead or removed, the DS1374U-33+ will reset and lose its clock data. To handle this, you can use an external capacitor to maintain the VBAT voltage for a short period, allowing the device to retain its clock data.
  • The maximum clock accuracy deviation over temperature is ±2 ppm from 0°C to 40°C, and ±3 ppm from -40°C to 85°C.
  • Yes, the DS1374U-33+ can be used as an RTC in a battery-backed mode. The device can switch to battery power when the main power supply (VCC) is removed, allowing the RTC to continue running.
  • The DS1374U-33+ 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 DS1374U-33+ using I2C protocol.
