DS1308U-33+T Frequently Asked Questions (FAQs)

  • A simple RC circuit with a 1kΩ resistor and a 10uF capacitor is recommended to ensure a clean power-on reset. This circuit should be connected between VCC and RST.
  • When the battery is removed and reinserted, the DS1308U-33+T will retain its clock data. However, it's recommended to reinitialize the clock and set the time after battery reinsertion to ensure accuracy.
  • The DS1308U-33+T has a maximum clock accuracy deviation of ±2 minutes per year over the operating temperature range of -40°C to +85°C.
  • Yes, the DS1308U-33+T can operate with a supply voltage as low as 2.0V, but it's recommended to use a 3.0V to 5.5V supply voltage for optimal performance.
  • The DS1308U-33+T uses a 3-wire serial interface (SCL, SDA, and RST) to communicate with a microcontroller. The microcontroller can use I2C or SPI protocols to read and write data to the DS1308U-33+T.
