DS2401+ Frequently Asked Questions (FAQs)

  • The maximum frequency of the 1-Wire bus is 16.3 kHz, but it can be overclocked to 28 kHz with some limitations.
  • To ensure reliable communication over long 1-Wire bus cables, use a cable with a characteristic impedance of 50 ohms, and add a 1 kohm pull-up resistor to the data line. Also, consider using a repeater or a buffer to boost the signal.
  • No, the DS2401+ is designed to operate with a 3.3V power supply. Using a 5V power supply may damage the device.
  • Implement a retry mechanism to handle errors, and use a timeout to detect and recover from errors. Also, consider using a CRC (Cyclic Redundancy Check) to detect data corruption.
  • Yes, the DS2401+ supports multiple masters on the same 1-Wire bus, but each master must have a unique ROM ID and must follow the 1-Wire bus protocol to avoid conflicts.
