DS2431+ datasheet by Maxim Integrated Products

DS2431+ Frequently Asked Questions (FAQs)

• What is the maximum number of DS2431+ devices that can be connected to a single 1-Wire bus?
  Up to 256 devices can be connected to a single 1-Wire bus, but the maximum number of devices that can be practically connected depends on the bus capacitance, wire length, and noise environment.
• How do I ensure reliable communication with the DS2431+ over long distances?
  To ensure reliable communication over long distances, use a twisted pair or shielded cable, keep the bus capacitance low, and use a 1-Wire bus repeater or buffer if necessary.
• What is the purpose of the VPP pin on the DS2431+?
  The VPP pin is used to program the EPROM memory of the DS2431+. It should be connected to a programming voltage (VPP) of 12V to 15V during programming, and to VCC or left floating during normal operation.
• How do I prevent data corruption during power-up or power-down of the DS2431+?
  To prevent data corruption, ensure that the power supply to the DS2431+ is stable and monotonic during power-up and power-down. Avoid sudden power interruptions or voltage drops.
• Can I use the DS2431+ in a multi-drop configuration?
  Yes, the DS2431+ can be used in a multi-drop configuration, where multiple devices are connected to a single 1-Wire bus. Each device must have a unique ROM code to ensure proper addressing.
