DS1211+ datasheet by Maxim Integrated Products

DS1211+ Frequently Asked Questions (FAQs)

• What is the maximum number of devices that can be connected to the 1-Wire bus?
  The DS1211+ can support up to 256 devices on the 1-Wire bus, but the actual number of devices that can be connected depends on the specific application and the bus loading.
• How does the DS1211+ handle power-on reset and power-fail reset?
  The DS1211+ has a built-in power-on reset (POR) circuit that resets the device when the power supply voltage falls below a certain threshold. It also has a power-fail reset (PFR) circuit that resets the device when the power supply voltage falls below the minimum operating voltage.
• What is the maximum data transfer rate of the DS1211+?
  The DS1211+ has a maximum data transfer rate of 16.3 kbps, which is the standard data rate for 1-Wire devices.
• Can the DS1211+ be used in a multi-master configuration?
  Yes, the DS1211+ can be used in a multi-master configuration, where multiple masters can control the 1-Wire bus and communicate with multiple slaves.
• How does the DS1211+ handle bus contention and collisions?
  The DS1211+ uses a non-destructive bit-arbitration scheme to handle bus contention and collisions. When two or more devices try to transmit data at the same time, the device with the highest priority bit wins the arbitration and continues to transmit data.
