The DS1721S can support up to 256 devices on the 1-Wire bus, but it's recommended to limit it to 100 devices for reliable operation.
To ensure reliable communication, use a pull-up resistor between the 1-Wire bus and VCC, and keep the bus capacitance below 1000 pF. Also, use a 1-Wire bus master that can handle the capacitive load.
The maximum cable length for the 1-Wire bus depends on the cable capacitance and the bus speed. As a general rule, keep the cable length below 100 meters for reliable operation.
Implement error detection and correction mechanisms, such as CRC checks and retries, to handle errors during data transmission over the 1-Wire bus.
Yes, the DS1721S supports multi-drop configuration, where multiple devices can be connected to the same 1-Wire bus. Each device must have a unique ROM code to ensure proper addressing.
