In summary, the 1-Wire protocol is an efficient signaling scheme that multiplexes data and power onto a single bus, thereby minimizing interface complexity. The protocol is multi-drop capable with a single Master and or single or multiple Slave arrangement. Each Slave device is factory programmed with an unalterable ROM ID. With the search ROM capability the Master does not have to have prior knowledge of the Slave device ROM ID. Search Algorithms allow the device to learn IDs for all devices on network. Analog Devices offers a wide array of 1-Wire memory, secure authentication and mixed signal functions. Implementation of 1-Wire is as simple as using a spare microcontroller port pin to bit bang the 1-Wire line or using a protocol conversion line driver like an RS232 to 1-wire or I2C to 1-Wire device.
