1-Wire

A half-duplex serial bus from Maxim Integrated Products, Sunnyvale, CA (www.maximintegrated.com). It was originally developed by Dallas Semiconductor, which was acquired by Maxim in 2001. Using one line for data and power, plus ground, 1-Wire is widely used to transfer identification and calibration data from products such as battery packs, printer cartridges, medical sensors, printed circuit boards and cellphone accessories. Transmitting at 16 or 142 Kbps, each 1-Wire device has a unique serial number.

1-Wire is used to transfer data from Maxim's iButton chips, which are portable tokens used for building access, asset management and other tracking and monitoring applications (see iButton).
