DS28E17 1-Wire-to-I²C Master Bridge

Analog Devices’ DS28E17 is a 1-wire slave to I²C master bridge device that interfaces directly to I²C slaves at standard (100 kHz maximum) or fast (400 kHz maximum). Data transfers serially by means of the 1-wire protocol, which requires only a single data lead and a ground return. Every DS28E17 is guaranteed to have a unique 64-bit ROM registration number that serves as a node address in the 1-wire network. Multiple DS28E17 devices can coexist with other devices in the 1-wire network and be accessed individually without affecting other devices. The DS28E17 allows using complex I²C devices such as display controllers, ADCs, DACs, I²C sensors, and more in a 1-wire environment. Each self-timed DS28E17 provides 1-wire access for a single I²C interface.
