DS28E17Q+

DS28E17Q+ is a 1-wire peripheral to I2C controller bridge device that interfaces directly to I2C peripherals. Data transfers serially by means of the 1-Wire® protocol, which requires only a single data lead and a ground return. It 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, etc. in a 1-wire environment. Each self-timed DS28E17 provides 1-wire access for a single I2C interface. Applications include accessory identification and control, I2C sensors, display controllers, ADCs/DACs.
