Master bridge interfaces directly to I2C slaves at standard or fast rates

The Maxim Integrated DS28E17 1-wire-to-I2C master bridge is now available from Mouser. The device interfaces directly to I2C slaves at standard (100kHz max) or fast (400kHz max) rates. 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, 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 and ADCs/DACs.
