DS28E17 - 1-Wire-to-I2C Controller Bridge

General Description

The DS28E17 is a 1-Wire peripheral to I2C controller bridge device that interfaces directly to I2C peripherals at standard (100kHz, max) or fast (400kHz, max).

Data transfers serially by means of the 1-Wire® protocol, which requires only a single data lead and a ground return.

Key Features

  • Converts 1-Wire Communication Protocol to I2C Controller I/O.
  • Operates I2C Peripherals over the Single-Contact, 1-Wire Interface.
  • Extend I2C Communication Distance with 1-Wire Protocol.
  • 100 Meters (typ) in Standard Speed for a Properly Configured Network.
  • Flexible 1-Wire Peripheral and I2C Controller Operational Modes.
  • Supports 15kbps and 77kbps 1-Wire Protocol with Packetized I2C Data Payloads.
  • Factory-Programmed, Unique 64-Bit 1-Wire ROM ID P.

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.
