DS28E17

1-Wire-to-I²C Master Bridge

General Description

The DS28E17 is a 1-Wire slave to I C master bridge

device that interfaces directly to I C slaves at standard

Beneﬁts and Features

● Converts 1-Wire Communication Protocol to I C

Master I/O

(100kHz max) or fast (400kHz max). Data transfers seri-

• Operates I C Slave Peripherals over the Single-

ally by means of the 1-Wire protocol, which requires only

Contact, 1-Wire Interface

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 net-

work. Multiple DS28E17 devices can coexist with other

devices in the 1-Wire network and be accessed individu-

ally without affecting other devices. The DS28E17 allows

● Extend I C Communication Distance with 1-Wire Protocol

• 100 Meters (typ) in Standard Speed for a

Properly Conﬁgured Network

● Flexible 1-Wire Slave and I C Master Operational Modes

• Supports 15kbps and 77kbps 1-Wire Protocol with

Packetized I C Data Payloads

using complex I C devices such as display controllers,

• Factory-Programmed, Unique 64-Bit 1-Wire ROM

ID Provides Unalterable Serial Number to End

Equipment

• Standard 100kHz and 400kHz Communication

Rates for I C

• I C Clock Stretching Automatically Supported

ADCs, DACs, I C sensors, etc. in a 1-Wire environment.

Each self-timed DS28E17 provides 1-Wire access for a

single I C interface.

Applications

● Accessory Identiﬁcation and Control

● Low Power Consumption

● I C Sensors

• 0.3µA (typ) in Sleep Mode

• 2.6mA (typ) when Operational

● Display Controllers

● ADCs/DACs

• Separate Pins for Sleep and Wakeup Flexibility

• Remote Power Controlled by an Awake Pin

• Sleep Mode Enabled by Sleep Pin or a 1-Wire

Device Command

Ordering Information appears at end of data sheet.

● Easy to Integrate

• 3.3V(nom) Supply, Small 4mm x 4mm x 0.75mm

TQFN Package, -40°C to +85°C Operation

• Evaluation HW and SW Available
