DCAN250 - CAN over Battery

Power Line Communication

Preliminary Information

Description

The DCAN250 is a VLSI device for Multiplex CAN bus communication over battery Power Lines (PLC). It

is a complete transceiver solution for CAN bus alternative physical layer between for a wide range of

vehicular modules such as the steering wheel, doors, sensors, displays, Internet/navigation computer,

security, control panel, etc.

The device operates as a smart DC - PLC transceiver for CAN bus controllers. The DCAN250 contains a

modem, a channel coder/decoder (ECC), a communication controller, and a message-buffered host

interface to overcome the hostile environment of vehicle battery lines. A Sleep Mode reduces the power

consumption when no bus communication exists. The DCAN250 is based on the DC-BUS technology,

that reduces harness weight whilst enabling flexible, quick and simple installation.

Applications

• Vehicle electronics

• Car audio control

Features

• Noise robust up to 250Kbps communication over a battery power line.

• Reduces harness weight, eliminates complex cables and installation.

• Vehicle data surveillance • Flexible installation operates over 12V to 42V battery lines.

• Mobile computing

• Mobile phone interface

• Security systems

• Receives and transmits CAN bus protocol.

• Peer to Peer, up to 16 devices, multi-user packet communication.

• Opens new dimensions for car electronics design.

• Sleep Mode for low power consumption.

• Internal communication
