Real-time / On the Move

Ethernet can deliver ubiquitous solutions across all applications


Ethernet On Board Diagnostics (OBD)

Increases speed vs CAN Flash car in minutes not hours

Reduces costs for OEMs

ISO 13400: Diagnostics over IP (DoIP)

100BASE-TX Ethernet

ISO 15031-3 / OBD II connector (not RJ45!)

Micrel pioneered Ethernet OBD • Long-term close relationships with OEMs • First to market with AEC-Q100 Ethernet


Example In Vehicle Networking (IVN) today

Multiple buses

Adds complexity & cost


Ethernet delivers Network Ubiquity

Single media: • Eliminates bridging gateways • Reduces complexity & cost


There are currently over

cars supporting Micrel Automotive Ethernet inside

8 Million

But this is just the beginning

Ethernet is now ‘on the move’!


Automotive Ethernet ‘On the Move’

ADAS Infotainment Diagnostics OTG

Vehicle is moving

Stringent EMC requirements

Real Time: Deterministic Networks

ADAS exemplifies the major challenges for In-Vehicle Connectivity


Why Ethernet for ADAS?

Lower cost: unshielded cable

No cables for power: PoE

Ubiquitous network across multiple domains
