Car ECUs do not need to be

permanently active, for this

reason the concept of partial

de-activation of bus systems

(Partial Networking) has been

introduced.

A dedicated specification for

the selective wake-up of HS-CAN

transceivers has been defined

(ISO 11898-6) supporting the

novel bus concept.

STMicroelectronics has actively

participated in the group

working on the ISO specification,

developing one of the first

products that support Partial

Networking.
