L99PM72GXP Datasheet, PDF (1/2 Pages) STMicroelectronics – Car ECUs do not need to be permanently active

L99PM72GXP
CO₂ reduction enabled by
innovative car networking
L99PM72GXP extends ST’s automotive portfolio and is among the first ICs
in the market to support HS-CAN bus systems with Partial Networking
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.
