Functional Description

The Controller Area Network (CAN) transceiver part of the SBC provides High-Speed (HS) differential mode

data transmission (up to 2Mbaud) and reception in automotive and industrial applications. It works as an

interface between the CAN protocol controller and the physical bus lines compatible to ISO 11898-2:2016 and

SAE J2284.

The CAN FD transceiver offers low-power modes to reduce current consumption. This supports networks with

partially powered down nodes. To support software diagnostic functions, a CAN Receive-only Mode is

implemented.

It is designed to provide excellent passive behavior when the transceiver is switched Off (mixed networks,

clamp 15/30 applications).

A wake-up from the CAN Wake Capable Mode is possible via a message on the bus. Thus, the microcontroller

can be powered down or idled and is woken up by the CAN bus activities.

The CAN transceiver is designed to withstand the severe conditions of automotive applications and to support

12V applications.

The transceiver can also be configured to Wake Capable in order to save current and to ensure a safe transition

from Normal to Sleep Mode (to avoid losing messages).
