beCAN
The beCAN controller (basic enhanced CAN), interfaces the CAN network and supports the
CAN protocol version 2.0A and B. It has been designed to manage a high number of
incoming messages efficiently with a minimum CPU load.
For safety-critical applications the beCAN controller provides all hardware functions to
support the CAN time triggered communication option (TTCAN).
The maximum transmission speed is 1 Mbit.
