CAN bus configurations
Depending on application, CAN bus configuration may be one single bus with a single or
multiple interfaces or a multiple bus with a single or multiple interfaces. The ST10F276Z5 is
able to support these two cases.
Single CAN bus
The single CAN Bus multiple interfaces configuration may be implemented using two CAN
transceivers as shown in
Figure 20. Connection to single CAN bus via separate CAN transceivers
The ST10F276Z5 also supports single CAN Bus multiple (dual) interfaces using the open
drain option of the CANx_TxD output as shown in
Connection, only one transceiver is required. In this case the design of the application must
take in account the wire length and the noise environment.
