ST10F272B/ST10F272E
Single CAN bus
The single CAN Bus multiple interfaces configuration may be implemented using two CAN
transceivers as shown in
Figure 13. Connection to single CAN bus via separate CAN transceivers
The ST10F272 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.
