75 / 179 page ST10F273E CAN modules 75/179 17.2 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 ST10F273E 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 11. Figure 11. Connection to single CAN bus via separate CAN transceivers The ST10F273E also supports single CAN Bus multiple (dual) interfaces using the open drain option of the CANx_TxD output as shown in Figure 12. Thanks to the OR-Wired 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. Figure 12.
