ST10F269
The ST10F269 also supports single CAN Bus
multiple (dual) interfaces using the open drain
option of the CANx_TxD output as shown in
Figure 48. 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.

Multiple CAN Bus
The ST10F269 provides 2 CAN interfaces to
support such kind of bus configuration as shown
in Figure 49.
