CAN Interface

The CAN Interfaces use the TJA1040 CAN driver (U9) for CANH1 and CANL1, and TJA1040 CAN driver (U10) for CANH0 and CANL0 on the MCB2470 board.

The jumpers at CAN#1 (J18, J19) connect P0.0 and P0.1 to either the CAN0 transceiver or the IrDA transceiver. The jumpers at CAN#2 (J16) connect P0.4 and P0.5 to the CAN1 transceiver.

The CAN terminal block connector allows access to both CAN channels 0 and 1 as shown in the figure below.

  • CAN termination resistors make it easy to connect the MCB2470 board to your CAN network but they are not always required. When connecting the MCB2470 Board to a CAN network, you may need to remove the termination resistors.
