2.4.7 CAN

This reference design supports the CAN interface using a TCAN1043 and TCAN1042. The TCAN1043 transceiver supports CAN-FD functionality and meets the requirements of the ISO 11898-2. The device has wakeup pin support enabling DRA829/TDA4VM wakeup without need for an external MCU. CAN wakeup integration details as follows:

  • Mode 1: OFF
  • Mode 2: Wakeup
    • CAN module is in standby mode. Signal can wake up CAN which in turns on PMIC and rest of the board.
  • Mode 3:ON
    • CCARD is ON and fully functional

The TCAN1042 transceiver supports CAN-FD functionality and meets the ISO 11898-2:2016 and ISO 11898-5:2007 Physical Layer Standards
