TCAN1044-Q1: VIO question

Part Number: TCAN1044-Q1

Dear team,

If MCU's TX/RX is 3.3V, we just need to power VIO=3.3V, then there is no need to add a level shift between MCU's TX/RX and TCAN1044V-Q1's TX/RX, right?

Thanks & Best Regards,

Sherry

    Hi Sherry,

    You are correct, the VIO pin provides a digital IO voltage to match the CAN controller voltage, removing the need for a level shifter. Just as it shows in the diagram you would just connect the CAN controller VDD and the TCAN VIO to the same power supply output.

    Best,
