Re: CAN Interface

<t>@ Donald,<br/> <br/> I'm new to CAN but I heard many people design automotive MCUs that needs a 5V CMOS device. As a know, CAN bus voltage level only up to 3.5V. Do you know why the MCU designers need a 5V CMOS device since 3.3V IO is ok to handle 3.5V range?<br/> <br/> Appreciate for the advice....
