S32K344 interface for 5V SENT protocol signal

How do you correct interface the NXP S32K344 for a 5V SENT signal?

AN4856: MPC574xP SENT/SPC Driver – Application Note (nxp.com) gives a very good diagram of the interface, but the S32K344 is a 3V3 powered MCU and so do you need to have a simple voltage divider on 5V SENT signal ?

Hello @Pinderloo,

S32K344 can be powered by 5V.

If you need it to operate at two voltage levels, you can use the design from the AN or an active voltage level translator, this is down to the user.
