S32K312NHT0MPAST SBC question

hyjung — Fri, 23 Jun 2023 04:41:40 GMT

Hi team

The customer is looking for an SBC that will only supply adequate power to the S32K312NHT0MPAST.
Is UJA1169 possible??
If so, how do you handle unused pins (ex. CAN Tx/Rx, CANH, CANL) because only simple power is used?

Thanks.

Hello,

Thank you for using the NXP community.

I do recommend reviewing the S32K3 evaluations boards as a reference for your design.

As you noticed, all the solutions include a Safety SBCs (FS26) which is highly recommended to supply your MCU. The SBC or PMIC performs observations and control functionalities that are essential to fulfill some related functional safety requirements.

I hope this information helps.
