About flash clock maximum frequency.

[vienpeng]

I'm using S32K146H, according to the reference manual, the flash clock maximum frequency is 26.67MHz (in RUN mode). My question: In actual project, is it recommended setting the maximum flash clock frequency ? My project is applied in the field of automobile and battery management system.

Hi,

the microcontroller is designed to run continously at max frequencies, so there’s no need to decreased the flash clock. You can check Chapter 27: Clock Distrubution in the refefence manual:

There are examples of recommended configuration for individual modes.
