Can the main frequency of this chip reach 320M? Is Core_clk the main frequency on the configuration tool? This can only be configured to 160M, and I want to set the main frequency of this chip to the highest.

Hello @harryoceana,

It cannot operate at 320MHz.

Table 143. System clock frequency limitations (For S32K344, S32K324, S32K314, S32K342, S32K322, and S32K341).

Use one of the clock options:

24.7.2 System clocking configurations.

 

BR, Daniel
