S32K1xx_Power_Modes_Configuration

Hi:

I'm testing the power consumption of S32K146 according to the table “S32K1xx_Power_Modes_Configuration” in the S32K1xx Family Data Sheet.

In the excel, there are 15 cases of power configuration,It's too complex to config every modules one by one.

So, Do you have the power consumption test sample program ?

Hi@945595199

1.I think you misunderstand the power-mode of S32K1xx.please refer to S32K-RM Chapter 39 for details.

2.there is an example "power_mode_switch_s32k1xx" in S32 DS for your reference.

The example documentation can be found in the S32 SDK documentation at Examples and Demos section. (<SDK_PATH>/doc/Start_Here.html)

BR!

Jim,

HI Jim：

I have looked at the demo program "power_mode_switch_s32k1xx" in the SDK directory, But it's how to switch modes. I want know how to configure the program with the power consumption measurement data mentioned in the "S32K1xx MCU Family Data Sheet.pdf".

1. Table 7 show the Power consumption in 15 cases.

2. Table 7's program configutation methons locate in the "S32K1xx_Power_Modes_Configuration.xlsx", the two picture below shows:

How to program S32K into these run state ?

Best Regards!~
