Dear sir or madam

I  want to check the S32K148 in the lower power mode consumption.

  • The MCU needs to implement the timer wake-up function and the GPIO port wake-up function.

 

 could you help me to solve this problem ,thanks.

Hi@qianqin_wang

You can find the following routines in our S32 DS

The following link is a Chinese document and tutorial, you can refer to learn about the low power consumption of S32K1

Hi Senlent

thanks for your reply , i also want to check why at the same temperature,the current is different.

for example: the S32K148 the typ ad max value is different at the same temperature,what the reason that makes the current is different?

Hi@qiaoqin_wang

Because the test conditions are inconsistent,

You can see from the title that although they all work in VLPS mode, some peripherals are turned on or off.

You can find the details in the appendix of the data sheet.

hi @Senlent 

Thank you for your reply. Could you tell me which module is working in VLPS mode and what is the corresponding current? Can you make a comparison under the same temperature?

Hi@qiaoqin_wang

Please try to use this tool to see the power consumption.

Or you can check our datasheet.
