Hello,
I am trying to reach the datasheet consumption values with the Freedom eval board, but I don't manage it.
On the different low leakage stop mode I measure 2.8uA added in comparison to datasheets values, except on VLLS0 where I have 300nA added.
The fact that I get a closer result on VLLS0 make me think that there is no external leakage on the board, but the 2.8uA configuration for the other modes is still important. I guess I am wrong in the configuration and forget something to reach optimal value.
Do you have an idea of the potential source of that extra consumption?
In my code, I just disable watchdog and clock monitoring and go to the desired Stop mode.
Thank you for the help.
Antoine

Hi Antoine, besides disabling the watchdog, there are some other things you need to take into consideration to achieve the power consumption figures depicted in the datasheet, please take a look at our Low power management application note for kinetis architectures:
