Dear support team,
Are there some differences between the S32K144 and S32K146 very low power mode (VLPS) ?
I use this sequence to go to very low power mode:
During the initialization:
When I want to to go very low power mode:
With my hardware with S32K146, the current consumption in sleep mode is 5mA higher than with the other hardware (with S32K144).
is this normal that the S32K146 consumes 5mA more than the S32K144 (in VLPS or RUN mode) ?
Thank you very much
Hello,
As per S32K1xx Datasheet, the consumption in VLPS of S32K146 is slightly higher (+20uA, Table 7 of DS) than the consumption of S32K144.
5mA is really too much.
The board must run stand-alone without debugger to enter VLPS.
Can you check VLPSA bit? Do you drive any external load?
Regards,
Daniel
