Sleep mode current consumption

[Tanushree]

Hello Team,

Please suggest which should be disabled in the processor to minimize current consumption in sleep mode. We only need the accelerometer and ignition to trigger wakeup through interrupts, while all other functionalities should be turned off.

Hi,

Thank you for your interest in NXP Semiconductor products,

You would be looking to keep the processor at one of the following Low Power Key States.

And also look at the available APIs from reference manual that you can use to save power when triggering the DSM.
