[M482] SPD0 Power consumption

MCU: M482ZGCAE

Set PA.12, PC.1, PB.2 as wake up source at Stand-by Power down mode.

PB.1 is wired to the analog signal.


Set MCU to SPD0, then Enter to Power-down mode. The measured current about 145uA.


When I remove the analog signal from PB.1, the measured current will down to  40uA.

Similarly, do not set PB.2 as the wake-up source, the measured current will down to  40uA.


I must sample the analog signal from PB.1. How can I do to reduce the current consumption?
