What's the correct power consumption on STM32F413

Hi all:

The document says the power consumption is 112 uA / MHz.

But the power supply has offered 56mA current.

I measure the  IDD pin, the result is only 16 mA.

Is the consumption due to  ST-Link part ?

If yes, could I cut off the ST-Link part?

Thank you in advance.

The datasheet contains multiple power consumption scenario. Find the entry which is closest to your situation (supply, MHz, peripheral on or off, etc..) What is on a datasheet is guaranteed and more specific. (let's say second order of precision). I haven't looked at the schematic to understand where the current is going after the jumper... check it out.
