The power dissipation during normal operation is determined by the total power dissipation of the internal logic
P
the dissipation caused by the stepper motor drivers P
So the overall power consumption P
The following formula can be used to calculate the maximum core current consumption when the PLL is used
depending on the frequency settings for the internal clocks :
I
The factors B, P, and T depend of the device, see table “Current consumption factors”.
If clock modulation is used the following value must be added to this result : 0.24 [mA/MHz] × CLKB [MHz].
This results in the following values (higher clock settings are not allowed) :
CC
C
, the dissipation from analog modules P
= B × CLKB [MHz] + P × CLKP [MHz] + T × CLKT [MHz] + 35.5 [mA]
