9.3
Run Mode Current/Power consumption
The power dissipation during normal operation is determined by the total power dissipation of the internal logic
PC, the dissipation from analog modules PA and the power dissipation PIO of the I/O buffers. Among the I/O buff-
ers the dissipation caused by the stepper motor drivers PSMC should be taken into special consideration.
So the overall power consumption PD will be calculated as a sum of Pc + PA + PIO .
9.3.1
Logic Power Consumption
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:
Icc
= 3.45[mA/MHz] * CLKB[MHz] + 2.52[mA/MHz] * CLKP[MHz] + 0.72[mA/MHz] * CLKT[MHz] + 35.5 mA.
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:
.
Note: Higher frequency settings cannot be allowed in the package currently used. For higher frequency
settings the maximum power consumption would exceed the maximum allowed value of 1.33W.
In addition to this power consumption of the MCU core logic the following contributions to the overall power con-
sumption have to be considered:
