Power Consumption Calculations
To calculate the estimated power consumption of the 1.8 VCCINT core power, the
Power tab uses the following formulas to arrive at the results after clicking Calculate:
■
■
For example:
You can apply the same formulas to the VARIABLE VCCIO power estimation
calculation:

Current across Rsense (R44) = Voltage drop across Rsense/Rsense resistance
Power consumption of V
Rsense
Current across Rsense (R44) = (0.756 mV)/(0.27) = 2.8 mA
Power consumption of V
Current across Rsense (R47) = (0.332 mV)/(0.27) = 1.23 mA
Power consumption of V
TP1-TP2—Allows you to enter the value recorded from the multimeter.
Result—Shows the calculated power consumption after clicking Calculate.
Calculate—Perfoms calculation for estimated power consumption.
TP3-TP4—Allows you to enter the value recorded from the multimeter.
VAR VCCIO—Allows you to select the voltage level that matches the current
setting on J8 on the development board.
Result—Shows the calculated power consumption after clicking Calculate.
Calculate—Perfoms calculation for estimated power consumption.
