Current Consumption
The purpose of the Current Consumption table is to support board power design and power module
selection.
.
Notes:
1.
Current in mA is calculated using maximum recommended VDDIO specification for each power
rail.
2.
All output clocks toggling at their specified rate.
3.
Maximum drawn current from the power supply.
