7.3 Power Consumption
This section details the power consumption of the device as measured during various modes of operation. Power con-
sumption values are provided for both the device-only, and for the device plus Ethernet components. Power dissipation
is determined by temperature, supply voltage and external source/sink requirements.
Note: All current consumption and power dissipation values were measured with VDD33IO and VDD33A equal
to 3.3 V.
