5.3 Power Consumption
This section details the device power measurements taken over various operating conditions. Unless otherwise noted,
all measurements were taken with power supplies at nominal values (VDDIO, VDD1A, VDD2A = 3.3V, VDDCR = 1.2V).
See Section 3.8.3, Power-Down Modes for a description of the power down modes.

Note 5-6 The curren
t at VDDCR is either supplied by the internal regulator from current entering at VDD2A,
or from an external 1.2V supply when the internal regulator is disabled.
Note 5-7 Cu
rrent measurements do not include power applied to the magnetics or the optional external LEDs.
The Ethernet component current is typically 41mA in 100BASE-TX mode and 100mA in 10BASE-T
mode, independent of the 2.5V or 3.3V supply rail of the transformer.
Note 5-8 Ca
lculated with full flexPWR features activated: VDDIO=1.8V & internal regulator disabled.
