DATASHEET
Note: The current at VDD_CORE is either supplied by the internal regulator from current entering at
VDD33, or from an external 1.8V supply when the internal regulator is disabled.
Note 7.1 This is calculated with full flexPWR features activated: VDDIO = 1.8V and internal regulator
disabled.
Note 7.2 Current measurements do not include power applied to the magnetics or the optional
external LEDs. Current measurements taken with VDDIO = +3.3V, unless otherwise
indicated.
