DATASHEET

Note: The current 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 7.3

This is calculated with full flexPWR features activated: VDDIO = 1.8V and internal regulator
disabled.

Note 7.4

Current measurements do not include power applied to the magnetics or the optional
external LEDs.
