Note 7.3

 

 

 

 

 

 

 

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.
