Measurement Schematic, External Core Supply

The values in 

 are measured values of power consumption under the following

conditions.

• Operating conditions internal core supply (

= 1.62V, supplied by the internal regulator

– Corresponds to the 3.3V supply mode with 1.8V regulated I/O lines, please refer to 

the Supply and Startup Considerations section for more details

• Oscillators

– OSC0 (crystal oscillator) stopped

– OSC32K (32KHz crystal oscillator) running with external 32KHz crystal

– DFLL running at 50MHz with OSC32K as reference

• Clocks

– DFLL used as main clock source

– CPU, HSB, and PB clocks undivided

• I/Os are inactive with internal pull-up

• Flash enabled in high speed mode

• POR33 disabled

Consumption active is the added current consumption when the module clock is turned on and
the module is doing a typical set of operations
