Figure 7-2. Measurement Schematic, External Core Supply
7.4.1 Peripheral Power Consumption
The values in Table 7-6 are measured values of power consumption under the following
conditions.
• Operating conditions internal core supply (Figure 7-1)
–V
VDDIN
= 3.0V
–V
VDDCORE
= 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
•T
A = 25°C
• 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.
