UC3D
• Temperature = -40°C to 85°C
32.5 Power Consumption
The values in Table 32-4 are measured values of power consumption under the following condi-
tions, except where noted:
• Operating conditions internal core supply (Figure 32-1) - this is the default configuration
–V
VDDIN
= 3.3V
–V
VDDCORE
= 1.8V, supplied by the internal regulator
– Corresponds to the 3.3V supply mode with 1.8 V regulated I/O lines, please refer to
the Supply and Startup Considerations section for more details
– The following peripheral clocks running
•T
A = 25°C
• Oscillators
– OSC0 running (external clock)as reference
– PLL running at 48MHz with OSC0 as reference
• Clocks
– PLL used as main clock source
– CPU, HSB, and PBB clocks undivided
– PBA clock divided by 4
– The following peripheral clocks running
• PM, SCIF, AST, FLASHCDW, PBA bridge
– All other peripheral clocks stopped
• I/Os are inactive with internal pull-up
