Power Consumption
This section details the power consumption of the device as measured during various modes of operation. Power con-
sumption values are provided for both the device-only, and for the device plus Ethernet components. Power dissipation
is determined by temperature, supply voltage and external source/sink requirements.
7.3.1
POWER CONSUMPTION - INTERNAL REGULATOR DISABLED
7.3.1.1
SUSPEND0 - Internal Regulator Disabled
7.3.1.2
SUSPEND1 - Internal Regulator Disabled
7.3.1.3
SUSPEND2 - Internal Regulator Disabled
Note:
All current consumption and power dissipation values were measured with VDD33IO and VDD33A equal
to 3.3 V.
