This section details the worst case current consumption for each device power supply. These values
are provided to assist system designers with proper power supply design. These values cannot be
used to determine typical power consumption of the device. The maximum supply current for each
power supply is provided for the maximum VDDVARIO voltage in all supported ranges as detailed in
Table
