8.4 Current Consumption

The purpose of the Current Consumption table is to support board power design and power module

selection.

.

Notes:

1. Current in mA is calculated using maximum recommended VDDIO specification for each power

rail.

2. All output clocks toggling at their specified rate.

3. Maximum drawn current from the power supply.
