6.5 Current Consumption Graphs
A. Test conditions are as defined in Table 6-5 for operational currents under nominal process voltage and temperature
conditions.
B. I
DD
represents the total current drawn from the 1.8-V rail (V
DD
). It includes a trivial amount of current ( < 1 mA) drawn
by V
DD1
.
C. IDDA represents the current drawn by VDDA1 and VDDA2 rails.
D. Total 3.3-V current is the sum of I
DDIO
, I
DD3VFL
, and I
DDA
. It includes a trivial amount of current ( < 1 mA) drawn by
VDDAIO.
