Total 3.3−V current
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.
