## How to get Maximum Supply Currents

Hi all

As for the "Table 14. Maximum Supply Currents" in IMX6SXCEC.

It's not mentioned about how to get a value.

I found a calculation formula for i.MX6Q from following thread in i.MX community.

About max supply current in i.MX6Q.

The formula is as follow.

--------------------------------------------------

General equation for estimated, maximum power consumption of an IO power supply:

Imax = N x C x V x (0.5 x F)

Where:

N—Number of IO pins supplied by the power line

V—IO voltage

(0.5 xF)—Data change rate. Up to 0.5 of the clock rate (F)

In this equation, Imax is in Amps, C in Farads, V in Volts, and F in Hertz.

--------------------------------------------------

Is the formula appropriate to i.MX6SoloX ?
