IMX6SoloX consumption calculation file for use conditions

[takashitakahash]

Hi, Community.

Our customer has question of about IMX6SoloX  consumption calculation file for use conditions.

Would you please give us  like a presentation of current consumption calculation file for use conditions or use case.

IMX6SXAEC Rev. 1, 9/2015 Datasheet  of p31 description of

Primary Interface (IO) Supplies are all "-" (bar),that represents what is mean?

Hi Takashi

"Supplies are all "-" (bar)"  means that there are no special conditions.

Regarding current consumption calculation one can use formula

i.MX6DQ Datasheet (rev.4, 7/2015) given at footnote 5

Table 8. Maximum Supply Currents

http://cache.freescale.com/files/32bit/doc/data_sheet/IMX6DQCEC.pdf

5 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

C—Equivalent external capacitive load

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.

May be useful AN5050 i.MX 6SoloX Power Consumption Measurement
