About current consumption

Hello.

I want to check about i.MX6Q.

There is not a mention of the current consumption of each power supply.

(The power group described below.)

Could you tell me the maximam current consumption of each power ?

(In order to examine whether a VDDHIGH_CAP power supply can be used.)

・NVCC_ENET

・NVCC_LVDS2P5

・NVCC_RGMII

If you want to change in the use pin number of groups , please tell me the calculation formula.

Regards,

-okamoto

Hi Okamoto,

The current consumption of each power supply depends on the use case and what operations is each block of the processor performing at a specific time. Do you know AN4509? It's about current measurements in different use cases. It has a max power use case I think will be useful for you. You can also find more info in section 4.1.5 of the MX6QD datasheet.

Best regards.

Jorge.
