About current consumption

okamotosatoshi — Thu, 20 Feb 2014 14:09:53 GMT

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,

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.
