Current consumption measurement value of GPIO with HYS bit enable.

[takayuki_ishii]

Hello community,

In application note "Influence_of_PinSettingOnSystemFunction_AN5078.pdf"

It have a comment about HYS setting as following,

Compared to the CMOS configuration option, the HYS one slightly increases the pin power consumption
as well as the propagation delay by several nanoseconds.

It seems that it is different some DC parameter between CMOS input and HYS.

Don't you have a some data to measure a input current with HYS setting?

We need a DC Parameters with HYS setting like a Table 22 of datasheet IMX6DQAEC Rev. 5, 09/2017.

Best regards,

Ishii.

Hello igorpadykov‌

I'm very sorry my insistent question.

Our customer hope to clear about meaning of following sentence in AN5078.

   "Compared to the CMOS configuration option, the HYS one slightly increases the pin power consumption

    as well as the propagation delay by several nanoseconds."

In this sentence,

  "slightly increases the pin power consumption" mean that is

    not Input current but current of Power Group for each IO pin.

Is it correct?

If so,

  current of Power Group will be increase by HYS setting but very slightly.

  So you say that

   "In i.MX6DQ power consumption differencies related to HYS are very
    small and not specially specified."

Is it correct?

I  am looking forward to hearing from you.

Best regards,

Ishii.

Hello Igor,

Thank you for your quick response.

I will answer it to my customer.

Best regards,

Hello Igor,

Thank you for your reply.

I understand that Table 22 can applied bot CMOS and HYS input.

Could you add a comment to the table or footnote about it?

Best regards,

Ishii.

Hi Ishii

not sorry, all parameters which were characterized for chip are already provided in datasheet.
Also input current does not depend on HYS setting.

>We need a DC Parameters with HYS setting like a Table 22 of datasheet IMX6DQAEC Rev. 5, 09/2017.

sorry such parameters are not available. Please note that AN5078 just gives description of IP
GPIO module "in general". In i.MX6DQ power consumption differencies related to HYS are very
small and not specially specified.

OK, I under stand that it have no parameters for HYS setting.

Can Table 22 of datasheet be applied both CMOS and HYS input?

Best regards,

Ishii.

Hi Ishii

yes Table 22 of datasheet can be applied for both CMOS and HYS input.
