Internal regulators specification for I.MX6x

Hi,

I'd like to get your advises about internal regulators requirement.

I found below table on Hardware Development Guide for i.MX 6DualPlus/6QuadPlus, 6Dual/6Quad and i.MX 6Solo/6DualLite Applications Processors,

what is the meaning of this output voltage? This means minimum, or typical?

And, this power requirement for which series of I.MX6? Quad?Dual Lite? ,or the others?

Actually, what this table want to describe?

Hello,

The mentioned table provides some nominal values for reference.

Refer to i.MX6 Datasheets and RMs for more details regarding the LDOs.

i.MX 6 Series Applications Processors | Multicore Arm Cortex-A7/A9/M4 | NXP

Have a great day,
Yuri

Hi, Yuri

Thanks for your answer.

And, please let me ask you about another question.

I found below table at page.7 on AN4576.

VDD_ARM_CAP voltage at 396MHz is 0.95V, but I think that is not satisfied with below operating ranges described on datasheet.

VDD_ARM_CAP=1.125V minimum

Could you teach me the detail about VDD_ARM_CAP requirement?

Hello,

Use specifications of the recent (i.MX 6 S/DL) Datasheet(s). The data of the app note

are obsolete.

Regards,

Yuri.

Hi,

I referred to below;

=============

●Datasheet - IMX6SDLCEC Rev. 9, 11/2018

　https://www.nxp.com/docs/en/data-sheet/IMX6SDLCEC.pdf

This revision is old?

●AN - AN4576 Rev. 1, 3/2013

　https://www.nxp.com/docs/en/application-note/AN4576.pdf

This revision is old?

=============

Both document is posted on NXP website.

Which document should I refer to?

Br,

Yuji
