AM2431: Power Sequence

Shota Mago

Part Number: AM2431

Hi team,

My customer will use AM2431 and would like to clarify power sequence requirement.

Does below power sequence of AM2431 mean both following order are acceptable?
They’d like to make sure order of VDDS_DDR(1.1V).

Best regards,

Hello,

Looking at the power sequence diagram, the VDDS_DDR needs to come after the 1.8V supply is up. So the below is accurate where 1.1V comes after 1.8V.

Hi Antia,

Sorry, I had mistake for order of power sequence in the question.

I'd like to confirm both following order are acceptable.

Hi,

This is correct. You can use either order for the 1.1V and 0.85V.

Thank you,

Anita
