PMIC for LS1024A

Hello,

If we want to select your PMIC for LS1024A, which parts we can use?

I know RDB board doesn't use PMIC for LS1024A, so FSL may not test your PMIC with LS1024A.

Thanks,

Hello Seguei-san,

Thank you for your answer.

I think that power up and down sequence of LS1024A is slightly complex comparing to other Layerscape devices.

NXP verified that VR500 could work with power up/down sequence of LS1024A? 

Usually, NXP offers several  parts number of VR500 for specific LS series. (for LS1021A, for LS1043A)

But I can't find the parts number for LS1024A. It means must we program VR500  (voltage and power-up/down sequence) for LS1024A on our side?

Thanks,

Norihiro Michigami
