Question, VDD_SOC and VDD_PU of i.MX6DL

[SLICE]

Dear team,

My customer found the following description on your i.MX6Solo/DualLite/Datasheet(IMX6SDLCEC,Rev.9).

“VDD_SOC LDO output set point is equal to the VDD_PU LDO output set point.”

The VDD_PU is the power for graphics feature and they do not use it, then they use the VDD_PU_CAP outputs voltages is about 0.15V and VDD_SOC and VDD_PU is differ.

Is it possible to use VDD_PU as like this even Graphic feature is not used?

Best Regards,

Miyamoto

Hello,

  According to the Datasheet VDD_SOC LDO output set point must be set equal to

the VDD_PU LDO output set point (in LDO enabled mode) without any relation whether

GPU is used or not. 

Have a great day,

Yuri
