Dear team,

I would like to ask about power consumption of i.MX8M.

There is no VPU for i.MX8M QuadLite(i.MX8MQL).

Could you show me whether if i.MX8MQL dissipate power for VPU?

My customer could not find the description about that on your datasheet.

But they think i.MX8MQL will not dissipate power for VPU.

And please let me know if powering VPU is needed also for i.MX8MQL?

 

Thanks,

Miyamoto

Hi Miyamoto

yes this is correct

>And please let me know if powering VPU is needed also for i.MX8MQL?

it is not needed. VDD_VPU can be left unconnected according to
Table 29 – i.MX8M Unused Power Rail Strapping Recommendations
i.MX8M Hardware Developer’s Guide
