About the NVCC_DRAM_CKE Power supply for i.MX7

Dear all,

 

We want to cut down on power consumption at the time of the standby in the system.

We want to completely power off the i.MX7 and to enter DDR in Self Refresh mode.
The wake-up of i.MX7 is only POR.

 

In this case do we have only to supply power to NVCC_DRAM_CKE to keep a logic of CKE?
Can we power off the VDD_SNVS_IN?


We tried this constitution and see it to work well.
Does i.MX7 allow this operation?

Best  Regards,
Yuuki
