Saving power consumption with Ethernet communication

Hi,

 

Our product design is started with IMX6DL.

Now, I have a requirement that

"power consumption of our product is less than 2W while waiting for Power-On command from external controller during standby mode"

To satisfy this requirement, do we have any method to save IMX6DL power consumption as long as possible? 

 <Example>

 IMX6 works with low clock mode, or providing power supply voltage to only related IF, such as NVCC_RMII

And, please refer below diagram for your understanding.

Best regards,

Yuji

Hi Yuji

I am afraid power consumtion data for such use case is not available.

Available power consumption data can be found in AN4576, please pay

attention to sect.4 Reducing power consumption

i.MX 6DualLite Power Consumption Measurement

>IMX6 works with low clock mode, or providing power supply voltage to only related IF, such as NVCC_RMII

for i.MX6DL all power supplies should be on even for unused modules.

For requirement "power consumption of our product is less than 2W" may be recommended to

apply to Professional Services Software Technologies Form | NXP Semiconductors 

as many customers achieved necessary power numbers making various software optimizations

using this service.

Best regards
igor

Hi, Igor

Thanks for your reply.
If we realize to reduce power consumption by entering low power mode, some of mode still can use RMII function?

Is this regardless of power mode?
