AM625: Low Power Modes (power and timing questions)

Hello Mari Tsunoda

Thank you for the query.

Mari Tsunoda said:

With regards to active mode, what % power consumed can be reduced in each of the three modes noted above?

The SoC used case is customer dependent and i am not sure if there is a way to answer the question.

Let me reassign to the expert.

Hi Mari,

In standby mode we are targeting <100mW,  MCU Only we are targeting under 125mW, and Deep Sleep under 20mW.

I will need to loop in a software expert to clarify the latency times, for your second question.

Colin

Hi Mari,

How long does it take to become active from the three modes above?

It depends where the ending point of the measurement is, any of the kernel module, user space application or the Linux prompt?

Do you have any detail from the customer, any resume latency requirement?

Hi Bin,

Will check with customer and get back to you.

Best,

Mari

Hi Bin,

In the document that I sent you privately ,what is the end point of the wake-up time measurement?

Best regards,

Mari

Hi Mari,

I believe the document shows the resume time in the hardware point of view. It doesn't include the resume time required in software.

Typically the resume time in Linux would be 100ms or more depending on the measurement point and Linux configurations.
