IMX8M MINI Power Consumption Calculations

Hi,

Could you please let me know, How to calculate the power consumption in IMX8M mini processor, I have an IMX8M mini design. The peripherals only use a camera with a CSI interface and Micro SD card. The power consumption of this design is a bit large, reaching 3.2W. So how to Reduce SoC Power when only Running A53 on i.MX8M mini.

Thank & Regards,

You can see the application note https://www.nxp.com.cn/docs/en/application-note/AN12410.pdf

Thank you,

This is a good reference, we are testing.

Hi NXP team,

We are using 'MIMX8MM5CVTKZAA' part in our design, without VPU.

The attached Appnote AN12410 is a good reference point for our design.

Appnote provides all the relevant power consumption for 'VDD_GPU_VPU_DRAM' power supply rail. If VPU is not being used, how shall we treat power consumption on these rails.

For example, Table-3 'IDLE_DEFAULT' condition in the appnote has a total current on 'VDD_GPU_VPU_DRAM' as 402 mA.

How shall we consider the current?

1. 402 mA current on each VDD_GPU and VDD_DRAM power supply rails. 0mA on VDD_VPU.

2. 201 mA current on each VDD_GPU and VDD_DRAM rails and 0mA on VDD_VPU.

Regards,

Mihir
