I want Advice on Optimizing Power Consumption for Low-Power MCU Projects

[ellaadams]

Hello All member,

I am working on a project that involves the use of a low power microcontroller from the NXP portfolio, the MCX family. The primary goal of my project is to design an energy efficient solution that can operate on a small battery for an extended period.

I have been experimenting with different ways to maximize power usage, like tweaking the frequency of the clock, using low power modes & controlling peripheral activity; I am still attempting to find the ideal mix between efficiency and performance.

Which low power mode would you recommend for a device that needs to wake up periodically to perform a brief task before returning to sleep?

How do you control clock speeds in your projects to cut down on power consumption without sacrificing the performance needed for particular tasks?

What strategies do you use to manage peripheral activity?

Can someone guide any tools & methods to accurately measure and profile the energy consumption of my MCU based project?

hi,ellaadams

The MCX C14x/24x/44x series microcontrollers are ideal for embedded applications that require low power consumption, flexibility, and cost effectiveness. The questions you raise are suggested in the introduction linked below.

Note about the source code in the document (nxp.com)This link explains The MCXC444 microcontroller family provides an explanation ultra-low-power feature for the power sensitive market. This MCU family implements several low-power modes to meet this  requirement. The application note provides detailed information about each power mode and includes case examples in the  SDK power mode switch example demo.

Wish it helps you.

If you still have question about it,please kindly let me know.
