Abstract

MSPM0Gxx series microcontroller (MCU) portfolio is a sub family of MSPM0, which offers a wide variety of 32-bit MCUs with ultra-low-power and integrated analog and digital peripherals for sensing, measurement and control applications. Reducing power consumption while performing complex real-time applications presents a major challenge for the recent embedded applications. This article was created to build a simple framework to help developers understand the MSPM0Gxx series low-power features, how power can be optimized to meet the specific needs based on MSPM0 and how to evaluate and measure it.
