1.1 Introduction

MSPM0 microcontrollers (MCUs) products are part of the MSP highly-integrated ultra-low power 32-bit MCU family based on the enhanced Arm® Cortex®-M0+ 32-bit core platform operating. These cost-optimized MCUs offer high-performance analog peripheral integration, support extended temperature ranges, and offer small footprint packages. The TI MSPM0 family of low-power MCUs consists of devices with varying degrees of analog and digital integration allowing engineers to find the MCU that fits a project's requirements. The MSPM0 MCU family combines the Arm Cortex-M0+ platform with an ultra-low-power system architecture, allowing system designers to increase performance while reducing energy consumption.

The MSPM0 MCUs offer a competitive alternative to the Renesas RL78. This application note assists with migration from RL78 MCUs to MSPM0 MCUs by comparing device features and ecosystems.
