Abstract

This application note assists with migrating from Microchip's 8-bit AVR® MCU platform to the Texas Instruments Arm® Cortex®-M0+ MSPM0 MCU ecosystem. This guide introduces the MSPM0 development and tool ecosystem, core architecture, peripheral considerations, and software development kit. The intent is highlight the differences between the two families and to leverage existing knowledge of the Microchip AVR® ecosystem to quickly ramp with the MSPM0 series of MCUs.
