This document describes the process of migrating between MSPM0Gx51x and MSPM33C32xx. This document can also be used in process of planning for a single design planning to use MSPM0Gx51x and MSPM33C32xx on the same printed circuit board (PCB).
Modern microcontrollers (MCU) contain an increasing amounts of features and peripherals. This can become a challenging during migration when determining which differences impact the performance or functionality of a system. To simplify the process, this document highlights differences between MSPM0Gx51x and MSPM33C32xx family of devices so that actions can be taken to enable a smooth migration or a single PCB design. This guide focuses on differences between the MSPM0Gx51x and MSPM33C32xx devices and can be used to migrate from either device family in any direction.
This guide is most effectively used ahead of the migration or design process. Follow the steps below to address each aspect of compatibility considerations between MSPM0Gx51x and MSPM33C32xx
