Abstract

The MSPMx Arm device family provides a high degree of pin-to-pin compatibility. MSPM0Gx51x and MSPM33C32xx share many packages and features which make migrating between these devices a simple process. It is possible to design a single printed circuit board (PCB) to accommodate both MSPM0Gx51x and MSPM33C32xx. This application note will discuss hardware considerations to enable seamless migration and PCB drop-in replacement between both devices.
