Migration of microcontroller applications from STM32F7 Series to STM32H743/753 line

PublishTime：2021-12-09

■Designers of STM32 microcontroller applications must be able to easily replace one microcontroller type with another one from the same product family, or products from a different family. The reasons for migrating an application to a different microcontroller can be for example:
●To fulfill extended product requirements, extra demands on memory size, or an increased number of I/Os.
●To meet cost reduction constraints that require a switch to smaller components and a shrunk PCB area.
This application note analyzes the steps required to migrate from an existing STM32F7 Series to a design based on an STM32H743/753 line device.
This application note provides a guideline on both hardware and peripheral migration. To better understand the information inside this application note, the user should be familiar with the STM32 microcontroller family.
