This document explains how to migrate a microcontroller application based on STM32F1 series to STM32F2 series, including hardware migration, peripheral migration, and firmware migration.
This document provides a comprehensive guide for engineers looking to migrate existing designs based on the STM32F1 microcontroller family to the newer STM32F2 series. It addresses the need to replace components due to growing product requirements or cost reduction objectives.
The note details the necessary steps for hardware migration, including pinout differences and power scheme variations between the two families. It also covers peripheral compatibility, system architecture changes such as the 32-bit multi-AHB bus matrix, and specific firmware migration strategies using libraries.
This document helps designers analyze the steps needed to migrate from an existing STM32F1 design to STM32F2 devices.
To migrate your application, you have to analyze the hardware migration, the peripheral migration and the firmware migration.
Yes, all functional pins are pin-to-pin compatible in the STM32 F1 series and STM32 F2 series.
