Binary compatibility between F091 and G0B1 series

[ABish.1]

Due to dwindling stock levels we need to migrate from a F091 to a G0B1 series microcontroller. To keep compatibility for devices in field(for future firmware upgrades) I was wondering if it was possible to run the same code binary between the two microcontroller series. Moreover what options do we have if any to be able to keep the same firmware binary while moving to a new microcontroller.

Hello @ABish.1​ 

Please refer to Application AN5145 “Migration of applications from STM32F0 Series to STM32G0 Series “

The section 5 describes how to migrate an application based on STM32Cube MCU Package.

You can also use the STM32CubeMX tool, which offers the features to compare the characteristics of two or more MCUs through the "Cross Selector" tab, and to display the list of compatible MCUs, then export your current project configuration to a compatible MCU.

I advise you to refer to the UM1718 in section "Cross selector" and "Tutorial 5: Exporting current project configuration to a compatible MCU",
