Technical note
Migrating from STM32L15xx6/8/B to STM32L15xx6/8/B-A and from
STM32L100x6/8/B to STM32L100x6/8/B-A
Introduction
To ease the development of STM32 microcontroller applications, it is important to be able to
smoothly replace one microcontroller type with another from the same product family. The
purpose of this technical note is to help the users with the migration from an existing
STM32L15xx6/8/B device to an STM32L15xx6/8/B-A device and from an existing
STM32L100x6/8/B device to an STM32L100x6/8/B-A. This document includes the relevant
information for the users.
Prior to migrating an application, the users need to analyze the hardware migration, the
peripheral migration and the firmware migration. To best understand the information
included in this technical note, the user should be familiar with the STM32L1 microcontroller
family.
