Technical note
Migrating from STM32L15/6xxD to STM32L15/6xxE
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 users with the migration from an STM32L15/6xxD
(348KB Flash) device to an STM32L15/6xxE (512KB Flash) device. This document includes
the relevant information for users.
Prior to migrating an application, users need to analyze the hardware migration, the
peripheral migration and the firmware migration. To better understand the information
included in this technical note, users should be familiar with the STM32L1 microcontroller
family.
For additional information, please refer to the STM32L100xx, STM32L151xx, STM32L152xx
and STM32L162xx advanced ARM^®-based 32-bit MCUs reference manual RM0038 in
which STM32L15/6xxD is ‘Cat.4’ device, STM32L15/6xxE is ‘Cat.5’ device, and to the
STM32L15/6xxD, STM32L15/6xxE datasheets. Documents are available for download from
