Technical note
Migrating from STM32L15/6xRC-A to STM32L15/6xRC and from
STM32L15/6xVC-A to STM32L15/6xVC
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
STM32L15/6xxC-A device to an STM32L15/6xxC device (only for devices in LQFP64 and
LQFP100 packages: STM32L15/6xRC-A and STM32L15/6xVC-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 better understand the information
included in this technical note, the 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 STM32L15/6xxC-A and STM32L15/6xxC are ‘Cat.3’ devices, and to the
STM32L15/6xxC datasheets. Documents are available for download from the company
website at www.st.com/stm32.
