Migrating from STM32L4 and STM32L4+ to STM32L5 Series microcontrollers - Application note
■Designers of STM32 microcontroller applications must be able to easily replace one microcontroller type by another in the same product family or products from a different family.
■Migrating an application to a different microcontroller is often needed when product requirements grow, putting extra demands on memory size, or increasing the number of I/Os. The cost reduction objectives may also be an argument to switch to smaller components and shrink the PCB area.
■This application note analyzes the steps required to migrate from an existing design based on the STM32L4 or STM32L4+Series, to an application using the STM32L5 Series.
■This document lists the full set of features available for the STM32L4 and STM32L4+ Series, and the equivalent features on theSTM32L5 Series, and provides a guideline on both hardware and peripheral migration.
■To fully benefit from this application note, the user must be familiar with the STM32 microcontroller family.
