This document describes the steps and key points for migrating microcontroller applications from STM32F1 series to STM32L1 series. It covers hardware migration, peripheral migration, and firmware migration. This document is intended for users familiar with the STM32 microcontroller family.
This application note assists designers in migrating microcontroller applications from the STM32F1 series to the STM32L1 series. It addresses the need to replace microcontrollers due to growing product requirements, cost reduction objectives, or the need to shrink PCB area. The document focuses on the transition from general-purpose STM32F1xxx devices to the ultra-low-power STM32L1 family.
This document helps designers migrate applications from STM32F1 devices to STM32L1 devices.
Revision 2 added support for medium+ and high-density STM32L1xxx devices.
The Flash memory density ranges between 64 and 128 Kbyte.
