Application note

STM32L1xx

ultralow power features overview

Introduction

The STM32L1xx product line belongs to the STMicroelectronics ultralow power

packages.

Both microcontroller families are based on the ST's proprietary 130 nm ultralow leakage

process and have many analog and digital peripherals in common, which eases the

transition from one architecture to the other and offers users the opportunity to capitalize on

the knowledge acquired on one platform.

This application note describes the key low power features of the STM32L1xx family and

explains their benefits for applications where energy consumption is a major concern.

Important note: This document is not intended to replace STM32L1xx datasheets. All values

given in this document are for guidance only. Please refer to the related datasheet to get

guaranteed values and up-to-date characterization data.
