Application note

Maximizing power efficiency using STM32F411xx Batch Acquisition

Mode (BAM)

Introduction

devices are the entry level to the High-performance F4 Series and offer the best balance of

dynamic power consumption and processing performance, while achieving outstanding low-

power consumption in Run, Sleep and Stop modes.

With the new Batch Acquisition Mode (BAM) which allows optimizing power consumption for

data batching, the STM32F411xx microcontrollers brings the Dynamic Efficiency to a new

level.

This application note guides you to achieve the expected power consumptions on

STM32F411xx microcontrollers through an application case. It also provides an example of

how to implement the BAM.

This application note is provided with STSW-STM32154 firmware package.
