Application note
Power consumption optimization with STM32F3xx microcontrollers
Introduction
This application note describes how to optimize the power consumption of an application
based on STM32F3xx microcontrollers.
Reducing power consumption while performing complex real-time applications presents a
major challenge for the recent embedded applications.
This application note is splitted in two main parts:
• The first part gives an overview of low-power design integrated features and
techniques to reduce the power consumption.
• The second part describes a use case (a smart motor control application) that
highlights the power efficiency of STM32F3xx microcontrollers for the competitive
applications of the embedded system market.
This application note is provided with the STSW-STM32036 software package that contains
an example of STM32F3xx microcontroller low-power application. This application is based
on the USART, DMA, timer, comparator, RTC peripherals using STM32F3xx microcontroller
low-power modes and features.
