Application note

STM32F7 Series peripheral interconnections

Introduction

This application note describes how peripherals of the STM32F7 Series microcontrollers

can communicate autonomously without any intervention from the CPU via a network

known as peripheral interconnect matrix.

This new STM32F7 Series feature enhances the CPU real-time performance while

substantially reducing its power consumption.

The present document first describes the peripheral interconnect matrix features and then

provides an overview of the peripheral interconnections and how to configure them

depending of the application. This description is completed by a detailed application

example.

This application note must be read in conjunction with the STM32F75xxx and

STM32F74xxx reference manual (RM0385) available from www.st.com/stm32.

This application note concerns all the devices of the STM32F7 Series.
