Application note
Peripherals interconnections on STM32F405/7xx, STM32F415/7xx,
STM32F42xxx, STM32F43xxx and STM32F446xx
Introduction
This application note describes how peripherals of the microcontrollers listed in Table 1 can
communicate autonomously without any intervention from the CPU via a network known as
Peripherals interconnect matrix.
This feature enhances the CPU real-time performance, while at the same time substantially
reducing its power consumption.
The document begins with the description of the Peripherals interconnect matrix features,
then it provides an overview of the peripherals configuration and their interconnections. An
example is presented and described in detail.
This application note has to be read in conjunction with reference manuals RM0090 and
RM0390, available at www.st.com/stm32.
