Application note
Peripheral interconnections on STM32F401 and STM32F411 lines
Introduction
On top of the highest performance and the lowest power consumption of the STM32F4
family, STM32F401/411 peripherals can communicate autonomously, without any
intervention from the CPU, via a network known as peripheral interconnect matrix.
This STM32F401/411 feature enhances CPU real-time performance while substantially
reducing its energy consumption.
The present document first describes the peripheral interconnect matrix features and then
provides an overview on the peripheral interconnections and on how to configure them
depending on your application. This description is completed by a detailed application
example.
This application note must be read in conjunction with STM32F401 line reference manual
(RM0383) and STM32F411 line reference manual (RM0368). Both documents are available
from http://www.st.com/stm32.
