Application note
STM32F3 series peripheral interconnect matrix
Introduction
STM32F3 series peripherals communicate autonomously without any intervention from the
CPU, via a network known as peripheral interconnect matrix.
STM32F3 series peripheral interconnect matrix offers multiple benefits:
 autonomous communication between peripherals,
 efficient synchronization between peripherals,
 discarded software latency and minimized GPIOs configuration,
 optimal available pins even with small packages,
 connector usage avoidance leading to optimized PCB design with less dissipated
energy.
The present document first describes the peripheral interconnect matrix, then provides an
overview of the peripheral interconnections and how to configure them with respect to user
applications.
This application note has to be read in conjunction with STM32F3 series datasheets and
