STM32H562 - application note/out of box example for SAI with PDM mic

[MKout.1]

At the moment, we evaluate feasibility of STM32H562 for our application. Our application is using PDM microphones. However, STM32H562 has SAI interfaces but no DFSDM filters.

Is there any out of box application example /application note for PDM microphone with SAI interface? (multichannel solution for 4 PDMs would be nice, 2 PDMs is a must)

Hello @MKout.1​ and welcome to the Community :)

Currently, there is no available SAI application for STM32H5.

Maybe you can review and get inspired from the SAI application with STM32CubeU5 MCU package:
