Dear ST
I am using an STM32f412CEUX(UFQFPN48)
STM32f412CEUX's the PB1( DFSDM_DATAIN0) and PB2(DFSDM1_CKIN0) of STM32f412CEUX is connected digital Microphone
I want to get audio signal through STM32f412CEUX's DFSDM Block
But I can not find DFSDM1_CKOUT pin for Microphone clock at STM32f412CEUX
question
1) Does STM32F412CEUX not support DFSDM Block to obtain audio signal from digital microphone
because DFSDM1_CKOUT pin is not exit at STM32f412CEUX

I am extremely sorry to inform you that the STM32F412 in the package UFQFPN48 has no pin for DFSDM1_CKOUT, so DFSDM cannot be used for digital MEMS microphones. However, CKOUT is available for packages with 64, 100 or 144 pins.
Hope that answers your question?
Regards

I've deliberately stayed with the STM32L4 series because it has a pin for the DFSDM1_CKOUT with the 48 pin packages (STM32L451, STM32L452, STM32L462).
