DFSDM in STM32F412CEUX

[hongjo]

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

[Peter BENSCH]

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
/Peter

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).
