Does NXP MCU got DFSDM peripheral like STM32 ?

[Isabella5529]

Are there any nxp mcu with a DFSDM (Digital Filter for Sigma-Delta Modulator) or equivalent to interface and filter PDM signal in hardware?

Hi,

I suppose that you want to get a mcu which supports digital PDM microphone. If it is the case, I think that the LPC family has DMIC module, which supports PDM.
