Hi Jagan,

Please confirm whether you are asking for any specific SHARC processor. Is it possible to share more about your application.

In ADSP-SC59x processor, you can use "Pulse Density Modulation (PDM) Microphone Interface" to connect external MIC. Please refer the "PDM Interface"(Page No: 951/3782) chapter for more for information.
