TLV320AIC36EVM-K: Digital microphone : onboard or external ?

Jagrit Arora

Part Number: TLV320AIC36EVM-K

Hello,

Does TLV320AIC36EVM-K also have an onboard digital microphone ? Or does it just have input pins to connect an external digital microphone ?

Thanks and Best Regards,

Jagrit,

There are no on board digital microphones, the Digital microphones can be connected using the GPIO headers shown below:

Jagrit,

Yes, you could use that header as well. Each of the GPIOs is configurable as a MIC_CLK_out or a PDM_IN.

P6 is only a 2x2 header though. no digital mics on the PCB.
