PCM2912A: MCU connection

Carlo
Expert 7715 points
Part Number: PCM2912A


Hi team,

Our customer would like to use the PCM2912A with a microcontroller to save recorded files (*.WAV) on a memory card. They would like to read that file on PC through a USB interface. Is it possible to interface the PCM2912A with Atmega 16 microcontroller?


Regards,
Carlo

    Hi Carlo,

    I apologize for the delayed response.

    Is it that there are .wav files present in a PC and through the USB of the PC you like to send the .wav

    files to an external box that has a memory card attached and you like to write the .wav file to this card?

    if this is the case:

    The  PCM2912A is a USB to analog audio converter so the output of the device shall be analog audio.

    In theory you can send this analog audio to the ADC of a Microcontroller to capture the audio. A memory chip attached to SPI can store the values received on the ADC.

    I am not a specialist on the ATMEG16 but you would need 2 ADC 's to capture 20Khz audio and SPI to write the data to a memory.
