Part Number: TLV320AIC3254


Hi Expert,

I am looking for the checksum and blank area for AIC3254. Do you have idea for it? Thanks!

  • Checksum is for make sure the download firmware.
  • Blank area is for identify the firmware version.

    Hi Jerry, 

    1. No there is no Checksum. You can read the registers back, but only if ADCs and DACs are powered down. take a look at THIS FAQ.

    2. blank area for firmware version?  the Processor you use will always need to program the AIC3254,  the AIC3254 doesn't have any blank space for you to write a firmware version,  but you could do this in the ram where you store your MiniDSP program.  (the miniDSP must be programmed every time the device is powered up)

    best regards,

    Hi Steve,

    but you could do this in the ram where you store your MiniDSP program

    I can't understand it. Is it a component? Could you show me it? Thanks!

    Hi Jerry 

    There is no checksum, and there is no checksum component.  There is a checksum register in our newer devices,  but none of the MiniDSP codecs have this.

    Please check out this thread which also discusses the checksum.  

    best regards
