• ADuCM331 "Invalid ROM Table" Error


    I'm working on a design with ADuCM331. When I use ARM Ulink Plus SWD interface to download program to my prototype I get the error Invalid ROM Table.

    I tried to use lower clock speed and changed the setting but no lucky. There are some solutions…

  • Can't write value to flash(ADuCM331)

    Can't write value at 0x7FC location again in ADuCM331.

    At first, 0x7FC location can be written with 0x00000000, 0x00000000. And the value can be cheked by the debug.

    And nexttime, I try to rewrite value 0xffffffff, 0x16400000 at 0x7FC location. but…

  • Can't run my application in ADuCM331

    Can't run my application in ADuCM331.

    Using Attached example file in IAR, after compile the source without warning and error, downloading to target board(exactly EVAL-ADUCM331QSPZ). And the target worked well.

    And then, in attached example file I…

  • RE: Not able to connect debugger to AduCM331.


    I have replicated the scenario you described.

    You need to connet GPIO5 to GND and perform a power reset.

    This should allow you to regain access to the device.



  • RE: Difference between ADuCM331WFS and ADuCM300W

    Hi Bruce,

    the ADuCM300 is a re-spin of the ADuCM331.
    The idea is to have a part available with no reference to intelligent battery sensing to appeal to a different market.


  • About ADuCM33x ADC Offset/Gain Calibration

    Hi Community,

    I'm working with ADuCM331 for current measurement application but my code for ADC channel self offset and gain calibration looks not good.

    According to the datasheet it looks that if a self offset calibration command(ADCMDE = 0x4) is…
