    [SOLVED] CY8CMBR3106S - Getting No ACK

    robbe.van.assche

      Hey,

         

      I have a PCB with the CY8CMBR3106S on. It's a low volume product (500-1k).

         

      But, when i try to talk to the sensor via I2C, the sensor does not respond.

         

      I understand it is in low power mode, but it never wakes up.

         

      It has 1V8 on it's internal regulator and 3V3 on the VDD.

         

      Seperate decoupling caps close to the VDD / CMOD.

         

      Any solutions? I am searching almost 2 days already..
      Would be a shame to not use this chip this far in my design process..
