    Advantages of using an external crystal/oscillator with BMF055

    Hello,

    What are the advantages of using an external crystal or oscillator with the BMF055? Also, were the sensor specifications in the data sheet obtained using the internal oscillator or an external crystal/oscillator?

    Thanks.

    BMF055 is nothing more than a BMG160, BMA280, BMM150 and SAMD20J18RevB microcontroller in a single package.

     

    The choice of using a crystal or not in the microcontroller is up to you, and the benefits of a more accurate clock vary per application.

     

    In the case of sensor fusion, since the gyroscope data is integrated, a more accurate clock leads to a smaller error. the temperature characteristic of the crystals oscillators are also usally far better than the internal RC oscillator over the temperature range, leading to a more stable accuracy over temperature changes.
