    Dear all,

    There is a specification on FM1808 FRAM chip that "Anytime that the power to
    the device (VDD) drops below 4.0V, the power supply must be taken to 0volts
    (+/-0.1V) for a minimum of 1us before power is restored to the device. It is
    recommended that the VDD pin be actively to ground through a low impedance
    path to ensure reliable power-up operation".

    Please advise on simple circuitry/components recommendation. Thanks!

    Best Regards,

    Soon Heng
