Part Number: TIC12400-Q1

Hi experts,

I found the datasheet says that the VDD is for the SPI communications. So the device can normally working if I don't apply VDD power? Is polling mode and wake up still work without VDD?

Thanks

    Frank,

    Yes, these functions will still work without VDD, however, in order to configure polling mode, the SPI registers will need to be written. So if VDD is removed after configuration is complete, then yes this will work, otherwise VDD will have to be supplied at some point.
