Part Number: DS15BR400

Hi

I'm using DS15BR400TSQ WQFN Version.

Because of my mistake, leaved open the pin number 20 and 21.

Only Pin Number 3, 4, 6, 7 are connected to the VDD(3.3V)

Is it still working or i should connect 20 and 21 pin to VDD ??

Thanks In Advance

    Hi Hennessy,

    Device has been characterized with all VDD pins tied to 3.3V supply. I am afraid with pins 20 and 21 not connected to 3.3V operation is unknown or it hasn't been characterized. Further device may not meet data sheet specifications. So please connect these pins to 3.3V supply and do your evaluation.

    Regards,, Nasser
