To whom it may concern,
Considering Vdpum=1.8V and Vdpu1~Vdpu4 are either 3.3V or 1.8V, what's the requirement for Vcc voltage? Based on the datasheet that Vpass should be less than 1.8V in this case, does that mean Vcc shouls be less than 2.7V? Is there any other constraint for this design?
Thanks,
Antony
