DS90UB928Q-Q1: I2C signal (SCL, SDA)

Guru 29720 points
Part Number: DS90UB928Q-Q1


Hi Team,

The datasheet shows the following about I2C signal (SCL, SDA).



Is it possible to pull-up to another 3.3V power supply that isn't VDD33 of DS90UB928Q-Q1?
I assume another 3.3V power supply is powered up after VDD33 is powered up in this case.

I believe it is possible if there is no possiblity to be Hi-Z but would like to confirm just in case.
The background of the question is my customer's system configuration and power-up sequence.


Best Regards,
Yaita
