Part Number: DS90UB954-Q1
Other Parts Discussed in Thread: DS90UB953-Q1,

Hi, Team,

Can DS90UB953-Q1 work with 1.8V VI2C and 3.3V VDDIO?

In our datasheet, it said the VI2C can work with 1.8V and 3.3V, and it looks not relationship with the VDDIO. How does the device know the VI2C voltage which is 1.8V or 3.3V?
