Other Parts Discussed in Thread: DS90UB947-Q1
Hi,
I'm using DS90UB927Q-Q1 with VDDIO = 1.8 V.
Is it ok to connect the (2.2 kΩ) pullups of the I2C bus to 1.8 V as well?
I'm asking this because the datasheet states on page 4 for the SCL and SDA pins:
"Must have an external pullup to VDD33."
Chapter 6.7 Electrical Characteristics: DC and AC Serial Control Bus, on page 10, would suggest that 1.8 V pullups should work just fine. Am I correct?
