Hi.
I'm designing a PCB with the PN7150 and a microcontroller.
I have read in the data sheet that the device's I2C interface can work at two logic voltage levels, 1.8V or 3V as logic 1.
If my microcontroller works with 3.3V. My question is:
How do I configure the PN7150 so that the I2C interface works at 3V?
Any comment or suggestion is welcome.
Solved! Go to Solution.

Hi @dominusdrr ,
Maybe there is any misunderstanding? PN7150's VDD(PAD) can be 3.6V at max in case of 3V host supply, and I2C pins 's max input always follows the level on VDD(PAD) without any configuration else. Please kindly refer to the following for details.
Hope that makes sense,
Have a great day,
Kan
