Question
UCPD VDD and VDDIO2 on STM32G0B1CEU6N
We are using STM32G0B1CEU6N to implement two PD sink ports. USB is not used. We also need IOs with 1.8V and 3.3V levels. Device datasheet states in Table 81 that UCPD requires VDD to be 3.0-3.6V in sink applications. All UCPD CC pins are in VDDIO2 bank. Does UCPD require VDD to be 3.0V or is it really powered from VDDIO2? What voltage level is required on VDDIO2 to support UCPD CC pins?
