Hi there. It appears that the STM32G0B1KET LQFP32 MCU lacks a UCPD1_CC2 pin. For this reason I have a couple questions.
Solved! Go to Solution.

Dear @NYou.1
A application like STM32G071B-DISCO is clearly an application which can be done with 1 CC line.
UCPD_CC1 line is directly connected to the CC line available in the cable.

You can't assign CC2 to another pin. Since it's not exposed, you can only do things that do not require use of that pin. Seems like you need both CC pins for USB-PD.

So I guess the question becomes: What can we do with the UCPD_CC1 Pin? What is the purpose of only having one?
