Thankyou for your answer.
Then, can CCG3PA use for sink controller for all range of PD voltage?
I'm trying to make sink controller that controlled by PC via serial communication.
Could I use internal ARM M-0 core in the CCG3PA as a microcontroller to communicate with PC for PD control?
Yes, CCG3PA can support all range of PD voltage.
Of course you can control CCG3PA via uart. If you are familiar with PSoC Creator, it will be much easier for you to do the coding.
You can start from CCGx Power SDK first:
One more question. where can I find a register map of the CCG3PA?
Is there any reference manual for CCG3PA? I can't find on the product page.
Currently CCG3PA Technical Reference Manual is not released on website. We will need you to sign an NDA with Cypress then we can release the file to you.
