USB EZ-PD Type-C

Hi Team Cypress/Infineon,

Any chances we could see the CCG series go open source anytime soon?

Curious to understand the reasoning behind why all these parts are closed source / hex releases only
I mean, very little risk of taking anything to another platform as the "psoc" running it is fairly unique in it's peripheral-set.

Also, many other PD PHY vendors have full open-source PD stacks including the TCPC abstractions layers.

Hello,

Currently, IFX/Cypress is not going to release PD stack lib source code directly. 

But, IFX/Cypress's SDK is very easy to use, you could implement TCPC based on the SDK directly. 

 

Best Regards,

Lisa

Dear Lisa,

Curious on this decision, what do you see as secret in the PD stack?
i.e. the standard is well known as documented by usb.org

I believe Infineon would sell more CCG's if we had access to the stack.
I really want to utilize CCG-series over other brands, but the closed-binary is a no-go for us.

 

Example,

I want to use either CCG5 or CCG6 with full PPS support, but this is only supported in the old CCG3
if the stack was open, we could port this ourselves.
