Hi,
My electrical design engineer is using the CYPD 3171-24LQXQ IC to control USB C and A ports.
There is a sub-system ARM M0 Processor in that IC - is that ARM available to run a separate
program (non-USB stuff) - or is the ARM used to manage or control the USB functions?
Thank you very much

Hi Al Hopfer,
No, the USB-mini is not handled by CCG3PA. So the necessary part of the firmware itself occupies atleast 90% code space.
I am afraid you will not have enough GPIO's and on chip resources for your implementation.
If you want to check, please download the EZ-PD CCGx Power SDK and try adding your customization in the EZ-PD CCGx Power SDK\CCGx\Firmware\projects\CYPD3171-24LQXQ_pb project and try building it.
If you find it infeasible, I would suggest CCG3/CCG4.
