USB EZ-PD Type-C

Hi,

Are there any updates to the CCG3PA stack so that the device can be updated via UART or I2C?

it's ok to flash it once via SWD, but on the field we can't rely on SWD nor CC to upgrade the firmware.

Thanks

최대 VBUS 전압이 50V 일 때 문제가 있습니까?

 USB IF 규격 및 인증에 문제가 있는지 알고 싶습니다.

Is a diode required for feeding the VDDD pin from a 5V LDO? There are a few configurations shown in the documentation. The ones where VDDD is externally sourced appear to have Diodes. The CYPD3171 dev kit has a 30V 5A diode. I am hoping that is overkill or, is there something structural in the part that can back feed the VBUS to the VDDD pin? I can’t imagine I would ever need a 5A (Huge package size) diode to feed VDDD so I am looking for some confirmation here.

Will the CYPD3177 communicate on a 1.8V I2C bus?  The datasheet does not specify a voltage range for the HPI, and neither does the HPI specification document.  Reference designs show 3.3V I2C bus.

Planning to use CCG3PA for a power-sink (consumer role) only.
The board has no other power-sources nor batteries at the time of an type-c ac/dc being plugged in.

1.)
Can't find anything in the official CCG3PA datasheet that states what VBUS_P_CTRL's default state is.
Since the regulator for the CCG's VDDD rail will be post the 'consumer fet', it would be great with some input if this cold-booting ("dead battery") state is supported. 

2.)
Let's assume we would have a local power-source, so that VDDD would already be powered with a 3.3V rail.
Are there more details available on how to handle the fact that VDDD is also an output/regulator coming from the CCG3PA once it sees VBUS. I can see a diode in the block-level schematic in the datasheet but some more details would be great.

Thanks
