USB EZ-PD™ Type-C Forum Discussions
Use EZ-PD Configuration Utility to check the configuration file efficiency is too low during mass production. I want to develop a software to check it automatically, but I didn't find the API documents. Please help me, thanks!
Hi, I am interested to use the CCG2 in my design for USB-C PD. Even though the documents say it supports the USB-C PD functions, but I didn't see it any where about CRC generation and validation. I wonder does the hardware provide this feature, or do I need to write my own FW to generate the 32-bit CRC while sending, and validate the CRC from the incoming message.Show Less
I create a project base on CCG3 Dongle project and then I can't start debug.
someone said I need disable Bootloadable, I tried to disable it , then I get below building error

I have a CYPD3125 Consumer only project and I would like to implement Current sense for the Consumer path. I understand that this is possible with firmware changes, however I require some guidance on how to get there.
I have based my Project on a modified CYPD3125 Notebook SDK example.
With initial discussion over mail with CY community I come to know that CCGx SDK will not support for CCG1 and hence for any firmware update one need to seek CY Local FAE.
Can it be highligted when user need to look for firmware update? say list of features that can be controlled from firmware.
Looking for India(Bangalore) Region mail id.
Thank you,Show Less
Please advise what is the maximum Tc specification of CCG3PA (24QFN)?
Data sheet explains Tj_max = 120 deg-C, Ta_max = 105 deg-C and Tja=19.98 deg/W but it doesn't mean maximum power consumption is 0.75W (= 15/19.98), right?
What is the specification for maximum power consumption? And what is the Tc_max specification under this condition?
I'm unable to make UART serial communication with CX3. I tried UartLpRegMode example. When I single stepped through my code with a J-link segger debugger, I realized that rxTxByte is always zero and apiRetStatus is 69. I'm not getting anything on the serial terminal when I set to the baud rate I configured in the program. Tried putting some CyU3PDebugPrint statements, but nothing is getting printed. Even, after configuring the UART. Tried shorting TXD and RXD pins to see any loopback, but no improvements. Even manual values are not getting printed. I'm not sure, whether I'm running properly and testing. Any suggestions would be greatly helpful. Thanks for helping !Show Less
This is Satyajit from Intel.
We are using CCG2 eMarker (CYPD2103-20FNXIT) in our design. It’s similar to Passive eMarked cable.
We want to use this design to carry 10Gbps Thunderbolt signals. Our requirements is,
- eMarker should advertise cable properties as 10Gbps speed support only.
We downloaded CCG2 firmware from,
As firmware is available only in binary format, we don’t know if it supports 10Gbps only speed as mentioned above.
Can you point me to the right firmware? If it’s not readily available, can you share updated firmware where cable property (speed) is limited to 10Gbps?
Thanks and regards,
I downloaded CCG3PA SDK, and installed it on my environment.
I found the firmware for CYPD3174 and CYPD3175 devices, and I think the firmware is for reference design.
CYPD3174 FW - 45W EZ-PD™ CCG3PA USB-C Notebook Power Adapter Solution using MPS
CYPD3175 FW - EZ-PD™ CCG3PA USB-C Mobile Power Adapter Solution using Power Integrations
Is this correct?

We are developing a direct attach peripheral (no intermediate cable) that requires 20V@3.5A. How can we negotiate the higher power level (without an EMCA cable)?Show Less
