USB EZ-PD™ Type-C Forum Discussions
Hello Cypress-Team,
we are developing a system, which act as a DRP/DRD. Right now we take the CYPD3125-40LQXI. Due to availability issues, I was wondering what is the big difference to the CYPD3126-42FNXIT?
The main features of the device, in terms of USB-C/PD:
- Unit act as a DEVICE: UFP/SINK
- Unit act as POERBANK: SOURCE (Data role is negelctable)
- Unit act as HOST for e.g. USB-Sticks: DFP/SOURCE
- Unit act as HOST, but loaded from peripheral unit: DFP/SINK
Are these settings possible?

when I finished 'EZ-PDProtocolAnalyzerUtility_Windows.exe' installation, we can not run it normally, but the error message is found , refer to the attached Error.jpg file for details.
How can I solve this issue?
Show LessHello,
I am looking for the tool to configure the device CYPD5225.
I have downloaded the software PSoC Creator 4.4, but i was not able to find the component CYPD5225 in this tool !
What is the tool to configure the registers on the CYPD5225 ?
What is the tool to generate the HEX file mention in the document "CCGx (CYPDxxxx) Programming Specifications" Document Number: 002-22328 Rev. *G ?
I have the tool to download the HEX file to the CYPD5225 device but not the tool to generate the HEX file.
Thank you for help,
Best regards,

Show LessHi!
When I copy and compile the standard CYPD3125-40LQXI_notebook.cydsn project from the 3.4 Host SDK both backup_fw and main fw compiles without problem. However, when I change to CYPD3123 (via Device Selector) and change the bootloader to "CYPD3123-40LQXI_usb_boot_3_0_2_900_0_0_0_cu.hex", I get:
ERROR: cannot open linker script file .\cm0g_1.ld: No such file or directory
collect2.exe: error: ld returned 1 exit status
The command 'arm-none-eabi-gcc.exe' failed with exit code '1'.
when building the project. Tried without success:
- Renaming cm0gcc.ld to cm0g_1.ld, but there was no cm0gcc_2.ld in the project folder
- Copy cm0g_1.ld / cm0g_2.ld from the backup_fw projet
Do I need a new USB bootloader file for the 3.4 SDK? Or does the linker-files need to change to fit in the USB booatloader?
Cheers

Show Less当接上cy4500时,EZ-PD analyzer utility 显示 not connected.请问如何debug这个问题
The HX3PD's datasheet says (under "DC Electrical Characteristics" section) that "VBUS for upstream port" voltage must not exceed 5.25V. At the same time VBUS itself can clearly be up to 20V nom. What exactly is VBUS pin (M7 in BGA pacakage) intended for? The pin description section hints that it is a digital input. So I assume that is is kind of VBUS present/not present. Can I interface it to the actual VBUS with a huge resistor hoping that any excessive voltage will be clamped at the pin? See the screenshot attached. Thank you.

In my application CYPD3177 is configured to accept any voltage between 5 and 20V and at least 900 mA current. I also do not use safe_pwr. So in the end the schematics looks like the one in the attachment. It is clear that the part will expect zero volts at VDC_OUT when VBUS_FET_EN is not asserted and will generate FAULT when facing the situation it does not expect.
So here we have fault condition that can not be removed. The question is - how will it affect the part operation? Is there any workaround that does not involve additional FETs and supply ORing controllers?
Thank you.

Dear all,
There are some "VCONN FET Circuit" in the following application diagrams.
What is the purpose of adding the external driving circuit?
I think driving circuits for supplying eMarker are integrated in the CC1/2 functional block. Correct?

Hello,
I'm developing a system that seems to be based on the CY6611 evaluation platform. The block diagram is shown below and here are few words about the development. The system should be configured as sink on the US, so laptop should provide a power for the system. We will need ~50W(20V@2.5A). System should have 6 DS ports, no need for PD on these ports, but only constant 5V, so I believe regular USB load switch should be sufficient for it.
As I sow in one of the post here that US can be configured as sink port, could you confirm that. I also believe I can eliminate usage of U20(NCP81239MNTXG) BB controller.
I would appreciate your opinion of design feasibility. If other evaluation platform(as you you have a lot) are more appropriate I would glad to know about them. Can I submit my design for your verification at the latest stage?

Dear,
I use the MUX_CTRL_I2C Read function in the cypd4236_dock Example code. I use the following MUX_CTRL_I2C api to read it, and even the start signal cannot be generated.
Do you need an init process, or enable those functions?
Best Regards,
Manu
