USB EZ-PD™ Type-C Forum Discussions

I want to connect CY4531(DFP) and CY4531(UFP) and comunicate VDM custom command.

DFP side send following code. I refered to CCGx_FW_UserGuide.pdf
dpm_pd_command(port, DPM_CMD_SEND_VDM, &cmd_buf, pd_command_cb)

please tell me How to get VDM custom command at UFP?
Do I 'm able to use "dpm_get_info" command?
Please let me know if there is any reference document.

Hi Everyone,

I want to customize CY6611 EZ-USB HX3PD Evaluation board. In addition to USB hub, I want to integrate a small circuit that can be used to operate dynamixel servo. Is it possible to do that ? If yes, can you give some important points that need to be considered for doing the same.

Thanks

I'm having trouble with the CCG3 resetting during startup.  I used a GPIO (pin 28) and oscilloscope to track it down and VDDD (pin 17) drops about 1 V about 3 ms after the call to dpm_start(0) returns.  At this point in time, VDDD is provided by the internal LDO from VBUS (pin 31).  VBUS is 5 V and I don't see any drop.  dpm_start(0) is called in the main function before the task loop.  I added a delay, so nothing else was running in software at this time.

I tried cutting traces until the problem went away and it was VBUS_C_CTRL (pins 29, 30) that caused the problem to go away.  So, it seems like the FET drivers might be part of the problem.

I didn't have any problems until the latest boards we built.  Was there a change in the chip to either the internal LDO or the FET drivers?  Should I be using a different FET?  Any idea what might be the problem?

I'm using a CYPD3120-40LQXI.  My FETs are DMN3018SSD-13.  My schematic is very similar to Figure 15 in the datasheet (002-03288_EX-PD_CCG3).

I have 10 μF on VBUS, 1.2 μF on VDDD.  VDDIO is connected to VDDD.  I have 10 MΩ to ground on pins 29 and 30.

I am trying to open a PSoC Creator project for the CCG3PA and it reports that the CCG3PA is an outdated device.   PSoC Creator 4.4 even lists the CCG3PA in the new features, so I am confused why the program is complaining that the CCG3PA is an outdated device.

Hello.

This is the USB4 cable I purchased.

The cable information of this product was conf irmed using CY4500.

The result is displayed in this message USB_3_1_GEN1_GEN2 instead of USB4.

Why is the cable, which is a USB IF certified product, unable to display the USB4 message on the CY4500 protocol analyzer?

Hello,

Is this an error in the CCG6DF and CCG6SF datasheet (table 5 and table 40)... Operating Ambient Temperature = -40C to +55C?

+55C seems very low!!

Refer to attached datasheet or following link.

https://www.cypress.com/file/500276/download

All other CCG families speficy an operating ambient temperature range of -40C to 85C for Industrial grade (I) and up to 105C for Extended Industrial grade (Q).

Thanks!

Hello.

What does rsvd3 mean?

Does that mean USB4?

Hello!

I have the cy4531 ez-pd ccg3 evaluation kit.
I wanted to know if there is a possibility to use it to work in this way:
To type C I connect a tablet, and to type B I connect a mouse (for example), then when the power supply is connected, the tablet will charge, and when the power supply is disconnected - the mouse will get its power from the tablet battery?

Hello,
I am currently trying to automate the Programming of a CYPD6125 via SWD.
Using the GUI it works perfectly fine.

In the command line it shows "Device is not in ISSP mode" when I try to Start.

I've seen someone had the same problem in this forum, but there was no solution in the thread.

I use following commands for the setup:
GetPorts
OpenPort "MiniProg3/1839CA00030B" "C:/Program Files (x86)/Cypress/Programmer/"
HEX_ReadFile "K:\\PROJEKTE\\USB-C\\Intel_EHL_CCG6_Fw_v2_0_CYPD6125.hex"
SetProtocol 8  //SWD
SetProtocolConnector 0  //5-Pin-Connector
SetAcquireMode “Reset”
SetProtocolClock 152 //1,6MHz
SetPowerVoltage 3.3
PowerOn
DAP_AcquireChip
Erase //Here the Error Shows

The CLI-User-Guide doesn't really give any further information about the behavior.
