USB EZ-PD™ Type-C Forum Discussions

Hi,
We're using CYPD5225 notebook template project and have configured our solution as a source only.
Display port alt modes and USB 2.0 work fine.

For some reason SuperSpeed USB 3.X only devices are recognized correctly only in one orientation. When cable is flipped they are enumerated as USB 2.0 devices.
When we plug any Alt Mode enabled device firmware framework calls function mux_ctrl_set_cfg with correct polarity and mux_select_t is correctly given. Code configures then our board Muxes accordingly. However it looks that when a SuperSpeed device is plugged this function is not called at all or it's called with the polarity argument always set 0. I can't be sure because I've not ever been able to run debugger succesfully.

If mux_ctrl_set_cfg is not called for SuperSpeed only device then where and when I should configure the mux? How do I know polarity in this case?

Firmware base version is 3.4.0.2559.

Hello

Regarding CCG3PA. I want to supply power from the VBUS-IN-DISCHARGE terminal. Is there a problem with inserting a bypass capacitor in this terminal?

If possible, is there a recommended capacity?

Also, if it is not possible, I would like to know the reason.

Best Regards

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.

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!
