USB EZ-PD™ Type-C Forum Discussions

Hey there,

I'm new to programming microcontrollers, so please bear with me when I ask these questions.

I'm programming the CYPD3171 included on the CY4532 EVK and looking through a code example compatible with the kit. The code example is CYPD3171-24LQXQ_cla01.cydsn for reference. 

I'm having a hard time understanding the kit's guide and the code example's architecture, but is there a way to update the firmware to alter the power output of the USB-C port, or is the power output completely dependent on the device interfaced with said port? I'm using the EVK as a means to test code for another PCB I'm designing for PD applications that uses another CCG3PA chip, but I need to work out the logic involving changing the voltage on the USB-C VBUS line first.

Again, I'm very new to this environment, so please be patient with me in my struggles. I appreciate any feedback or help. 

Hello

Please tell me about the DC characteristics of the I/O of CYPD3171.Please check Table 8 I/O DC specifications.

Q1) Could you please tell me the values of VOH and VOL when VDDD=3.3V?

Q2) In relation to Q1) above, please share a document (ex. characteristic chart) that shows how much the Output Voltage changes depending on the IOH and IOL values.

Best Regards

Hello

Regarding programming FW by SWD with Miniprog3, is it possible to connect two ICs (CCG3PA) in parallel and program different firmware (FW-A = CCG3PA ①, FW-B = CCG3PA ②) to each IC as shown in the attached figure?

Best Regards

Dear all,

May I ask would you be available to communicate regarding the CCG4 Evaluation Kit Switch Matrix PS8740 purchasing availability in Vietnam either in worldwide regarding I can purchase regarding the CCG4 Dual USB - C PCB development?

Please let me know.

Thank you.

Best regards,

Hi,

I currently using CCG4 to connect to EMS using SPI communication. The data is sent from EMS (1) to CCG4 (1) using SPI and then from CCG4 (1) to CCG4 (2) using USB Type-C. Since SPI and USB protocols are different, does the CCG4 provide data conversion or an additional MCU is required?

dear team:

这个ACG1F/CCG5 /CCG6/CCG8在应用在notebook/PC ，有什么比较优势，在这三个系列,谢谢！

We are looking for a solution for Type C USB 3.0 Channel Configuration to be operated as DP ALT(Alternate Mode) with the below 2 cases pf operation. The end application is a device which will be compatible with both

1. Mobile Cell phones with DP support (CASE 1) : For the Phones with DP support we need the USB in DP alt mode(DP signals over SS lines)  to be connected to DP to MIPI driver. 

2. Mobile Cell phones without DP support ( CASE 2): However for non DP phones the USB should act as USB SS Lines and we are using a USB to DP converter and then DP to MIPI. 

We are looking at the USB Type C port controller from Infineon/ Cypress Semiconductors – CYPD3120 , However we want a switchable functionality to support both the above scenario. can this IC support  or give any interrupt to implement this functionality. 

We do not have battery in our device and will not require charging control, so if there is any solution with only CC control for Alt mode DP detection.

Hello 

I have a question on WLC1115 datasheet (002-34241 Rev*B. page#1).

on my understanding, WLC1115 can support USB legacy charging protocol like QC2.0/3.0 and AFC. 

however, as described note on datasheet, "Customer MUST acquire the licensing for QC2.0/3.0 and AFC." 

I would like to understand this sentence. Does it mean customer already should have some license for  QC2.0/3.0 and AFC? if customer don't have a license about that, Does it mean customer MUST get the license about QC2.0/3.0 or AFC? otherwise, customer can't use the QC2.0/3.0 and AFC?

is my understanding correct?

Regards,
Jake

Dear IFX

I want to design USB3.0 to HDMI use CYPD3120, do we still need a DP to HDMI convert chip? if yes could you help provide recommand chip? thanks
