USB low-full-high speed peripherals Forum Discussions

Hi, All

In case of SPI communication Master Mode (CPOL=1 / CPHA=1) in CY7C65211A, this is a question.
1. There is no timing specification for CS in the datasheet.
It can be adjusted to MISO or CLK, but if there is a specification that can be checked, please let me know.

2. Output strength is the default value, is it slow rate? Is it fast rate? Please tell us.

Best Regards,

Alex.

Hi,

Using "Cypress USB-Serial Configuration Utility" tool I configured cypress IC CY7C65215-32LTXI from USB-serial to CDC (as a virtual com port) device. I want to change it back to usb-serial, but I cannot see the target under "Cypress USB-Serial Configuration Utility" tool. Could  you help me what I need to get it back as USB-serial device. 

Originally I had it like Figure-1, but now it is as shown in Figure-2

Hello, 

I'm trying to use FX3 as programator for FPGA. First of all, code (AN84868) for project is not available on Infineon web page: Link .

Second when I try program FX3 with FPGA Configuration Utility and pre build FX3 code "ConfigFpgaSlaveFifoSync" with Debug version all works fine. Code is normally uploaded of FX3 device. With FPGA Configuration Utility I can select bitstream. The problem happen if I try to build FX3 code in EZ Suite (no code change). Build is successfully. But when I upload build image (debug or release) with  FPGA Configuration Utility on FX3 device I lose  connection with device. 

FPGA Configuration Utility after programming: 

I'm using Ztex 2.18 board with CYUSB3035-BZXI.  

Does anyone have any idea what is problem? 

I would be gratefully thankful for any advice.  Kind regards.

Is the power domain of the two pins "USBDP" and "USBDM" VCCIO?

Vih and Vil are defined with reference to Vccio. Can USBDP/DM follow these specifications?

I would like to know if it is possible to input up to 3.6V, which is the USB2.0 full speed standard. And I also would like to know if Vih and Vil do not change even if 3.3V is applied to VCC.

Thanks,
Tetsuo

Hello Community,

we are Infineon colleagues and searching for a USB 2.0 to microcontroller UART converter.
Because we want to use it for a customer design board. 
At the moment we are using FTDI TTL-234X-5V-WE. We would prefer to use an Infineon equivalent.

Can you help us out and propose a device?
Maybe a small explanation about the different devices Infineon provides? (Product Selection Guide style...)

best regards,
Cassie

Hello,

We have some question on X-ray result. Why are they had different image? Are they normal? Please see attached photo. 

Thanks

Hello,

I am trying to commit packets using inpktend .

Is there anything in particular that I need to take care of apart from FIFOADR[1:0] pins select. I want to further transfer the received packets to the host.

thanks 

Can additional SPI_Select, chip select lines, be added to a Serial Communication Bus (SCB) interface of CY7C65215/A when in SPI Master mode?

Hello,

I would like to change the VID/PID from the default value to a custom value.

Referring to chapter 3.1 of the Cypress USB-Serial Configuration Utility 2.0 User Guide, I changed the VID/PID in the driver's INF file.

When I tried to manually install the driver in that state, error occurred and I could not install it.

(Error: File hash is missing in the specified catalog file)

How can I use CY7C65211A with custom VID/PID?

Or is there another way to work with custom VID/PID without changing the INF file?

Regards
