USB hosts hubs transceivers Forum Discussions
can anybody help me about how to communicate with cypress cy7c67300 . i am unable to find respective APIs. actually ths mentioned ic is used on FPGA board ML605 as usb controller. i am inttending to use the host usb port available on the board to communicate data on /from the FPGA and host pc..
regards
Show LessHi,
I want to design 7-port High speed USB hub.
Cypress has only 4-port USB hub at max.
But, using 2 X 4-port USB hub we can implement 7-port, I think.
I have choseen "CY7C65642 - 28LTXC" for this purpose.
I have following requirements.
1) 7 Downstream ports
2) No EPROM
3) NO LEDs
Could you please provide me the schematic diagram as per my requirements.
And also, let me know what are the other things should be taken care during design and implementation.
Thanks,
Raju
Show LessHi
Is there a CY7C67300 developer kit. The one listed is no longer available. I'm just about to commit to using the Viniculum2 devices - but the CY7C67300 has better functionality for me. I need to find a way of testing out the CY7C67300 quickly to see if it will work for me.
thanks
Show LessAre there any application notes or design recommendations for daisy chaining CY7C65630 hubs? For example, connecting four CY7C65630 hubs downstream of a fifth at the board level, making 16 downstream ports available through a single upstream port.
Show LessHave you checked out our latest HX2VL hub based DVKs CY4607 http://www.cypress.com/?rID=55801 and CY4608 http://www.cypress.com/?rID=55802
Show LessHi all,
I'd like to use the CY7C67200 in our design. I saw a linux driver in the mainline.
What is the status of this driver in the mainline kernel ?
Is there a board which support the CY7C67200 in HPI mode ?
I'd like to find an example in order to include the support of the CY7C67200 in my BSP.
Regards

Show LessCypress recently launched our new HX2VL low power HS USB hubs. They are available in 2/4 port configurations as well as Multi/Single TT options. For more information, visit the following page:

Show LessHi,
I'm designing a 4 port USB 2.0 multi TT Hub controller and for which I have selected the "CY7C65642" device.
I have referred the datasheet and have following queries:
[1] CY7C65642 have the option of using the default descriptors to configure the hub with default VID and PID are 0x04B4 and 0x6572. On power up, CY7C65642 has an option to enumerate from the default settings in the mask ROM or from reading an external EEPROM for configuration information.
In my design VID and PID values are not important. Can I go ahead for the design without using EEPROM ?
[2] I do not have requirement of LED indicators and hence have chosen 28 QFN. Now my query is QFN does not support pin strapping and other pin configuration options. Are the default setting enough to make it work as a multi TT 4 downstream USB port ?
[3] Assuming I design without EEPROM, what all programming consideration are to be taken, if any ? Also, any hardware setting to be done while designing ?
Reply ASAP... thanks.
Show LessWe are looking for a way to have the Blaster/Primer or other tool to program a CyPress Hub chip (CY7C65630) on Windows 7 but have not yet successfully. It works fine with Windows XP.
When have the blaster/primer runs on Windows 7, it does not recognize the device; it works fine on XP.
Show LessHi, just a question: can I design a hub board using the 2ports hub CY7C65620-56LTXC chip without the spi eeprom? Any issues to consider about it? Is it really necesssary for a quick and cheap design?
Thanks in advance.
