Hi
I want to help me that how Cypress low speed device such as CY7C63001 programmed with firmware and if it is possible to read firmware from programmed IC.
Thanks
 

Hi
Does any one know wich eprom program I can use for program Cypress low speed USB controller such as CY7C63000A or CY7C63001A or CY7C63100A or CY7C63101A.
Thank to your help
 

You know, the best trick is to use the CDC model to enumerate as a serial port, this way, you won't need to develop the PC-side driver. but I have encountered something quite strange in this, if you specify the USB endpoint buffer sizes to be 64, Windows XP hangs, and dups! but it works quite fine with 63! any experience on this?!

Added after 4 minutes:

you know, to enumerate as a CDC, you just have to send proper descriptor blocks to the USB host... check the standard, it provides examples for all of device classes, and there is one for CDC..
 

the best way will be to take a look at the application notes provided bt the vendor.
 

yes, it would be best if they DID provide anything! you know, the TI guys thought that just designing and manufacturing the chip might be enough! so they did not provide much of other information that they thought not necessary anyway!

Did you have any experience about CY7c68013 or CY7c68013A Firmware?
Now I try to work with these IC and I don't Know how I must start?
 

Well, I think ATMEL has provided some good starting point with the application example they have provided for the AT89C5131 and AT89C5132... since the USB related hardware interface is provided as separate functions, one can easily migrate the source code to almost all of the USB microcontrollers, infact, this is what I did to write my firmware for TUSB3410...
