I have the same problem like you. I want to use the CY7C68013A controller, but don't know in which way. Have you find some good documents, or have any othher person some suggetions how can I start with this controller.
Please give me some help.
Getting a development kit is the easiest way. Cypress sells one for around 400$. If thats not an option, I came across another company which makes USB kit for cypress -
More USB 2.0 kits -
Some getting started notes -
Basically, you need to write your code and download it to 8051. The popular tools are keil and sdcc(small device C compiler).
