The maximum cable length supported by the CY7C68003-24LQXIT is 3 meters (10 feet) for full-speed devices and 1 meter (3.3 feet) for low-speed devices, assuming a good quality cable and proper termination.
To implement a custom USB device class with the CY7C68003-24LQXIT, you need to develop a custom firmware that uses the Cypress EZ-USB FX2 API to communicate with the host. You will also need to create a custom device class driver on the host side to interact with your device.
No, the CY7C68003-24LQXIT is not designed to be used as a USB hub. It is a USB peripheral controller that can be used to implement a single USB device function, such as a USB-to-UART bridge or a USB-to-I2C bridge.
The power consumption of the CY7C68003-24LQXIT depends on the operating mode and the clock frequency. In suspend mode, the power consumption is typically around 2mA, while in active mode, it can range from 50mA to 200mA depending on the clock frequency and the device configuration.
You can use the Cypress EZ-USB FX2 Development Kit, which includes a debugger and a programmer, to debug your firmware on the CY7C68003-24LQXIT. You can also use third-party debuggers and programmers that support the CY7C68003-24LQXIT.
