The maximum cable length supported by the CY7C68300C-56PVXC is 3 meters (10 feet) for full-speed devices and 1 meter (3.3 feet) for low-speed devices.
To implement a custom USB device class, you need to create a custom device class driver and modify the device's firmware to support the custom class. You can refer to the Cypress Semiconductor's EZ-USB FX2 Technical Reference Manual for more information.
No, the CY7C68300C-56PVXC is a USB peripheral controller, not a USB host controller. It can only operate as a device, not as a host.
The CY7C68300C-56PVXC supports data transfer rates of up to 480 Mbps (high-speed mode) and 12 Mbps (full-speed mode).
To configure the CY7C68300C-56PVXC for isochronous transfers, you need to set the ISOCHRONOUS bit in the USB registers and configure the endpoint buffers accordingly. Refer to the Cypress Semiconductor's EZ-USB FX2 Technical Reference Manual for more information.
