Hi, you proficient friends, please help me ! I am designing a PCB system for audio product, and I plan to choose the samsung's SC2410 chip as the MPU, it's usb port is 1.1, but we need support high speed (480M) usb2.0 , so I have to add a usb2.0 chip, which may be ali m5635, or philips isp1561, or CY7C68013 or others, I do not how to decide usb2.0 chip yet. What still confused me is that how can I combine the SC2410 ,usb2.0 and all other chips,such as Flash,SDRAM or devices as micro disk to work together well. Because SC2410 has no spare address resource for usb2.0 chip, so do I need to use the SDRAM as agency for link usb2.0 with flash or SC2410 or micro disk. and how to write the usb driver for this system. Any friends's advice or a schematic circuit diagram is appreciated very much. I need you guys kind help!
