Leveraging the benefits of eUSB 3.0/3.1 Gen 1 device controller, eUSB 3.1 Gen 2 is designed using the FPGA built-in transceiver. It is a one-stop solution for all USB requirements ranging from USB 3.1 to USB 2.0. It supports SuperSpeed+ (SSP), SuperSpeed (SS), High Speed (HS) and Full Speed (FS) communication modes. The Core architecture allows to use minimal pins from FPGA for USB 3.1 interface with better stability. It provides USB 2.0 backward compatibility using an external USB 2.0 ULPI PHY.
It has been designed to provide simplicity and flexibility along with highest throughput i.e. >7Gbps. Avalon/AXI interface allows to manage the control transfer using software, provides flexibility, while FIFO interface allows to transfer the data over non-control endpoint ensuring highest throughput.
