Leveraging the benefits of eUSB 3.0/3.1 Gen 1 device controller, eUSB 3.1 Gen 2 is designed using the Inte®l FPGA built-in 10 Gbps transceiver. It isa 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. Itprovides 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 interface allows to manage the controltransfer using software, provides flexibility, while FIFO interface allows to transfer the data over non-control endpoint ensuring highest throughput.


  • Supports SuperSpeed+ (SSP) and SuperSpeed (SS) modes
  • Uses Intel FPGA Device Transceiver as a PHY layer and thus eliminates need for external PHY for USB 3.1
  • Supports High, Full and Low Speed modes using External USB 2.0 PHY
  • Simple FIFO interface to transfer data over non-control endpoint. Capable to support up to 31 endpoints
  • Supported Device Family : Arria® 10 (Gen2 @10Gbps); Cyclone® 10(Gen2 @10Gbps); CycloneV(Gen1 @5Gbps); ArriaV(Gen1 @5Gbps)

Device Utilization and Performance

For Intel® Arria® 10 (up to Gen 2 10Gbps Interface) uses ~16244 ALM and ~76 M20K Memory. For Intel® Cyclone® 10 (up to Gen 2 10Gbps Interface) uses ~16395 ALM and ~73 M20K Memory. For Cyclone V (up to Gen 1 5Gbps Interface) uses ~5600 ALM and ~63 M10K Memory.For Arria V (up to Gen 1 5Gbps Interface) uses ~5510 ALM and ~66 M10K Memory.
