The component s very efficient implementation makes it suitable for instantiation within a small FPGA. USB2-SOFT does NOT support the following: Host-side protocol, OTG, low-speed, Interrupt and Isochronous endpoints. standard protocol layer including control and bulk endpoints.

Block Diagram to/from USB host USB2 DEVICE PHY ULPI Interface USB2-SOFT UTMI interface USB2 DEVICE SIE ULPI wrapper USB Device User Interface 2* virtual channels FPGA The code is a Serial Interface Engine (SIE) implementing the Device side of the USB 2. The code is compatible with two industry standard interfaces commonly found in USB PHYs: - 12-pin ULPI (example: USB33 from SMSC ) - 22-pin UTMI The code is structured so that the ULPI interface is a wrapper around the UTMI SIE. This FPGA code interfaces with a physical layer transceiver (PHY). The code supports both high-speed (48 Mbits/s) and full-speed (12 Mbits/s) connections.

DEVICE SIE VHDL SOURCE CODE OVERVIEW Overview USB2-SOFT is the VHDL source code to connect an FPGA-based USB device to a USB host.
