USB 2.0 Device Controller with ULPI interface

Overview

The DUSB2-ULPI is a hardware implementation of a full/high-speed peripheral controller that interfaces to an ULPI bus transceiver. The DUSB2-ULPI contains a USB PID and address recognition logic, state machines to handle USB packets and transactions, endpoints number recognition logic and endpoints FIFO control logic. The DUSB2-ULPI is designed to support 12 Mb/s "Full Speed" (FS) and 480 Mb/s "High Speed" (HS) serial data transmission rates. The design is technology independent and thus can be implemented in a variety of process technologies. This core strictly conforms to the USB Specification v 2.0 and ULPI v2.0. It is delivered with fully automated test bench and complete set of tests, allowing easy package validation at each stage of SoC design flow.
