USB 2.0 Device Controller with ULPI interface
DUSB2-ULPI bridge to APB, AHB, and AXI bus, it 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, as well as 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),
- 480 Mb/s “High Speed” (HS).
The design is technology independent and thus can be implemented in variety of process technologies. This core strictly conforms to the USB Specification v2.0 and ULPI v2.0. It is delivered with a fully automated test bench and a complete set of tests, allowing easy package validation at each stage of SoC design flow.
ALL DCD’S IP CORES ARE TECHNOLOGY INDEPENDENT WHICH MEANS THAT THEY ARE 100% COMPATIBLE WITH ALL FPGA & ASIC VENDORS E.G.
