USB 3.0 Device Controller

Overview

The USB 3.0 Device IP core is Arasan’s latest development that enables designers in the PC, mobile, consumer and communication markets to bring significant power and performance enhancements to the popular USB standard while offering backwards compatibility with billions of USB-enabled devices currently in the market.

Arasan provides designers with a comprehensive, silicon-proven configurable digital USB 3.0 Device solution that conforms to the latest USB 3.0 specification. Support for both USB 3.0 and USB 2.0 functionality, the IP core provides the greatest flexibility for all applications. The Device IP core is designed to seamlessly integrate into any SoC design for an easy and cost effective solution.

The Arasan USB 3.0 Device provides a dedicated dual simplex, routable packet architecture for USB3.0 and USB 2.0 packet transfers, with a disable option for power savings. The Arasan USB 3.0 IP supports all power management features as well as a dedicated link manager for each downstream port for increased efficiency. It includes a high performance scatter gather DMA that can be configured to access any endpoint through registers. Optionally, it can interface with an external DMA controller.

The Device IP core provides an UTMI/ULPI interface for USB 2.0 support and a PIPE interface for USB 3.0 support. The Arasan USB 3.0 Device IP Core utilizes a flexible system bus architecture that can support AXI, AHB, OCP or any custom system interface needed for existing SoC development. The system bus can also be replaced with a dedicated FIFO interface to reduce bus bandwidth issues. The IP core includes RTL code, test scripts and a test environment for complete design verification.
