The USB 2.0 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.
The Arasan USB 2.0 compliant device core is vailable with an AHB/AXI, OCP or custom system bus interface. The USB2.0 device core supports 480 Mbits/s in High Speed (HS) mode and 12 Mbits/s in Full Speed (FS) mode of operation. Arasan provides designers with a comprehensive, silicon-proven configurable digital USB 2.0 Device solution that conforms to the USB 2.0 specification. It is designed to seamlessly integrate into any SoC design for an easy and cost effective solution. The Arasan USB 2.0 IP core supports up to 30 configurable IN/OUT non-control endpoints.
Each non-control endpoint has a controller for supporting interrupt, bulk and isochronous transfers. The dedicated control endpoint 0 handles USB defined command structure for Device Control. The USB 2.0 Device IP includes a multi channel 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 that allows
connection to any USB 2.0 transceiver module.
