USB 2.0 Device Controller

USB2DEV is a highly configurable USB 2.0 device Controller core. It can be easily integrated into ASIC as well as FPGA. The PBUS & SBUS interface allows the core to be integrated with any other applications, which requires USB 2.0 interface. The controller architecture is carefully tailored for high throughput, low latency, better reliability, and low power consumption. The controller's simple, configurable and layered architecture is independent of application logic, PHY designs, implementation tools and, most importantly, the target technology. The hardware configurable feature such as number of endpoints allow the core to be used by multiple applications which can share the USB bus bandwidth among them through SBUS interface.
