USB Controllers and Software

USB Controllers play more and more important role in interfacing different electronic devices and subsystems to each other. Numerous standards in different application areas are used and new ones are being developed.

IP cores
USBSS-DEV	The USBSS-DEV IP core logic provides SuperSpeed USB (5 Gbps) function interface that is designed to the 3.0 revision of the USB specification. The USBSS-DEV logic handles bytes transfer autonomously and bridges USB interface to an OCP interface. The USBSS-DEV can be customized and optimized for a specific application.
USBHS-DEV	USB 2.0 Hi-Speed function controller that implements a built-in FIFO-like data port to speed up USB data transfers. The controller supports UTMI and ULPI interfaces for USB PHY, while a generic, AMBA® or PVCI interfaces are available for the CPU.
USBFS-DEV	Low/Full Speed USB 2.0 device controller with an optional DMA engine. The controller supports serial interface for USB PHY as well as generic or AMBA®interface for communication with CPU.
USBHS-OTG-SD	USB 2.0 On-The-Go Dual Role Device controller that supports point to point communication with a single device. Featured interfaces include UTMI+ and ULPI for USB PHY as well as generic, with AMBA® and PVCI for CPU.
USBHS-OTG-MPD	USB 2.0 On-The-Go Dual Role Device controller with Hub support. Built-in USB protocol-aware DMA engine improves overall system performance, while FIFO latency buffers significantly decrease on-chip memory requirements. Featured interfaces include UTMI+, ULPI and AMBA®.
USBHS-HUB	The USBHS-HUB IP core is a feature-rich, configurable USB 2.0 hub controller that has been thoroughly tested for compliance with the 2.0 revision of the USB specification.
Software Stacks
USBHS-HB-OTG Software Stack	Dedicated for Evatronix USBHS-OTG-MPD controller but can support any other IP core of similar functionality that complies with the USB 2.0 specification and On-The-Go supplement to the USB2.0 specification. Implements native support for Hi-Speed USB hubs. By default integrated with eCos operating system for fast application development, with an option to integrate with other operating systems.
USBHS-OTG-MPD Software Stack	A USB 2.0 On-The-Go compliant software layer dedicated to support applications built upon a variety of different microprocessors. Supports USB Host, Peripheral and On-The-Go devices. Designed for systems with or without OS. Layered structure guarantees easy portability to various system architectures and seamless integration with other USB controllers.
USBHS-OTG-SD Software Stack	A USB 2.0 On-The-Go compliant software layer dedicated to support applications built upon a variety of different microprocessors. Enables the direct connection of digital products without a computer host.
USBHS-DEV Software Stack	A usb software stack that supports all Evatronix usb 2.0 controllers. The USBHS-DEV Software Stack is an ideal choice for using USB in an embedded device. Optimized for easy portability and small footprint eliminates substantial development time and costs.
USBHS-51 Software Stack	A USB 2.0 device software stack designed to take full advantage of the 8051 Instruction Set Architecture compliant microcontroller as well as the USB High Speed Controller. It is specifically optimized for small footprint. In general, an application footprint requirement amounts 9 kBytes.
USBFS-51 Software Stack	A USB 1.1/2.0 device software stack designed to take full advantage of the 8051 ISA compliant microcontroller as well as the USB Full Speed Controller. User-friendly API allows a user to build his own 8-bit applications without a detailed knowledge of the USB Full Speed controller hardware. Optimized for small footprint- a minimal memory footprint requires only 6 kBytes.

Our USB cores have been successfully implemented in various ASIC and FPGA technologies.
