Usb 2.0 host controller IP

USB 2.0 High-Speed functionality is supplied by an enhanced host controller implementing the Enhanced Host Controller Interface (EHCI).
Full- and Low-Speed functionality (USB 2.0 and USB 1.1) is supplied by one or more companion controllers implementing the Universal Host Controller Interface (UHCI).
The Port Router supplies the dynamic connection between the host controllers and the USB transceivers.

The USB 2.0 host controller can be configured to support all types of USB transfers – bulk, interrupt and isochronous.
This allows dynamic configuration to support a configurable number of endpoints, interfaces, alternate interfaces and settings.
The USB 2.0 host controller can be configured to support any combination of USB 2.0 interface speeds – HS (480 Mbps), FS (12 Mbps) and LS (1.5 Mbps). Sample combinations are HS, FS, and LS; HS & FS only; FS & LS only; HS only; or FS only.
The USB 2.0 host controller has full support for all low-power features of USB specifications, supporting suspend and remote wakeup and USB 2.0 Link Power Management states (L1, L2).

The USB 2.0 Host IP is a USB 2.0 specification compliant host IP core with an optional AHB, PCI, or custom host interface.
The USB 2.0 Host IP supports 480 Mbit/s in High Speed (HS) mode. 12 Mbit/s in Full Speed (FS) mode, and 1.5 Mbit/s in Low Speed (LS) mode.

The USB 2.0 embedded host controller is designed for flexibility and ease of use; is available with a Software stack; facilitates implementation of a wide variety of applications like PDA to a printer/ hard disk, Camera to a printer / hard disk, etc.,
This design is technology independent and migrating it to any technology is fast and this can be easily bridged to ARM Bus, VCI Bus, etc..

Configuration options to maximize performance and minimize CPU interrupts
Flexible parameters enable easy integration into low and high-latency systems
Transfer- or transaction-based processing of USB data based on system requirements
Configurable data buffering options to fine-tune performance/ area trade-offs

Supports SuperSpeed USB power savings modes, Uniform Power Format (UPF) and dual power rails
Lowers overall system power by design
Configurable data buffering options to fine-tune performance/area trade-offs
Host supports SuperSpeed, High-Speed, Full-Speed, and Low-Speed operation

USB 3.1 Host Controller can be configured to support all types of USB transfers – Bulk, Interrupt and Isochronous.
Allows dynamic configuration to support configurable number of endpoints, interfaces, alternate interfaces and configurations.
USB 3.1 Host Controller can be configured to support any combinations of USB 3.1 interface speeds – SSP (10 Gbps), SS(5 Gbps), HS (480 Mbps), FS(12 Mbps) and LS(1.5 Mbps). Eg combinations are SSP & SS only, SSP & SS & HS only, SSP & SS & HS & FS only, SS Only, SS & HS Only, SS & HS & FS Only, HS & FS Only etc.
USB 3.1 Host Controller has full support for all low power features of the USB Specification supporting Suspend and Remote Wakeup, USB 3.1 Low Power States – U1/U2/U3 and USB 2.0 Link Power Management states – L1, L2.

The USB 2.0 device controller can be configured to support all types of USB transfers – bulk, interrupt and isochronous. While operating in device mode, it can be dynamically configured to support a configurable number of endpoints, interfaces, alternate interfaces, and settings.
The USB 2.0 device controller can be configured to support any combination of USB 2.0 interface speeds – LS (1.5 Mbps), FS (12.0 Mbps), HS (480 Mbps). Sample combinations are LS only, FS only, HS only, LS and FS, and FS and HS.
The USB 2.0 device controller supports all low-power features of USB specifications, including suspend, remote wakeup and Link Power Management states – L1, L2.
The USB 2.0 device controller supports all test modes features, a requisite for obtaining USB-IF certification
