Description
Embedded Characteristics
The USB Host Port (UHP) interfaces the USB with the host application. It handles Open HCI
protocol (Open Host Controller Interface) as well as USB v2.0 Full-speed and Low-speed
protocols.
The USB Host Port integrates a root hub and transceivers on downstream ports. It provides sev-
eral high-speed half-duplex serial communication ports at a baud rate of 12 Mbit/s. Up to 127
USB devices (printer, camera, mouse, keyboard, disk, etc.) and the USB hub can be connected
to the USB host in the USB “tiered star” topology.
The USB Host Port controller is fully compliant with the OpenHCI specification. The USB Host
Port User Interface (registers description) can be found in the Open HCI Rev 1.0 Specification
available on http://h18000.www1.hp.com/productinfo/development/openhci.html. The standard
OHCI USB stack driver can be easily ported to ATMEL’s architecture in the same way all exist-
ing class drivers run without hardware specialization.
This means that all standard class devices are automatically detected and available to the user
application. As an example, integrating an HID (Human Interface Device) class driver provides a
plug & play feature for all USB keyboards and mouses.
• Compliance with Open HCI Rev 1.0 Specification
• Compliance with USB V2.0 Full-speed and Low-speed Specification
• Supports both Low-Speed 1.5 Mbps and Full-speed 12 Mbps devices
• Root hub integrated with two downstream USB ports in the 217-LFBGA package
• Two embedded USB transceivers
• Supports power management
• Operates as a master on the Matrix
