The

Interface Specification for full-/low-speed signaling and Intel's Enhanced Host Controller Interface Specification for

high-speed signaling and works up to 480 Mbps. The

interface and USB2.0 transceivers into a single chip.

Detailed function descriptions are provided in the following user’s manual. Be sure to read the manual before designing.

FEATURES

• Compliant with Universal Serial Bus Specification Revision 2.0 (Data rate 1.5/12/480 Mbps)

• Compliant with Open Host Controller Interface Specification for USB Rev 1.0a

• Compliant with Enhanced Host Controller Interface Specification for USB Rev 1.0

• PCI multi-function device consists of two OHCI host controller cores for full-/low-speed signaling and one EHCI host

controller core for high-speed signaling.

• Root hub with 5 (max.) downstream facing ports which are shared by OHCI and EHCI host controller cores.

• All downstream facing ports can handle high-speed (480 Mbps), full-speed (12 Mbps), and low-speed (1.5 Mbps)

transaction.

• Configurable number of downstream facing ports (2 to 5)

• 32-bit 33 MHz host interface compliant to PCI Specification release 2.2

• Supports PCI Mobile Design Guide Revision 1.1

• Supports PCI-Bus Power Management Interface Specification release 1.1

• PCI bus bus-master access

• System clock is generated by 30 MHz X’tal or 48 MHz clock input.

− System clock frequency should be set from system software (BIOS) or EEPROM. More detail, see

User’s Manual.

• Operational registers direct-mapped to PCI memory space

• Legacy support for all downstream facing ports. Legacy support features allow easy migration for motherboard

implementation.

• 3.3 V power supply, PCI signal pins have 5 V tolerant circuit.
