描述： The μPD720101 complies with the Universal Serial Bus Specification Revision 2.0 and Open Host Controller 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 μPD720101 is integrated 3 host controller cores with PCI interface and USB2.0 transceivers into a single chip. 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 μPD720101 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.
