Overview
DATA SHEET MOS INTEGRATED CIRCUIT µPD720101 USB2.
0 HOST CONTROLLER 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.
Detailed function descriptions are provided in the following user’s manual.
Be sure to read the manual before designing.
µPD720101 User’s Manual: S16336E 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.
