PRELIMINARY PRODUCT BRIEF

μPD720102

USB 2.0 HOST CONTROLLER

The μPD720102 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 μPD720102 is integrated 2 host controller cores with PCI interface and USB 2.0 transceivers into a

single chip.

FEATURES

•

Compliant with universal serial bus specification revision

•

32-bit 33 MHz host interface compliant with PCI

specification release 2.2

2.0 (data rate: 1.5/12/480 Mbps)

Compliant with open host controller interface

specification for USB rev 1.0a

•

Supports PCI mobile design guide revision 1.1

Supports PCI-bus power management interface

specification release 1.1

Compliant with enhanced host controller interface

specification for USB revision 1.0

•

PCI bus bus-master access

PCI multi-function device consists of one OHCI host

controller core for full-/low-speed signaling and one

EHCI host controller core for high-speed signaling

Root hub with 3 (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

Supports 3.3 V PCI

System clock is generated by 30 MHz crystal or 48 MHz

clock input.

•

Operational registers direct-mapped to PCI memory

space

•

Native driver support in various operating sysytem.

3.3 V single power supply, 1.5 V internal operating

voltage from on chip regulator

•

Supports hyper-speed transfer mode using HSMODE

signal. Transfer rate is 1.5 times higher than existing

host controllers

•

On chip Rs and Rpd resistors for USB signals

APPLICATION

• CardBus card and PCI board for PC

• Digital TV, DVD recorder, and STB

• Digital audio system

• Printer, copy and fax machine

• Router, NAS (Network Attached Storage)
