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
2.0 (data rate: 1.5/12/480 Mbps)
• Compliant with open host controller interface
specification for USB rev 1.0a
