MOS INTEGRATED CIRCUIT
µPD720100A
USB2.0 HOST CONTROLLER
The µPD720100A 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 µPD720100A is integrated three 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.
µPD720100A User’s Manual: S15534E
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 0.95
• 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 five (max.) downstream facing ports which are shared by OHCI and EHCI host controller core
• 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)
