µPD720110A
USB2.0 HUB CONTROLLER
The µPD720110A is an USB 2.0 hub device that comply with the Universal Serial Bus (USB) Specification Revision
2.0 and work up to 480 Mbps. USB2.0 compliant transceivers are integrated for upstream and all downstream ports.
The µPD720110A works backward compatible either when any one of downstream ports is connected to an USB 1.1
compliant device, or when the upstream port is connected to a USB 1.1 compliant host.
Detailed function descriptions are provided in the following user’s manual. Be sure to read the manual before designing.
µPD720110A User’s Manual: S15738E
