MOS INTEGRATED CIRCUIT
µPD720110A,720160A
USB2.0 HUB CONTROLLER
The µPD720110A, 720160A are USB 2.0 hub devices 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 all upstream
and downstream ports. The µPD720110A, 720160A work backward compatible either when any one of downstream
ports are connected to an USB 1.1 compliant device, or when the upstream port is connected to a USB 1.1
compliant host.
The µPD720110A includes the default descriptors. The µPD720160A is the same silicon as the µPD720110A,
and it has the Mask ROM option that supports customized string descriptors. By putting descriptors into ROM, the
user's information can be implemented in the chip.
Detailed function descriptions are provided in the following user’s manual. Be sure to read the manual before designing.
