GENERAL DESCRIPTION
W81181D, an high integrated 4 port USB hub controller which integrates a microcontroller, implements a medium speed (12 MHz) and slow speed (1.5 MHz) Universal Serial Bus (USB) hub control interface. It supports one upstream, four downstream ports and a serial interface. W81181D can be act as multifunction USB device. For example, the whole system can be designed as an USB HUB plus an USB mouse or an USB HUB plus an IR receiver, and no down stream port be occupied as well as no other component needed.
