1. 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. W81181D acts as an USB hub controller and a hub repeater at the direction of an internal microcontroller. W81181D controls the traffic among the host, four downstream ports, and the microprocessor. As a hub controller, it can enable/disable ports, send and receive resets, and detect devices of high or low speeds. The W81181D contains three function endpoints and two hub endpoints to allow both USB Control and Interrupt Transfers between the host and microcontroller. W81181D is a compound USB device (hub with embedded function attached) with totally five downstream ports. W81181D can be used as a hub controller in a standalone hub with attached function or a microcontroller based USB device with hub function.

3. USB BLOCK DIAGRAM
The Serial Interface Engine (SIE) controls the USB data flow between the uCs and the USB bus. Port0 is a high speed (HS) transceiver for the upstream data path. The Hub Repeater is the traffic controller which directs the bus data to and from the correct paths. The hub Controller and Function Controller determines what data is to be written to or read from the various FIFOs. The Bus Controller directs the interface between the uC and Hub/Function Controller.
