1.2 General Description

The FT8U100AX is a 7-Port stand-alone USB hub controller IC with firmware in external OTP ROM for

maximum flexibility and product differentiation. It’s high integration includes an advanced USB 7-Port Hub

controller, EMCU micro-controller core and a variety of embedded peripheral ports allowing a wide variety of

legacy and other peripherals to be connected to and controlled by a USB enabled system through a

FT8U100AX based hub.

The FT8U100AX has power control and over-current detect on each of the 7 downstream ports and

features 2 status LEDs per port providing a useful diagnostic aid for peripherals plugged into the hub ports.

A wide range of pre-tested firmware is available from FTDI including 4 and 7 Port hub solutions with

support for legacy keyboards and mice and RS232 serial peripherals. Legacy keyboards and mice plugged into

the PS/2 ports are translated by the into USB HID 1.0 compliant protocol whilst firmware and Windows ’98

drivers are available for the RS232 serial port function.

A range of tested standard reference designs is available to compliment the firmware and ensure ease

of design and fast time to market.

The FT8U100AXintegrates all the above functions into a single cost effective 100 pin PQFP package,

requiring only external power switches and a few components to complete the design.
