ETC FT8U100AX

Future Technology Devices International Ltd.
FT8U100AX USB Compound Hub Controller
Overview
The FT8U100AX USB hub and peripheral controller is specifically designed for implementing a wide
range of USB hub devices including those with embedded functions such as Ir remote controls, IrDA
and wireless communications, monitor controllers etc.. The device includes the USB repeater and hub
controller blocks together with an embedded EMCU micro-controller and many associated peripheral
blocks to perform the embedded functions. Included is support for legacy devices such as PS/2
keyboards and mice, serial and parallel ports and a master/slave Access Bus ( I2C ) controller for
monitor applications. Firmware is in a low-cost external OTP ROM which allows maximum flexibility
for many different product configurations.
With its 7 downstream ports and support for self powered or bus powered power sources and gang
switched or per-port switched USB power management the FT8U100AX USB hub represents a very
wide ranging and flexible solution for most USB hub requirements whilst its low external part count
keeps manufacturer’s product cost to a minimum.
The FT8U100AX’s wide ranging capabilities make it the ideal choice for application areas such as
stand-alone hub boxes ( self or bus powered ) with value added functions such as Ir multi-media
wireless remote and game-pad controllers, USB monitor-hubs with extended Ir capabilities, USB
keyboard hubs etc. The FT8U100AX uses 3.3 volt process technology which lowers power
consumption and reduces electrical noise emissions thus making it easier for products using this device
to conform to FCC and CE emission requirements.
Features
•
Integral high speed USB interface (UPI)
and hub repeater / controller block
compliant with USB Specification 1.0
•
Master / Slave Access Bus ( I2C )
controller for USB Monitor-HUB
applications.
•
Integral EMCU micro-controller with
external OTP ROM, 256 byte data
memory, timer and parallel I/O ports.
•
Low power USB Suspend / Resume mode
•
3.3 volt technology provides consistent
performance over the entire operating
voltage spectrum of USB, and eliminates
USB drop and droop voltage supply
problems
•
Reduced electrical noise emission through
the use of 3.3v technology helps products
to conform with FCC and CE electrical
interference regulations.
•
Low component count even for
applications with embedded functions.
•
100 pin PQFP package
•
Up to 7 USB downstream ports and 1
upstream USB port.
•
Support for self powered and bus powered
device configurations.
•
Gang switched or Per-Port switched power
management support.
•
Support for IrDA standard SIR and CIR
wireless communication protocols.
•
Support for FT-Ir multimedia remote
control, Ir game-pad and Monitor Remote
controller using associated FT8IR24 Ir
transmitter device.
