FE1.1S
USB 2.0 HIGH SPEED 4-PORT HUB CONTROLLER
_______________________Data Sheet_______________________
INTRODUCTION
The FE1.1s is a highly integrated, high quality,
high performance, low power consumption, yet
low cost solution for USB 2.0 High Speed 4-Port
Hub.
It adopts Single Transaction Translator (STT)
architecture to be more cost effective. Six,
instead of two, non-periodic transaction buffers
are used to minimize potential traffic jamming.
The whole design is based on state-machine-
control to reduce the response delay time; no
micro controller is used in this chip.
To guarantee high quality, the whole chip is
covered by Test Scan Chain – even on the high
speed (480MHz) modules, so that all the logic
components could be fully tested before shipping.
Special Build-In-Self-Test mode is designed to
exercise all high, full, and low speed Analog
Front End (AFE) components on the packaging
and testing stages as well.
Low power consumption is achieved by using
0.18μm technology and comprehensive
power/clock control mechanism. Most part of the
chip will not be clocked unless needed.

Note 1 – LED Status Indicators and External Serial EEPROM Interface
The FE1.1s supports up to 5 LED for status indication with DRV, LED1, and LED2 pins, as shown by
Fig. 4. For each Downstream Facing Port, one LED (Green) is provided to indicate that the attached
device of the corresponding port is enabled or not. The fifth LED (Red) shows the Active (On) or
Suspend (Off) status of the Hub itself. The FE1.1s can be configured by an external serial EEPROM
via LED1 and TESTJ pins. The EEPROM is checked and loaded each time after chip reset.

0x1F Check Sum The 8-bit sum of all value from 0x00 to 0x1E.
The first two bytes are the check code from the existence of EEPROM, their value must be 0x1A40.
Any other value would cause the EEPROM loading mechanism of FE1.1s to conclude that the contents
of this EEPROM is unusable, and use the default value instead.
The last byte, 0x1F, is a checksum made up of the sum of all value from 0x00 to 0x1E. The number
must match to render the content of the EEPROM usable. Otherwise, the loading mechanism of FE1.1s
would discard the value from EEPROM and use default value instead.
