1.0 Introduction
1.1 Description
The AU9254 is an integrated single chip USB hub controller designed for the
emerging industry-standard Universal Serial Bus (USB). The AU9254 supports four
USB downstream ports. Each downstream port has power switch control, and
over-current sensing.
Single chip integration makes the AU9254 the most cost effective stand-alone USB
hub solution available in the market. Downstream ports can be used to connect
various USB peripheral devices, such as USB printers, modems, scanners, cameras,
mice, or joysticks to the system without adding external glue logic.
1.2 Features
•
•
Fully compliant with the Universal Serial Bus Specification, version 1.1.
USB hub design is compliant with Universal Serial Bus Hub Specification,
revision 1.1.
•
•
•
Single chip integrated USB hub controller with embedded proprietary processor.
Supports four bus-powered/self-powered downstream ports.
Built-in 3.3v voltage regulator allows single +5V operating voltage, resulting in
reduced overall system cost.
•
•
Runs at 12Mhz frequency.
28-pin SSOP package, both normal size (body size 209 mil) and smaller size
(body size 150 mil) are available.

NOTES:
1. Stresses beyond those listed may cause permanent damage to the device.
These are stress ratings only and functional operation of the device at these or
any other conditions beyond those indicated under "Recommended Operating
Conditions" is not implied. Exposure to absolute maximum rated conditions for
extended periods may affect device reliability.
2. The performance capability of a high performance integrated circuit in
conjunction with its thermal environment can create junction temperatures
which are detrimental to reliability. The maximum junction temperature of this
integrated circuit should not exceed 150˚C.
3. The input and output voltage ratings may be exceeded if the input and output
clamp current ratings are observed.

5.8 ESD Test Results
Test Description: ESD Testing was performed on a Zapmaster system using the
Human-Body-Model (HBM) and Machine-Model (MM), according to MIL-STD 883 and
EIAJ IC-121 respectively.
•
Human-Body-Model stresses devices by sudden application of a high voltage
supplied by a 100pF capacitor through 1.5k-ohm resistance.
•
Machine-Model stresses devices by sudden application of a high voltage supplied
by a 200pF capacitor through very low (0 ohm) resistance.
Test Circuit & Condition
- Zap Interval: 1 second
- Number of Zaps: 3 positive and 3 negative at room temperature
- Criteria: I-V Curve Tracing

5.9 Latch-Up Test Results
Test Description: Latch-Up testing was performed at room ambient using an
IMCS-4600 system which applies a stepped voltage to one pin per device with all
other pins open except Vdd and Vss which were biased to 5Volts and ground
respectively.
Testing was started at 5.0V (Positive) or 0V (Negative), and the DUT was biased for
0.5 seconds.
If neither the PUT current supply nor the device current supply reached the
predefined limit (DUT=00mA, Icc=100mA), then the voltage was increased by
0.1Volts and the pin was tested again.
This procedure was recommended by the JEDEC JC-40.2 CMOS Logic
standardization committee.
Notes:
1. DUT: The device under test.
2. PUT: The pin under test.
