1.0 Introduction
1.1. Description
The AU9254A21 is an integrated single chip USB hub controller designed for the emerging
industry-standard Universal Serial Bus (USB). The AU9254A21 supports four USB
downstream ports. Each downstream port has power switch control, and over-current
sensing.
Single chip integration makes the AU9254A21 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.

The following setup was used to measure the open loop voltage gain for crystal oscillator
circuits. The feedback resistor serves to bias the circuit at its quiescent operating point and

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.

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.
