1.0 Introduction
1.1 Description
The AU9432 R2 is an integrated USB keyboard and 2 port hub controller chip. The
AU9432 R2 has a built-in default keyboard matrix, so that it can be directly
connected to an 18 x 8 keyboard matrix. The keyboard matrix can be customized
via an optional external 1024-byte serial EEPROM. Downstream ports can be used
to connect various USB peripheral devices, such as USB printers, modems, scanners,
cameras, mice, and joysticks to the system without adding external glue logic. It
also supports multimedia volume control, CD/DVD Play/Pause, Stop, Eject, Mute
and general purpose shortcut keys such as Internet, email and help.
This single chip integration makes the AU9432 R2 the most cost effective
hub/keyboard solution available in the market.

Support with the Universal Serial Bus Specification, version 1.1
USB hub design is compliant with Universal Serial Bus Hub Specification,
revision 1.1
USB keyboard design is compliant with USB Device Class Definition for Human
Interface Devices (HID), Firmware Specification, version 1.1
Single chip integration of USB keyboard, hub, ACPI and multimedia control
functions
Integrated USB hub supports two bus-powered downstream ports
Patent-pending, table-driven SCANTABLE technology for easy customization
to different keyboard matrix up to 18x8.
Support rotary encoder for multimedia volume control
Support CD/DVD Play/Pause, Fast Forward, Rewind, Stop, Eject, Mute (up to 24
keys)
Additional general purpose keys for internet, email, help…shortcuts, up to 16
keys.
Additional 2 general purpose LEDs
Support ACPI compliant suspend/shutdown key
Built-in 3.3v voltage regulator allows single +5V operating voltage drawing
directly from USB bus. This results in reduced overall system cost.
Optional gang-powered control pin for downstream port.
Runs at 12Mhz frequency
Available in 64-pin LQFP package.

2.0 Application Block Diagram
The AU9432 R2 is a single chip which integrates USB keyboard and hub functionality.
The upstream port is connected to the USB system. The downstream ports can be
used for a mouse and joystick. The multimedia function keys are designed to
support volume control, CD/DVD, Play/Pause, Stop, Eject, Mute and
general-purpose shortcut keys for one key internet, email and help.

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 the AC coupling capacitor, Cs, is much larger than C1 and C2.

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.

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 stress devices by sudden application of a high
voltage supplied by a 100 PF capacitor through 1.5 Kohm resistance.
Machine-Model stresses devices by sudden application of a high voltage
supplied by a 200 PF 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 5 Volts and ground
respectively.
Testing was started at 5.0 V (Postive) or 0 V(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=0 mA , Icc=100 mA), then the voltage was increased by 0.1
Volts and the pin was tested again.
This procedure was recommended by the JEDEC JC-40.2 CMOS Logic
standardization committee.
Notes:
1. DUT: Device Under Test.
2. PUT: Pin Under Test.
