1.0 Introduction
1.1 Description
The AU9462 is an integrated low cost single chip USB keyboard controller with
2-port hub. It supports the 19 x 8 keyboard matrix. Each key can be individually
programmed for standard key code, ACPI or multimedia usage. It also supports
combinational key definitions in the standard 19 x 8 key matrix.
Separated ACPI key is a special feature offered by AU9462. There is one pin
dedicated for all-in-one ACPI function. Fn key function is designed to enable
selection of alternative matrix for small size keyboard application.
The USB descriptors and keyboard matrix can be customized via an optional
external 24C08 EEPROM, or directly select the internal ROMs for 8 different model
keyboards. This feature makes customization of new projects cost-effective and
efficient by adding an optional external EEPROM while still using the same chip for
mass production. Alcor also provides utility program to simplify EEPROM contents
programming.
The USB downstream ports can be used to connect various USB peripheral devices,
such as USB printer, modem, scanner, camera, mouse and joystick to the system
without adding external glue logic. Multimedia and shortcut keys can support
volume control, CD/DVD Play/Pause, Stop, Eject, Mute and general purpose
shortcut keys such as Internet, e-mail and help.

5.4 Crystal Oscillator Circuit Setup for
Characterization
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.

5.5 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 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
Test circuit & condition
Zap Interval : 1 second
Number of Zaps : 3 positive and 3 negative at room temperature

5.6 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 (Positive) 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.
