1.0 Introduction
1.1 Description
The AU9410 is a single chip integrated USB keyboard, ACPI and multimedia function
controller chip. It supports the 19 x 8 keyboard matrix. Each key can be individually
programmed for any USB usage page and usage code, including standard key code, ACPI and
multimedia usage…etc.
Separated ACPI key is another special feature offered by AU9410. There is one pin dedicated
for all-in-one ACPI function, and one additional scan line to support 8 “Desktop” page keys.
The USB descriptors and keyboard matrix can be customized via an optional external 24C08
EEPROM, or directly select the internal 4 different models from internal ROM. This feature
makes customization of new projects cost-effective and efficient by only adding an external
EEPROM while still using the same mass production chip.
To minimize BOM cost, the AU9410 integrated all other components typically founded in an
USB keyboard, it also eliminate external crystal. This single chip integration makes the
AU9410 the most cost effective USB keyboard solution available in the market.

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 HumanBody –Model (HBM) and Machine-Model (MM), according to MIL_STD 883 and EIAJ
IC_121 respectively.
n Human-Body-Model stress devices by sudden application of a high voltage supplied
by a 100 PF capacitor through 1.5 Kohm resistance.
n 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
n Zap Interval : 1 second
n Number of Zaps : 3 positive and 3 negative at room temperature
n Critera : I-V Curve Tracing

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.
