1.0 Introduction
1.1.
Description
The AU9368 is an integrated single chip memory card reader controller specially
designed for notebook, hand-held and other PC peripheral devices, which require
fewer components for small PCB area. It supports a widely used flash memory card
such as CF, MD, SMC, xD Picture Card, MS, MS Pro, MS Duo, SD and MMC. It can be
used as removable storage disks in enormous data exchange applications between
PC and PC or PC and various consumer electronic appliances.
The AU9368 reads digital content saved on memory card that user captured with the
portable device such as notebook, digital camera, MP3 player, PDA and mobile
phone… etc. In addition, AU9368 allows user to transfer information such as data,
graphics, texts or digital images from one electronic device to another quickly and
easily. Furthermore, AU9368 integrates power switch function; manufacturers can
use fewer components in their product design.
With AU9368, user’s experience will be also further enhanced by the Plug-and-Play
nature built into latest operation systems such as Windows 2000/XP and Mac OS X.

7.5 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.

7.6 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.

Zap Interval: 1 second
Number of Zaps: 3 positive and 3 negative at room temperature

7.7 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.
The JEDEC JC-40.2 CMOS Logic standardization committee recommended this
procedure.
Notes:
1. DUT: The device under test.
2. PUT: The pin under test.
