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.
1.2 Features
* * * * * * * * Fully compliant with the Universal Serial Bus Specification, version 1.1 USB keyboard design is compliant with USB Device Class Definition for Human Interface Devices (HID), version 1.1 Built-in 3.3v voltage regulator allows single +5V operating voltage drawing directly from USB bus. Support for 19 x 8 standard key matrix. An Fn pin to selection of alternative matrix. Support separate ACPI keys. One pin dedicated for all-in-one ACPI function and also editable in the 19x8 key matrix Each key can be individually programmed for standard key code, ACPI or multimedia usage Ability to configure the generic LEDs to blink on and off at a rate of 512ms. Additional LED1 (vendor defined) INTRODUCTION 1
* * * * * * * *
An additional LED2 for suspend special usage which will be turned on in suspend or can be defined by vendors Support ACPI compliant suspend/shutdown key Fn key toggles or selectable based on a configuration bit Extended debounce timing is added on the Caps Lock and CD eject key USB vendor ID, product ID, and keyboard scan code table can be customized via optional external EEPROM. Built-in 6 MHz crystal Contains 4K byte ROM to support 4 different keyboard models Available in 48 DIP, 48 LQFP and probed good die. COB module solution is also available

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 Model HBM MM Model Vdd, Vss, I/C Vdd, Vss, I/C S/S 15 15 TARGET 4000V 200V Results Pass Pass

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.
