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.
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 Intergrated USB full speed transceiver Support for 19 x 8 standard key matrix. An Fn pin to select alternative matrix. Each matrix location is flexible to be used as standard or any report ID & usage page code. Support separate ACPI keys. One pin dedicated for all-in-one ACPI function 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 and LED2. An additional LED2 for suspend special usage which will be turned on in suspend or can be defined by vendors Fn key toggles or selectable based on a configuration bit Extended delay key debounce timing option for any keys defined. USB vendor ID, product ID, and keyboard scan code table can be customized via optional external EEPROM. Contains 8K byte ROM to support 8 different keyboard models Runs at 12 Mhz frequency Integrated dual port power switch to eliminate the requirement of external power switch. Available in 64 pin LQFP package chips or probed for dies COB module

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 Critera : I-V Curve Tracing Table 5.4 ESD Data

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.
