INTRODUCTION 1
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.

INTRODUCTION 2
• 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
