INTRODUCTION 1
1.0 Introduction
Description
The AT9322 R2 is an integrated USB keyboard and 2 port hub controller chip. The AT9322
R2 has a built-in default keyboard matrix, so that it can be directly connected to an 18 x 8
keyboard matrix. The keyboard matrix can be customized via an optional external 1024-byte
serial EEPROM. Downstream ports canbe used to connect various USB peripheral devices,
such as USB printers, modems, scanners, cameras, mice, and joysticks to the system without
adding external glue logic. It also supports multimedia volume control, CD/DVD Play/Pause,
Stop, Eject, Mute and general purpose shortcut keys such as Internet, email and help.
This single chip integration makes the AT9322 R2 the most cost effective hub/keyboard
solution available in the market.
Features
?? Fully compliant with the Universal Serial Bus Specification,version 1.1
?? USB hub design is compliant with Universal Serial Bus Hub Specification, revision 1.1
?? USB keyboard design is compliant with USB Device Class Definition for Human
Interface Devices (HID), Firmware Specification, version 1.1
?? Single chip integration of USB keyboard, hub, ACPI and multimedia control functions
?? Integrated USB hub supports two bus-powered downstream ports
?? Patent-pending, table-driven SCANTABLE?technology for easy customization to
different keyboard matrix up to 18x8.
?? Support rotary encoder for multimedia volume control
?? Support CD/DVD Play/Pause, Fast Forward, Rewind, Stop, Eject, Mute (up to 24 keys)
?? Additional general purpose keys for internet, email, help…shortcuts, up to 16 keys.
?? Additional 2 general purpose LEDs
?? Support ACPI compliant suspend/shutdown key
?? Built-in 3.3v voltage regulator allows single +5V operating voltage drawing directly from
USB bus. This results in reduced overall system cost.
?? Optional gang-powered control pin for downstream port.
?? Runs at 12Mhz frequency
?? Available in 64-pin LQFP package.

2.0 Application Block Diagram
The AT9322 R2 is a single chip which integrates USB keyboard and hub functionality. The
upstream port is connected to the USB system. The downstream ports can be used for a mouse
and joystick. The multimedia function keys are designed to support volume control, CD/DVD
Play/Pause, Stop, Eject, Mute and general purpose shortcut keys for one key internet, email
and help.

5.6 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.

NOTES:
1. Stresses beyond thoselisted may cause permanent damage to the device. These are stress ratings
only and functional operation of the device at these or any other conditions beyond those indicated
under "Recommended Operating Conditions" is not implied. Exposure to absolute maximum rated
conditions for extended periods may affect device reliability.
2. The performance capability of a high performance integrated circuit in conjunction with its thermal
environment can create junction temperatures which are detrimental to reliability. The maximum
junction temperature of this integrated circuit should not exceed 150°C.
3. The input and output voltage ratings may be exceeded if the input and output clamp current ratings
are observed.
