1.0 Introduction
Description
The AU9432 R2 is an integrated USB keyboard and 2 port hub controller chip. The AU9432 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 can be 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 AU9432 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.

NOTES: 1. Stresses beyond those listed 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 150C. 3. The input and output voltage ratings may be exceeded if the input and output clamp current ratings are observed.

5.9 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 (Postive) 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.
