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. 1.2 Features • • • • • • • • • • • • • • • Support 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. Page 6 of 28 AU9432 Multimedia USB Keyboard Hub V1.00W Official Release_ Public 2.0 Application Block Diagram The AU9432 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.

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.
