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 1 • • • • • • • • 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 INTRODUCTION 2 2.0 Application Block Diagram The AU9462 is a single chip that integrates USB keyboard, ACPI and multimedia control functionalities. The multimedia function keys are designed to support a full range of hotkeys such as CD/DVD, Play/Pause, Stop, Eject, Mute and general purpose shortcut keys for one key Internet, E-mail, Help and etc. USB Upstream Port USB Downstream Port PC with USB Host Controller Rotary encoder, volume control USB Keyboard Hub USB Mouse USB Scanner USB Downstream Port APPLICATION BLOCK DIAGRAM 3 APPLICATION BLOCK DIAGRAM 4 3.0 Pin Assignment SCROLL_LOCK NUM_LOCK 62 GNDK BIN EEPENABLE CAPS_LOCK AIN ACPIKEYN FNKEYN E2P_CLK E2P_DATA ROMSEL3 SCAN_C8 VCCK LED1 LED2 64 63 61 60 59 58 57 56 55 54 53 52 51 50 49 48 47 46 45 44 43 42 41 40 39 38 37 36 XTAL_1 XTAL_2 GNDA VCCA NC DP2_PWROUT 1 2 3 4 5 6 7 8 9 10 11 12 13 SCAN_C7 SCAN_C6 SCAN_C5 SCAN_C4 SCAN_C3 SCAN_C2 SCAN_C1 SCAN_R19 SCAN_R18 SCAN_R17 SCAN_R16 SCAN_R15 SCAN_R14 SCAN_R13 SCAN_R12 SCAN_R11 NC DP1_PWROUT NC VCC5V NC VCC3V USB_DM USB_DP USB1_DP USB1_DM 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 35 34 33 SCAN_R3 SCAN_R2 NC USB2_DM USB2_DP SCAN_R6 SCAN_R5 SCAN_R4 SCAN_R8 SCAN_R7 SCAN_R10 SCAN_R9 GNDIO NC NC SCAN_R1 PIN ASSIGNMENT 5 Table 3-1.
