It supports the 19 x 8 keyboard matrix. Each key can be individually programmed for any USB usage page and usage code, including standard key code, ACPI and multimedia usage...etc. Separated ACPI key is another special feature offered by AU9410. There is one pin dedicated for all-in-one ACPI function, and one additional scan line to support 8 "Desktop" page keys. The USB descriptors and keyboard matrix can be customized via an optional external 24C08 EEPROM, or directly select the internal 4 different models from internal ROM. This feature makes customization of new projects cost-effective and efficient by only adding an external EEPROM while still using the same mass production chip. To minimize BOM cost, the AU9410 integrated all other components typically founded in an USB keyboard, it also eliminate external crystal. This single chip integration makes the AU9410 the most cost effective USB keyboard solution available in the market. 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. Support for 19 x 8 standard key matrix. An Fn pin to selection of alternative matrix. Support separate ACPI keys. One pin dedicated for all-in-one ACPI function and also editable in the 19x8 key matrix 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 (vendor defined) An additional LED2 for suspend special usage which will be turned on in suspend or can be defined by vendors Support ACPI compliant suspend/shutdown key Fn key toggles or selectable based on a configuration bit Extended debounce timing is added on the Caps Lock and CD eject key USB vendor ID, product ID, and keyboard scan code table can be customized via optional external EEPROM. Built-in 6 MHz crystal Contains 4K byte ROM to support 4 different keyboard models Available in 48 LQFP, 64 LQFP and probed good die. COB module solution is also available Page 6 of 24 AU9410 USB Keyboard Controller V3.00W Official Release_Public 2.0 Application Block Diagram The AU9410 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. Figure 2.1 Au9410 Application Block Diagram U S B M ouse P C w it h U S B H o s t C o n t r o lle r U S B K e y b o a rd Page 7 of 24 AU9410 USB Keyboard Controller V3.00W Official Release_Public 3.0 Pin Assignment 3.1 Pin Assignment Diagram Figure 3.1 Pin Assignment Diagram EEPENABLE 50 USB_DM USB_DP 64 NC SCAN_R1 SCAN_R2 SCAN_R3 SCAN_R4 SCAN_R5 SCAN_R6 SCAN_R7 SCAN_R8 SCAN_R9 SCAN_R10 GNDK VCCK SCAN_R11 NC NC 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 63 62 61 60 59 58 57 56 55 54 53 52 51 GNDIO 49 48 47 46 45 44 NC NC NC LED1 LED2 NUM_LOCK CAPS_LOCK SCROLL_LOCK E2PDATA E2PCLK BIN AIN FNKEYN ACPIKEYN SCAN_C8 NC 43 42 41 40 39 38 37 36 35 34 33 32 NC VCC5V 27 Alcor Micro AU9410 64-PIN LQFP 18 19 20 21 22 23 24 25 26 VCC3V 28 XTAL1 XTAL2 GNDA VCCA RFU NC NC NC NC NC 29 30 31 AU9410 USB Keyboard Controller V3.00W Official Release_Public SCAN_R12 SCAN_R13 SCAN_R14 SCAN_R15 SCAN_R16 SCAN_R17 SCAN_R18 SCAN_R19 SCAN_C1 SCAN_C2 SCAN_C3 SCAN_C4 SCAN_C5 SCAN_C6 SCAN_C7 Page 8 of 24 3.2 Pin Descriptions Table 3.2 64Pin Descriptions I/O Type I/O I/O I/O I/O I/O I/O I/O I/O I/O I/O Power Power I/O Pin No. 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 Pin Name NC SCAN_R1 SCAN_R2 SCAN_R3 SCAN_R4 SCAN_R5 SCAN_R6 SCAN_R7 SCAN_R8 SCAN_R9 SCAN_R10 GNDK VCCK SCAN_R11 NC NC SCAN_R12 SCAN_R13 SCAN_R14 SCAN_R15 SCAN_R16 SCAN_R17 SCAN_R18 SCAN_R19 SCAN_C1 SCAN_C2 SCAN_C3 SCAN_C4 SCAN_C5 SCAN_C6 SCAN_C7 NC NC SCAN_C8 ACPIKEYN FNKEYN AIN Description Row Scan Line 1 Row Scan Line 2 Row Scan Line 3 Row Scan Line 4 Row Scan Line 5 Row Scan Line 6 Row Scan Line 7 Row Scan Line 8 Row Scan Line 9 Row Scan Line 10 Core GND VCC 3.3V for Core power Row Scan Line 11 I/O I/O I/O I/O I/O I/O I/O I/O I I I I I I I Row Scan Line 12 Row Scan Line 13 Row Scan Line 14 Row Scan Line 15 Row Scan Line 16 Row Scan Line 17 Row Scan Line 18 Row Scan Line 19 Column Scan Line Column Scan Line Column Scan Line Column Scan Line Column Scan Line Column Scan Line Column Scan Line 1 2 3 4 5 6 7 I I I I Column Scan Line 8 ACPI Control ("0": Sleep;
