introduction 1 1.0 introduction 1.1 description the AU9410 is a single chip integrated usb keyboard, acpi and multimedia function controller chip. it supports the 1 9 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 1 9 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 1 9 x8 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)
introduction 2 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 dip, 48 lqfp and probed good die. cob module solution is also available
application block diagram 3 2.0 a pplication 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. pc with usb host controller usb keyboard usb mouse
