描述 Description

AU9410 is a single chip integrated USB keyboard, ACPI and multimedia function controller chip.  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.
