Description

The AU9472 R2 is an integrated USB keyboard and 2 port hub controller chip. The AU9472 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 AU9472 R2 the most cost effective hub/keyboard solution available in the market.
