GENERAL DESCRIPTION The W81282F is a highly integrated USB keyboard with 4 port hub controller chip. The W81282F has a built-in 21X8 default keyboard matrix, so that it can be directly connected to keyboard with multi-media function matrix. The keyboard matrix, vendor ID, and device ID can be easily customized from an optional EEPROM or modify firmware to meet any customers' requirement. The 4 USB down-stream port can be used to connect various USB peripheral devices, such as printer, modem, speaker, camera, mice, and joystick, to system without any external glue logics. The W81282F use 12MHz clock input with internal PLL to eliminate EMI effect. The W81282F also built-in ESD/EFT protection circuit so it can pass ESD/EFT test without any external glue logics. 2.
