USB HUB CONTROLLER
1.
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.

Note 1: Measured from 10% to 90% of the data signal.
Note 2: Timing difference between the differential signals.
Note 3: Measured at crossover point of differential data signals.
Note 4: The rising and falling edges should be smoothly transiting(monotonic)
Note 5: Full Speed timing have a 1.5 kW pull-up to 2.8 V on the D+ (DP) data line.
Note 6: Low Speed timing have a 1.5 kW pull-up to 2.8 V on the D- (DM) data line.
Note 7: The maximum load specification is the maximum effective capacitive load allowed that meets
the target hub VBUS droop of 330 mV.
Note 8: All other USB Electrical Characteristics refer to USB spec Rev 1.1 7.3.2 and 7.3.3.
