GL650USB General Description
The GLI650USB is a 5 port USB hub with 1 upstream port and 4 downstream ports. It uses an 8-bit RISC-like uC to encode/decode the host commands. The GL650USB is designed mainly for stand-alone hub and can also be integrated in PC mo therboard or a ny other devices to support USB hub function. The GL650USB can switch between selfpower and bus-power automatically without re-plug in. The GL650USB can be configured as individual mode or ganged mode for the power management of downstream port devices. To prevent from abnormal current consumption of downstream port devices, the GL650USB supplies power enable flags by reading the over-current flags. The GL650USB supports smart traffic indication through the LED lighting. The higher data traffic flows through one port, the higher frequency of that port's LED blinks. To minimize the power consumption, the GL650USB will turn LED off and stop the clock when they are suspended.
GL650USB Maximum Ratings
Maximum ratings are the extreme limits to which the GL652USB can be exposed without permanently damaging it. The GL652USB contains circuitry to protect the inputs against damage from high static voltages; however, do not apply voltages higher than those shown in the table. Keep VIN and VOUT within the range GND (VIN or V OUT) VCC. Connect unused inputs to the appropriate voltage level, either GND or VDD.

GL651USB General Description
The GL651USB is an USB keyboard hub with 1 upstream port and 2 downstream ports. It integrates USB keyboard and hub in a single chip to add extra value to traditional keyboard and lower its total cost. The GL651USB uses an 8-bit RISC-like uC to encode/decode the host commands and to decode the keyboard matrix data. Its 8 generalpurpose I/O(GPIO) pins and the uC-based structure make the implementation of customization very easy. The GL651USB supports 20 drive pins to meet the diversity of keyboard matrix. Besides, 5 GPIO pins support the LED driving, 3 for keyboard and 2 for hub. Hence vendors can decide whether or not to enable the hub LED function easily. For giving more design flexibility, the power supply of GL651USB can be switched automatically: self-power or bus-power. In the same way, vendors can pullup/pulldown the SELF pin to support only self/bus power if they have cost issue. The GL651USB can be configured as ganged/individual mode for hub functions by strapping through pullup/p ulldown the SUSPND pin. To prevent from abnormal current consumption of downstream port devices, the GL651USB supplies power enable flags by reading the over-current flags. By hub LED, The GL651USB also supports smart traffic indication, i.e., the higher data traffic flows through one port, the higher frequency of that port's LED blinks. In order to minimize the power consumption, the GL651USB will turn LED off and stop the clock automatically when it is suspended.
The GL651USB is the most featured and flexible product for those venders who are looking for "USB Keyboard with Hub" solution. Besides, vendors can easily modify their board circuits to meet their own requirement if they have product differentiation or cost issues. Further more, if vendor has the requirement of saving their package cost, COB component also can be supplied by request.
