FUNCTION OVERVIEW
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.

GENERAL DESCRIPTION
The KBD42W11 keyboard controller is programmed to support the IBM® compatible personal computer keyboard serial interface. The keyboard controller receives serial data from the keyboard, checks the parity of the data, translates the scan code, and presents the data to the system as a byte of data in its output buffer. The controller will interrupt the system when data is placed in its output buffer. The byte of data will be sent to the keyboard serially with an odd parity bit automatically inserted. The keyboard is required to acknowLEDge all data transmissions. No transmission should be sent to the keyboard until acknowLEDgment is received for the previous byte sent.

FEATURES
• Supports IBM PC and Compatible System Designs
• Runs Much Faster Than Traditional keyboard controllers
• Host interface Compatible with Traditional keyboard controller
• 6 MHz – 12 MHz Operating Frequency
• Communicates with keyboard Directly
• High-reliability CMOS Technology
• 40 Pin DIP and 44 Pin PLCC Package
