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.

- Up to 8 input pins for key matrix sense pin
- Up to 5 I/O pins with LED drive capability : 3 for keyboard, 2 for hub
- Up to 8 general purpose I/O pins for customization
● Internal memory
- 80 bytes of RAM
- 3.25K ´ 14 of program ROM
- larger size of ROM makes it possible for customization
● On-chip 3.3v output
- No external regulator required
● Integrated USB transceiver
● 12 MHz external clock
