2. FUNCTIONAL OVERVIEW
The GL602USB is an 8-bit RISC-like high performance microcontroller with a built-in 1.5Mbps SIE and
transceiver. The microcontroller features 33 instructions optimized for USB keyboard. There are 96 bytes on-
chip RAM and 4K x 14 bits program ROM incorporated into the micro-controller. The micro-controller features
18 output pins and 8 input pins to make a 18 x 8 key matrix. Additionally, 3 GPIO pins are strong enough to
drive LEDs. 4 GPIO pins can be used by any function, for example, support a PS/2 3D mouse to USB 3D mouse
converter in the default firmware. Legacy USB cable can be used for keyboard in USB mode. All GPIO ports
feature low EMI emissions as a result of improved output drivers with slew-rate control.
