2 FUNCTIONAL OVERVIEW
The GL603USB is a 8-bits RISC-like high performance microcontroller with a built-in 1.5Mbps SIE and
transceiver. The microcontroller features 33 instructions optimized for USB and PS/2 mouse. There are 64
bytes on-chip RAM and 2.75K x 14 program ROM incorporated into the microcontroller. Because the
GL603USB build in a clock generator circuit, it can accepts a 6 MHz ceramic resonator or a crystal as its
clock source. The clock generator can generate 12 MHz clock for micro-controller to sense mouse tracking
signal. The clock is only enabled when bit 1 of PORTCON1 register is cleared. In default firmware, it
indicates the controller is running on PS/2 mouse mode. The sampling rate of mouse tracking signal can be
up to 100 us in USB mode and 80 us in PS/2 mode. The micro-controller features 13 general purpose I/Os
(GPIOs). 8 GPIO pins build in 4 bits ADC for photo-sensor input to remove the expensive process of
matching LED and photo-sensor. Additionally, 2 GPIO pins are strong enough to drive LEDs. The other 3
GPIO pins is used for mouse buttons by default firmware. Beside the 13 GPIO pins, another 2 GPIO pins
combined with USB D+/D- functions can be used as DATA and CLK in PS/2 mode. Legacy USB cable
can be used for mouse in USB mode and an USB to PS/2 converter is required in PS/2 mode. All GPIO
ports feature low EMI emissions as a result of improved output drivers with slew-rate control.
