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.
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.
