Usb Ps/2 Mouse Microcontroller

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. By Unkown
