The EM84520 Scrolling Mouse Controller is specially designed to control serial mouse or PS/2 mouse device. This single chip can interface three key-switches and 4 X-Y photo-couples plus Z-axis directly to RS-232C or 8042 controller. There are four types Z-axis inputs used to implement scrolling mouse functionality. FEATURES Using 50kΩ ±1% resistor for RC os.
Using 50kΩ ±1% resistor for RC oscillation. Compatible with legacy PS/2 mouse. Compatible with Microsoft serial scrolling mouse. Compatible with Microsoft PS/2 scrolling mouse. Serial or PS/2 port auto-detect. 100 bytes PnP ID code could be filled by code layer. Built-in noise immunity circuit. The sampiling rate of motion detector is up to 65KHz. Built-in three zener diodes : one in VDD to VSS, two in RTS to VDD. CMOS push-pull RXD output. Built-in current comparator for photo-couples input. Built-in three step dynamic input impedance. Three key-switches and four photo-couples inputs. RTS deb.
