The ability to detect the motion of an object on the surface depends on changes in the optical path of the reflected signal, changing the relative APPLICATION y y y Navigation key for mobile phones, laptop computers and handheld devices Switches, rotation-sliders, proximity-sensors Compact 2-D input device With 4k of EEPROM the customer has enough memory space for even complex applications and an easy to use posibility to protect his know how even in a ASSP. For automotive, industrial and pc applications a version 909.03 with integrated IR diodes and photodiode is available in an ASIC package. plus coming soon DESCRIPTION The IC is an optical sensor which provides a non-mechanical detection of movements. The EEPROM allows a free configuration of the sensor-structure and the detection algorithms. The sensor measures the optical reflections of an object on a cover above the sensor using a system so called HALIOS(R) (High Ambient Light Independent Optical System). HALIOS(R) is high efficient suppressing ambient light and also has an inherent self calibration to eliminate disturbances caused by housing reflections such as scratches.
