FEATURES
DESCRIPTION
PINNING
PACKAGE
ÿ
ÿ
Supply voltage range 3.0V to 5.5V
Programable detection algorithms for many
different applications
8-Bit microcontroller with 4MHz clockrate
4kByte EEPROM
The IC is an optical sensor which provides a non-mechanical de-
tection of movements. The EEPROM allows a free configuration of
the sensor-structure and the detection algorithms.

The infrared emitting diodes (IRED, signal diodes) and the photo-
diode are placed on a PCB in a required formation. The ability to
detect the motion of an object on the surface depends on chang-
es in the optical path of the reflected signal, changing the relative
light intensity of LED pairs.
