The PAN3101 is a low cost CMOS-process optical mouse sensor with DSP integration chip that serves as
a non-mechanical motion estimation engine for implementing a computer mouse. It is based on new
optical navigation technology, which measures changes in position by optically acquiring sequential
surface images (frames) and mathematically determining the direction and magnitude of movement. The
sensor is in a 8pin optical package. The current X and Y information are available in registers accessed
via a serial port.
