1. General Description Description Description Description
The MX8733 chip is a low cost single chip optical mouse solution used to implement a
non-mechanical tracking engine for computer mice. It is based on optical navigation technology with
USB/PS2 combo MCU bundled. Which measures changes in position by optically acquiring sequential
surface images(frames) and mathematically determining the direction and magnitude of movement.
The single chip optical mouse sensor provides a complete and compact mouse solution, There are no
moving parts, and precision optical alignment is not required, few outside components use and
facilitate high volume assembly. It is a true crystal-less and ultra low cost solution.
