1. generalMx8733d is a highly integrated chip specially designed for optical mouse with USB and PS2 interfaces. It supports USB1.1 protocol, threeGear DPI adjustable: 1000 default /1600 /2000, supporting roller z-axis input. Built in high-precision clock generator, no externalConnected to the crystal oscillator and equipped with few periral components, the optical mouse can achieve exnt anti-interference, high sensitivity, very low power consumption and other performance,And can support simplified production to the greatest extent.2. feature introduction1) Standard 3d4key mouse2) Support key to change DPI (1000 default /1600 /2000)3) Support single channel led to indicate DPI4) Support USB and PS2 interfaces5) 5V power supply6) Crystal free oscillator7) Periral circuit simplification8) Comply with Microsoft WHQL, usb-if test, and compatible with mainstream windows full system operating system9) Sdip12 environmental protection package
