Features

General Description

HT82M98A is a 3D mouse controller especially de-

signed for USB and PS/2 applications. The HT82M98A

can support the USB Standard Request as well as HID

Class Request version 1.1. It is compatible with

Microsoft Intelli 3D PS/2 mouse. The X/Y axis photo in-

put with built-in Holtek s special dynamic photo-input re-

sistor and Z axis can support two kinds of scroller input,
