General Description
HT82M21A is a 3D mouse controller especially de-
signed for USB and PS/2 applications. The HT82M21A
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 Z-axis can support
two kinds of scroller input, namely; optomechanical and
mechanical. It requires minimal external components to
implement 3D USB plus PS/2 optical mouse. It can be
briefly described as a Holtek 8-bit MCU with an on-chip
USBinterfacelogic.TheUSBisspecifiedbythe
Univer-
sal Serial Bus Specification V1.1.
