General Description
HT82M22A is a Plug and Play Windows 2000 and
5-button 3D USB+PS/2 Mouse controller. The
HT82M22A 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; mechanical
and optomechanical. It requires minimal external com-
ponents to implement 3D USB plus PS/2 mouse. All its
features combined and make up this versatile Holtek
8-bit MCU with an on-chip USB interface logic. The
USB is specified by the Universal Serial Bus Specifica-
tion V1.1.
