General Description
HT82M98A is a 3D mouse controller especially
designed for USB and PS/2 applications. The
HT82M98A can support the USB Standard Re-
quest as well as HID Class Request version 1.0
draft 4. It is compatible with Microsoft Intelli
3D PS/2 mouse. The X/Y axis photo input with
built-in Holtek¢s special dynamic photo-input
resistor and Z axis can support two kinds of
· _{Single chip solution especially for USB}
mouse function
· _{Halt function and wake-up feature reduce}
power consumption
· _{Plug and Play functions}
· _{Minimal external components}
· _{6MHz crystal oscillator for system clock}
· _{18-pin DIP package}
scroller input, namely; optomechanical and
mechanical. It requires minimal external com-
ponents to implement 3D USB plus PS/2
mouse. It can be briefly described as a Holtek
8-bit mC with an on-chip USB interface logic.
The USB is specified by the Universal Serial
Bus Specification V1.0.
