HT82M91A - 3D USB Mouse

Description

HT82M91A is a 3D mouse encoder chip especially designed for USB applications.

The HT82M91A can support the USB Standard Request as well as HID Class Request version 1.0.

It can be briefly described as a Holtek 8-bit mC with an on-chip USB interface logic.

Features

  • Complete Universal Serial Bus specification compatibility Serial Bus Interface Engine (SIE) USB transceiver Supports three buttons (R, M, L) and three axes (X, Y, Z) input Z axis can support two kinds of scroller input (optomechanical and mechanical).
  • Single chip solution especially for USB mouse function Halt function and wake-up feature reduce power consumption Has plug and Play functions Minimal external components 6MHz cryst.
