Description: Designing A Low Cost USB-PS/2 Combination Interface Mouse
with the Cypress Semiconductor CY7C63723 enCoRe USB
Microcontroller
Introduction
The Universal Serial Bus (USB) is an industry
standard serial interface between a computer and
peripherals such as a mouse, joystick, keyboard,
UPS, etc. This application note describes how a
cost-effective combination USB-PS/2 mouse can
be built using the Cypress Semiconductor
CY7C63723 USB microcontroller. The document
starts with the basic operations of a computer
mouse peripheral followed by an introduction to
the CY7C63723 USB microcontroller. A
schematic of the CY7C63723 USB
microcontroller to the optics and buttons of a
standard mouse can be found in the Hardware
Implementation Section. The software section of
this application note describes the architecture of
the firmware required to implement the USB
and PS/2 mouse functions. This application note
assumes that the reader is familiar with the
CY7C63723 USB micr
