ST UM0555 VT5363 USB Wired Reference Mouse User Manual

ST UM0555 VT5363 USB Wired Reference Mouse

Introduction

The STV-363-R04 is a wired laser low-speed reference mouse developed by EDOM. The reference design consists of the VT5363V032 mouse sensor and the EDOM ML-00036 lens, DA-00075 aperture and 4EVSFMFAZ VCSEL. The mouse can be supplied either from STMicroelectronics or EDOM.
The STMicroelectronics VT5363 sensor is a complete solid state optical tracking engine. This single chip optical mouse sensor provides excellent control and precision, it supports two, three or five button mouse designs with a mechanical scroll wheel encoder. An external EEPROM can be used to implement customer specific USB configurations (PID, VID and descriptor string).
The lens, aperture and VCSEL are designed to work with the VT5363 sensor so that the mouse works accurately on a wide range of surfaces. The design of the reference mouse also ensures high reliability, optical alignment and easy mass production.

This user manual, along with the VT5363 datasheet enable you to evaluate the EDOM STV-363-R04 laser wired reference mouse and assist you in the design of your own VT5363 mouse. Support can be obtained though EDOM (contact details shown in Chapter 3) or through the normal ST regional sales/support groups.

Optics drawings

PCB sectional view

The optics consists of two lenses (incidence and object), the incidence lens ensures that the light going to the sensor is parallel, while the object lens has the magnification of 0.5 x to provide high-speed and accuracy.
The aperture is designed to fit tightly around the sensor package and into the optics, there are also two position poles for aligning the optics to the PCB.

Optics assembly exploded view

The exploded view drawing shows that the aperture, optics and VCSEL are self- aligned when mounted onto the base plate of the mouse.
Care should be taken when handling the optics to avoid scratching the optical surfaces.

VCSEL datasheet

VCSEL binning

There are three separate grades for the VCSEL laser. As part of the manufacturing process the VCSELs are manually sorted into the three grades which means it is a simple process of choosing the right resistor for the grade of laser received.

General

How to use the VT5363 wired mouse

The STV-363-R04 has the usual left, middle, right, forward and back buttons plus ZWheel The cpi can be swapped between 800 (default) and 400. To do this hold down the left and right buttons for 2 seconds.
