Description

The VT5366 has been designed for pin to pin

compatibility with the VT5364(a) and is

STMicroelectronics first generally available chip

for use in all optical mice applications: Wired -

USB (Low and Full Speed) and PS2; Wireless -

27MHz/2.4GHz and BlueTooth. The device has

been designed to provide long battery life whilst

enabling excellent navigation control and

precision on a wide range of surfaces.

Housed in the smallest, currently available,

package (7mmx7mm), the chip is suitable for use

in small form-factor mice demanded by laptop

users. Minimal external circuitry is required

thereby reducing BOM and assembly costs.

The VT5366 sensor will operate over a wide

range of illuminant wavelengths. For devices

operating at approx 850nm (IR LED or VCSEL),

the on-die automatic exposure controller (AEC)

will compensate for the change in sensitivity

compared to 640nm (red LED). Motion

performance can be improved by increasing the

current supplied to the navigation LED.

A specifically designed LED optical system with

integrated light guide and lens is available along

with an aperture piece which clips the package in

place aligning the optics. This has been optimized

for low cost, space saving and ease of assembly

in high volume mouse manufacture. No kapton

tape is required in the assembly process. Please

contact STMicroelectronics for supplier details.
