Description

The VT5366 has been designed for pin to pin

compatibilty

with

the

and

is

STMicroelectronics first generally available chip

for use in all optical mice applications (USB/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 operates over a wide range of

illuminant wavelengths. For devices operating at

approximatively 850 nm (IR LED or VCSEL), the

on-die

automatic

exposure

controller

(AEC)

compensates

for

the

change

in

sensitivity

compared

to

640nm

(red

LED).

Motion

performance can be improved by increasing the

current supplied to the navigation LED.
