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
a. To make use of the new battery level function the PCB
and firmware will need to be modified
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.
