VT5366
Feature summary
■ Pin compatible with VT5364
■ Can be used (with external MCU) in all optical
mouse applications
■ Single +1.8V supply
■ Very low power operation, enabling long
battery life
■ CPI programmable up to 3200 (default 800 cpi)
■ Up to 9,600 frames per second
■ Tracking at up to 40 ips
■ I2C Interface
■ On-chip ADC for voltage level reporting
■ Proven, high volume package technology -
smallest package currently available on market
■ Minimal external circuitry
■ Suitable for use with both LED and laser
(VCSEL) light sources
Description
The VT5366 has been designed for pin to pin
compatibilty with the VT5364(a) 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.
1.8V Optical mouse sensor
Data Brief
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.
