VT5366 Datasheet, PDF (1/5 Pages) STMicroelectronics – 1.8V Optical mouse sensor

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.
