smallest package currently available on market
■ Suitable for use with LED and laser light
sources
Description
The VT5365 is the first generally available
complete system on-chip for use in wireless
optical mice. 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 (7mm x 7mm), 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.
Applications
■ Wireless optical mouse for Laptop/Desktop PC
