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 while enabling excellent navigation control and precision on a wide range of surfaces. Housed in the smallest currently available package (7 mm x 7 mm), 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.
