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.
1.
Speed limitation is due to RF protocol, which is also in line with the USB Low Speed Device.
The VT5365 motion detector can handle up to 40...
