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

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 40ips.
2. All currents were measured on an ST Reference
Design Mouse supplied with 1.8V at maximum
exposure and include LED and RF stage.
