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.

Resolution

800 (default) / 1600 CPI

Pixel size

30.4 µm

Array size

20*20 pixels

Frame rate

Up to 10,000 frames/second

High speed motion

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.

400CPI - 32ips
