Description
The PAN3511 is an ultra low cost CMOS process optical mouse sensor single chip with USB interface that embedded internal RC function to replace external resonator and serves as a non-mechanical motion estimation engine for implementing a computer mouse.
CMOS (Complementary Metal-Oxide-Semiconductor) process optical mouse sensors are a type of sensor used in optical mice to detect movement. These sensors are based on CMOS technology, which is widely used in the semiconductor industry for its low power consumption, integration capabilities, and cost-effectiveness.
Features
1. USB interface
2. Single power supply
3. Optical motion estimation technology
4. Complete 2-D motion sensor
5. Accurate motion estimation over a wide range of surfaces
6. High speed motion detection up to 28 inches/sec
7. Power saving mode during times of no movement
8. Supports three buttons (R, M, L) and three axes (X, Y, Z) output
9. Z-axis support mechanical input (Z/2)
10. Internal RC oscillation without external resonator
11. Integrated USB transceiver and 1.5Mbps USB serial interface engine
