PCT1339 Multi-Touch Capacitive Touch Controller

General Description

PCT1339 is a low-power, 5-touch Cap-Touch controller to

provide a touchpad system with high report rate, high

accuracy, and low latency. The IC uses a mutual-

capacitance

measurement

technology

to

sense

capacitance changes and to detect multiple touch points

simultaneously.

Basing on mutual capacitance sensing technology,

PCT1339 is designed to meet the increasingly demanding

needs for multi-touch performance application. All the

touch detection, gesture interpretation and motion

tracking are handled by PCT1339. An Interrupt flag from

the touch controller signals the host to read the touch

reports. I2C is used for serial communication between the

PCT1339 and the host. A large set of registers facilitates

features and performance optimization. Additional user

enhancements or adjustments complement the system

performance objectives.
