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 mutualcapacitance 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.
