Feature Multi-Touch Capacitive Touch Controller PCT1322QK: Multi-Touch Capacitive Touch Controller General Description PCT1322QK is a low-power, 2-touch Capacitive-Touch controller to provide a touchpad system with high report rate, high accuracy, and low latency. It is using a mutualcapacitance measurement technology to sense capacitance changes and to detect multiple touch points simultaneously to realize as a touch system. It is designed to meet the increasingly demanding needs for multitouch performance application. This is a Pix Art’s Poco Touch solution that supports touch detection, gesture interpretation and motion tracking for trackpad and touch pad in HID, mobile and wearable applications. An Interrupt flag from the touch controller signals the host to read the touch reports. I2C is used for serial munication between the PCT1322QK and the host. A large set of registers facilitates features and performance optimization....
