PCT1336QN: Cap-Touch Controller
General Description
PCT1336QN is a low-power, 5-touch Cap-Touch controller
to provide a touch sensor system with high report rate, high
accuracy, and low latency. It is using a mutual-capacitance
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 multi-touch performance
application. This is a PixArt’s PocoTouch 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 and SPI are used for serial
communication between the PCT1336QN and the host. A
large set of registers facilitates features and performance
optimization. Additional user enhancements or
adjustments complement the system performance
objectives.
