Azoteq IQS266 ProxSense Capacitive Sensor Controller
Azoteq IQS266 ProxSense® Capacitive Sensor Controller is a single self capacitive proximity and 6 channel projected trackpad sensor featuring an internal voltage regulator and reference capacitor (CS). The IQS266 has 6 pins for the connection of sense electrodes, which consist of 1 self electrode, for proximity wake-up, as well as 2 receivers and 3 transmitters, for a 2x3 trackpad. Three pins are used for serial data communication through the I2CTM compatible protocol, including an optional RDY pin.
