Proximity Capacitive Touch Sensor Controller
The MPR121 is the second generation sensor controller following the initial release of the MPR03x series of devices. The MPR121 features an increased internal intelligence plus Freescale's second generation capacitance detection engine. Some major enhancements include an increased electrode count, a hardware configurable I2C address, an expanded filtering system with debounce, and completely independent electrodes with built-in autoconfiguration. The device also features a 13th simulated electrode which represents the simultaneous charging of all the electrodes connected together. When used with a touch panel or touch screen array, the 13th simulated electrode allows a greater near proximity detection distance and an increased sensing area.
