Overview

Freescale Semiconductor Data Sheet: Technical Data An Energy Efficient Solution by Freescale Document Number: MPR121 Rev.

4, 02/2013 Proximity Capacitive Touch Sensor Controller The MPR121 is the second generation sensor controller following the initial release of the MPR03x series of devices.

Key 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 arra.
