Freescale Semiconductor MPR03x Proximity Capacitive Touch Sensor Controller
The Freescale Semiconductor MPR03x Proximity Capacitive Touch Sensor Controller is optimized to manage two electrodes with interrupt functionality or three electrodes with the interrupt disabled. The Freescale Semiconductor MPR03x can accommodate a wide range of implementations due to increased sensitivity and a specialized feature set. This Freescale Proximity Capacitive Touch Controller detects the presence of objects without relying on physical contact and can control several applications with one sensor. The Freescale Semiconductor MPR031 demo board allows a user to touch two simple clear buttons and view the LED response using an MPR03x touch sensor controller. The MPR03x evaluation kit allows a user to observe the basic functionality of the device through a couple of demos, including a pinball game and a presentation device.
