Proximity sensing capability for microcontrollers

Jon Lawson

Bringing capacitive-sensing capabilities to cost-sensitive applications, Texas Instruments has announced an expansion of its MSP430 microcontroller (MCU) family with CapTIvate technology. Developers can use the new MSP430FR2512 and MSP430FR2522 MCUs with integrated capacitive touch to add as many as 16 buttons as well as proximity sensing capability to industrial systems, home automation systems, appliances, power tools, home entertainment, personal audio applications and more.  

The new MCUs offer lower power consumption than the competition, supporting proximity sensing and touch through glass, plastic and metal overlays.
