TI recently announced new MSP430 MCUs with integrated capacitive touch, the MSP430FR2512 and MSP430FR2522, that allow developers 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. These new MSP430 microcontrollers with CapTIvate technology are designed to maintain high robustness and reliability when exposed to electromagnetic disturbances, oil, water and grease.
The MSP430FR2512 and MSP430FR2522 MCUs are International Electrotechnical Commission (IEC) 61000-4-6-certified to suit applications exposed to electromagnetic disturbances, oil, water and grease.
The devices claim five times lower power consumption than the competition and support proximity sensing and touch through glass, plastic and metal overlays.
The MCUs allow users to leverage benefits of capacitive touch and proximity sensing for cost-sensitive applications such as access control panels, cooktops, wireless speakers and power tools.
To speed development with these MCUs and CapTIvate technology, TI offers the new BOOSTXL-CAPKEYPAD BoosterPack plug-in module that is compatible with the CapTIvate programmer board (CAPTIVATE-PGMR) or TI LaunchPad development kits.
Production quantities of the MSP430FR2512 and MSP430FR2522 MCUs are available in a 20-pin very thin quad flat no lead (VQFN) package and a 16-pin thin shrink small outline package (TSSOP) starting at US$0.69 in 1,000-unit quantities.
The CapTIvate BoosterPack plug-in module (BOOSTXL-CAPKEYPAD) is available for US$29.99 through the TI store and authorized distributors.
