Description

The MSP430FR25x2 is a family of ultra-low-power MSP430™ microcontrollers (MCUs) for capacitive touch sensing that featureCapTIvate™ touch technologyfor cost-sensitive applications featuring 1 to 16 capacitive buttons or proximity sensing. The MSP430FR25x2 MCUs offer value and performance for industrial applications exposed to electromagnetic disturbances, oil, water, and grease. The devices offer IEC-certified solutions with 5x lower power consumption than competition and support proximity sensing as well as touch through glass, plastic, and metal overlays. TI capacitive touch sensing MSP430 MCUs are supported by an extensive hardware and software ecosystem with reference designs and code examples to get your design started quickly. TheBOOSTXL-CAPKEYPADBoosterPack™ plug-in module can be used with theCAPTIVATE-PGMRprogrammer board (standalone or as part of theMSP-CAPT-FR2633CapTIvate development kit) or with the LaunchPad development kit ecosystem. TI also provides free software including theCapTIvate Design Center, where engineers can quickly develop applications with an easy-to-use GUI andMSP430Ware™ software, and comprehensive documentation with theCapTIvate technology guide. MSP430 MCUs with CapTIvate technology provide the most integrated and autonomous capacitive-touch solutions in the market with high reliability and noise immunity at the lowest power.
