Description
The MSP430FR25x2 is a family of ultra-low-power MSP430™ microcontrollers (MCUs) for capacitive touch sensing that feature CapTIvate™ touch technology for 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.
