Description:

MSP430FR263x / MSP430FR253x Ultra-Low-Power Microcontrollers are FRAM-based ultra-low-power MSP microcontrollers that feature CapTIvate touch technology. These are designed for buttons, sliders, wheels (BSW), and proximity applications. CapTIvate technology provides the highest resolution capacitive-touch solution in the market with high reliability and noise immunity at the lowest power. CapTIvate technology supports concurrent self-capacitance and mutual-capacitance electrodes on the same design for maximum flexibility. Using the CapTIvate Design Center, engineers can quickly develop BSW applications with an easy-to-use GUI.
