Texas Instruments' MSP430FR2676 ultra-low-power MSP430 MCUs are designed for capacitive-touch sensing and feature CapTIvate touch technology for buttons, slides, wheels, and proximity applications. The MSP430 MCUs with CapTIvate technology provide an ultra-integrated and autonomous capacitive-touch solution with high reliability and noise immunity at ultra-low power. TI’s capacitive touch technology supports concurrent self-capacitance and mutual-capacitance electrodes on the same design for maximum flexibility. The MSP430 MCUs with CapTIvate technology operate through thick glass, plastic enclosures, metal, and wood with operation in harsh environments including wet, greasy, and dirty environments.
TI capacitive-touch sensing MSP430 MCUs are supported by an extensive hardware and software ecosystem with reference designs and code examples to get the user's design started quickly. Development kits include the MSP-CAPT-FR2633 CapTIvate Technology Development Kit. TI provides free software including the CapTIvate Design Center where users can quickly develop applications with an easy-to-use GUI and MSP430Ware™ software and comprehensive documentation with the CapTIvate Technology Guide.
The MSP430 family of low-power MCUs consist of different sets of peripherals targeted for various applications. The architecture combined with extensive low-power modes is optimized to achieve extended battery life in portable measurement applications. The MCU features a powerful 16-bit RISC CPU, 16-bit registers, and constant generators that contribute to maximum code efficiency. The digitally controlled oscillator (DCO) allows the MCU to wake up from low-power modes to active-mode in less than 10 µs (typical).
