Description

The MSP430FR267x is an ultra-low-power MSP430™ microcontroller for capacitive touch sensing that featureCapTIvate touch technologyfor buttons, slides, wheel and proximity applications. MSP430 MCUs with CapTIvate technology provide the most integrated and autonomous capacitive-touch solution in the market with high reliability and noise immunity at the lowest power. TI’s capacitive touch technology supports concurrent self-capacitance and mutual-capacitance electrodes on the same design for maximum flexibility. 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 your design started quickly. Development kits include theMSP-CAPT-FR2633 CapTIvate Technology Development Kit. 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 are also supported by extensive online collateral, such as ourhousekeeping example series,MSP Academy training, and online support through theTI E2E™ support forums. The TI MSP430 family of low-power microcontrollers consists of devices with 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).
