Texas Instruments MSP430FR267x CapTIvate Mixed Signal MCUs are an ultra-low-power MSP430 microcontroller for capacitive touch sensing for slides, buttons, wheel and proximity applications. MSP430 MCUs with CapTIvate technology offers the most integrated and autonomous capacitive-touch solution in the market with excellent reliability and noise immunity at low power. The company’s capacitive touch technology supports concurrent self-capacitance and mutual-capacitance electrodes on the same design for maximum flexibility. The solution operates through plastic enclosures, thick glass, metal, and wood with operation in harsh environments including greasy, wet, and dirty environments.
The family of low-power microcontrollers comprises devices with different sets of peripherals aimed at various applications. The architecture, coupled with extensive low-power modes, is optimised to deliver extended battery life in portable measurement applications. The MCU provides a powerful 16-bit RISC CPU, 16-bit registers, and constant generators that contribute to maximum code efficiency. The DCO enables the MCU to wake up from low-power modes to active mode in less than 10µs (typical).
The solution is ideal for major appliances; intrusion HMI keypads and control panels; electronic smart locks, door keypads, and readers; garage door systems; motorized window blinds; remote controls; personal electronics; wireless speakers and headsets; handheld video game controllers; A/V receivers; white goods; and garden and power tools.
