1.3 Description

The MSP430FR263x and MSP430FR253x are FRAM-based ultra-low-power MSP microcontrollers that feature CapTIvate touch technology 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.

The TI MSP family of low-power microcontrollers consists of several devices that feature 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 typically in less than 10 µs.
