MSP430FR2533IRHBT

The MSP430FR2533IRHBT is a mixed signal microcontroller in 32 pin VQFN package. This FRAM based ultra low power MSP microcontroller features CapTIvate touch technology for buttons, sliders, wheels (BSW) & proximity applications. The CapTIvate technology provides highest resolution capacitive touch solution in market with high reliability, noise immunity at lowest power and supports concurrent self capacitance, mutual capacitance electrodes on same design for maximum flexibility. The architecture, combined with extensive low power modes, is optimized to achieve extended battery life in portable measurement applications. The MCU features a powerful 16bit RISC CPU, 16bit 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 10µs. It is used in thermostats, electronic access control, lighting control, electronic door locks & white goods.
