MSP430F5342IRGZR

The MSP family of ultra-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 microcontroller features a powerful 16-bit RISC CPU, 16-bit registers, and a constant generator that contribute to maximum code efficiency. The digitally controlled oscillator (DCO) allows the microcontroller to wake up from low-power modes to active mode in 3.5 μs (typical). The MSP430F534x MCU configurations feature four 16-bit timers, a high-performance 12-bit ADC, two USCIs, a hardware multiplier, DMA, an RTC module with alarm capabilities, and 38 I/O pins.
