1.3 Description

The TI 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.
