The TI MSP430™ family of ultra-low-power
microcontrollers consists of several devices featuring different sets of peripherals targeted for
various applications. The architecture, combined with five low-power modes, is optimized to achieve
extended battery life in portable measurement applications. The device 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 device to wake up from low-power modes to active
mode in 3 µs (typical).
The MSP430F533x devices are microcontrollers with an
integrated 3.3-V LDO, a high-performance 12-bit ADC, a comparator, two USCIs, a hardware
multiplier, DMA, four 16-bit timers, an RTC module with alarm capabilities, and up to 74 I/O
