3 Description

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 pins.
