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.
For complete module descriptions, see the MSP430F5xx and MSP430F6xx Family User's Guide.
