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 MSP430F643x 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, an LCD driver, and up to 74 I/O pins.
