1.3 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 extensive 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 devices to wake up from low-
power modes to active mode in 3.5 µs (typical).
