The Texas Instruments MSP430 family of ultralow-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 wake-up from low-power modes to active mode in less than 6 μs。
