Texas Instruments' 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 devices feature a powerful 16-bit RISC CPU, 16-bit registers, and constant generators that contribute to maximum code efficiency. The device is an ultra-low-power mixed signal microcontroller with a built-in 16-bit timer, four I/O pins, a powerful 16-bit RISC CPU, 16-bit registers, and constant generators that contribute to maximum code efficiency.
