The 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 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 less than 6 µs.
The MSP430FG43x devices are microcontrollers with two 16-bit timers, a high-performance 12-bit ADC, dual 12-bit DACs, three configurable operational amplifiers, one universal synchronous/asynchronous communication interface, DMA, 48 I/O pins, and an LCD driver.
