The Texas Instruments ultra-low power MSP430? microcontroller 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 5?μs.

The MSP430F51x2 series are microcontroller configurations with two 16-bit high-resolution timers, universal serial communication interfaces (USCI_A0 and USCI_B0), 32-bit hardware multiplier, a high performance 10-bit analog-to-digital (A/D) converter, on-chip comparator, three-channel DMA, 5-V tolerant I/Os, and up to 29?I/O pins.
