The Texas InstrumentsMSP430 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 portablemeasurement 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.

TheMSP430FG47x is amicrocontroller configurationwith two 16-bit timers, a basic timerwith a real-time clock, a high performance 16-bit sigma-delta A/D converter, dual 12-bit D/A converters, two configurable operational amplifiers, two universal serial communication interface, 48 I/O pins, and a liquid crystal display driver.

Typical applications for this device include analog and digital sensor systems, digital motor control, remote controls, thermostats, digital timers, hand-held meters, etc.
