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 devices feature 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 6µs.
The MSP430F471xx series are microcontroller configurations targeted to single-phase and poly-phase electricity meters with three, six, or seven 16-bit sigma-delta A/D converters. Each channel has a differential input pair and programmable input gain. Also integrated are two 16-bit timers, four universal serial communication interfaces (USCI), DMA, 68 I/O pins, and a liquid crystal driver (LCD) with integrated contrast control.
