Description

The Texas Instruments MSP430 family of ultralow power microcontrollers consist 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 attribute to maximum code efficiency. The digitally controlled oscillator (DCO) allows wake-up from low-power modes to active mode in less than 6µs.

The MSP430F47xx series are microcontroller configurations targeted to single phase electricity meters with three or four 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, three universal serial communication interfaces (USCI), 72 I/O pins, and a liquid crystal driver (LCD) with integrated contrast control.
