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 wake-up from low-power modes to active mode in less than 6 µs. The MSP430FE42x2 devices are microcontroller configurations with two independent 16-bit sigma-delta analog-to-digital (A/D) converters and embedded signal processor core used to measure and calculate single-phase energy in both 2-wire and 3-wire configurations. Also included is a built-in 16-bit timer, 128 LCD segment drive capability, and 14 I/O pins.\n\n Typical applications include 2-wire and 3-wire single-phase metering.
