MSP430FE427 16-Bit Ultra-Low-Power Microcontroller for Energy Meters, 32KB Flash, 1024B RAM

The Texas Instruments MSP430 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 6µs.

The MSP430FE42x series are microcontroller configurations with three independent 16-bit sigma-delta analog-to-digital (A/D) converters and an embedded signal processor core used to measure and calculate single-phase energy in both 2-wire and 3-wire configurations
