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 MSP430FE42x series are microcontroller configurations with three independent 16-bit sigma-delta A/D
converters and embedded signal processor core used to measure and calculate single-phase energy in both
2 and 3 wire configurations. Also included is a built-in 16-bit timer, 128 LCD segment drive capability, and 14
I/O pins.
Typical applications include 2-wire and 3-wire single-phase metering including tamper-resistant meter
implementations.
