description

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 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.
