description

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 6

μs.

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), TBD

I/O pins, and a liquid crystal driver (LCD) with integrated contrast control.

This integrated circuit can be damaged by ESD. Texas Instruments recommends that all integrated circuits be handled with

appropriate precautions. Failure to observe proper handling and installation procedures can cause damage. ESD damage can range

from subtle performance degradation to complete device failure. Precision integrated circuits may be more susceptible to damage

because very small parametric changes could cause the device not to meet its published specifications. These devices have limited

built-in ESD protection.
