MSP430F47197IPZR

Product Summary

The MSP430F47197IPZR is a mixed signal microcontroller. The Texas InstrumentsMSP430 family of ultralow－ power microcontrollers consists of several devices featuring different sets of peripherals targeted for various applications. The MSP430F47197IPZR, combined with five low－ power modes, is optimized to achieve extended battery life in portablemeasurement applications. The devices feature 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 6ms. The MSP430F47197IPZR is microcontroller configurations targeted to single－ phase and poly－ phase electricity meters with three, six, or seven 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, four universal serial communication interfaces (USCI), DMA, 68 I/O pins, and a liquid crystal driver (LCD) with integrated contrast control.
