混合信号微控制器 MIXED SIGNAL MICROCONTROLLER
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.
