说明

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 6µs.

The MSP430F43x series are microcontroller configurations with two 16-bit timers, a high performance 12-bit A/D converter, one universal synchronous/asynchronous communication interface (USART),DMA, 48 I/O pins, and a liquid crystal display (LCD) driver.
