MSP430F438 MSP430F43x 混合信号微处理器

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
