MSP430FG438 16 位超低功耗 MCU，具有 48KB 闪存、2KB RAM、12 位 ADC、双 DAC、DMA、3 个 OPAMP 和 128 段 LCD
The Texas Instruments MSP430 Family of ultralow power microcontrollers consist 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 attribute to maximum code efficiency. The digitally controlled oscillator (DCO) allows wake-up form low-power modes to active mode in less than 6µs.
The MSP430FG43x series are microcontroller configurations with two 16-bit timers, a high performance 12-bit A/D converter, dual 12-bit D/A converter, three configurable operational amplifiers, one universal synchronous/asynchronous communication interface (USART), DMA, 48 I/O pins, and a liquid crystal display (LCD) driver
