MSP430F412 - 16 位超低功耗微控制器，具有 4kB 闪存、256B RAM、比较器和 96 段 LCD - 超低功耗 - 低功耗MCU - TI公司（Texas Instruments，德州仪器）
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 6 µs.
The MSP430x41x series are microcontroller configurations with one or two built-in 16-bit timers, a comparator, 96 LCD segment drive capability, and 48 I/O pins.
Typical applications include sensor systems that capture analog signals, convert them to digital values, and process the data and transmit them to a host system. The comparator and timer make the configurations ideal for industrial meters, counter applications, handheld meters, etc.
