MSP430FW425 用于电子流量计的 16 位 RISC 超低功耗微控制器
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 MSP430xW42x series are microcontroller configurations with two built-in 16-bit timers, a comparator, 96 LCD segment drive capability, a scan interface, and 48 I/O pins.
