MSP430FW425IPMR

混合信号微控制器 MIXED SIGNAL MICROCONTROLLER

DESCRIPON

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 the device to wake up from low-power modes to active mode in less than 6 µs.
