MSP430F6434 MSP430F643x 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 3 µs (typical).

The MSP430F643x series are microcontroller configurations with an integrated 3.3-V LDO, a high performance 12-bit analog-to-digital (A/D) converter, comparator, two universal serial communication interfaces (USCI), hardware multiplier, DMA, four 16-bit timers, real-time clock module with alarm capabilities, LCD driver, and up to 74 I/O pins.
