说明

The Texas Instruments MSP430™ family of low-power microcontrollers consists of several devices featuring different sets of peripherals targeted for various applications. The architecture, combined with seven 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 MSP430FR572x and MSP430FR573x devices are microcontroller configurations with up to five 16-bit timers, comparator, universal serial communication interfaces (eUSCI) supporting UART, SPI, and I2C, hardware multiplier, DMA, real-time clock module with alarm capabilities, up to 33 I/O pins, and an optional high-performance 10-bit analog-to-digital converter (ADC).
