MSP430系列单片机是美国德州仪器（TI）1996年开始推向市场的一种16位超低MSP430单片机功耗、具有精简指令集（RISC）的混合信号处理器（Mixed Signal Processor）。称之为混合信号处理器，是由于其针对实际应用需求，将多个不同功能的模拟电路、数字电路模块和微处理器集成在一个芯片上，以提供“单片机”解决方案。该系列单片机多应用于需要电池供电的便携式仪器仪表中。-Texas Instruments MSP430 MCU is (TI) 1996 began to market a 16-bit ultra-low-power MSP430 microcontroller with a reduced instruction set (RISC) mixed-signal processor (Mixed Signal Processor). Called mixed-signal processors, due to its demand for practical application, the plurality of different functional analog circuit, digital circuit modules and integrated on a single chip microprocessor, to provide a "single-chip" solution. The family of microcontrollers and more applications that require battery-powered portable instrumentation.
