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。-MSP430 series MCU is Texas instruments (TI) in 1996 began to market a 16-bit low MSP430 MCU, power consumption is reduced instruction set (RISC) of the Mixed Signal Processor (Mixed Signal Processor). Called the mixed signal processor, it is because of its according to the actual application requirements, will be a number of different functions of analog circuit, digital circuit module and integrated on a single chip microprocessor, to provide "MCU" solutions. This series of single-chip microcomputer applied to need more batteries in portable instruments and meters.
