单片机,全称单片微型计算机(英语:single-chip microcomputer),又称微控制器(microcontroller),是把中央处理器、存储器、定时/计数器(timer/counter)、各种输入输出接口等都集成在一块集成电路芯片上的微型计算机。与应用在个人电脑中的通用型微处理器相比,它更强调自供应(不用外接硬件)和节约成本。它的最大优点是体积小,可放在仪表内部,但存储量小,输入输出接口简单,功能较低。由于其发展非常迅速,旧的单片机的定义已不能满足,所以在很多应用场合被称为范围更广的微控制器;由于单片机微电脑常用于当控制器故又名single chip microcontroller。单芯片是台湾对单片机的称呼;中国大陆主要采用“单片机”的称呼,英文缩写为MCU。

A microcontroller (or MCU for microcontroller unit) is a small computer on a single integrated circuit. In modern terminology, it is a System on a chip or SoC. A microcontroller contains one or more CPUs (processor cores) along with memory and programmable input/output peripherals. Program memory in the form of Ferroelectric RAM, NOR flash or OTP ROM is also often included on chip, as well as a small amount of RAM. Microcontrollers are designed for embedded applications, in contrast to themicroprocessors used in personal computers or other general purpose applications consisting of various discrete chips.
