 微控制单元(Microcontroller Unit;MCU) ,又称单片微型计算机(Single Chip Microcomputer )或者单片机,是把中央处理器(Central Process Unit;CPU)的频率与规格做适当缩减,并将内存(memory)、计数器(Timer)、USB、A/D转换、UART、PLC、DMA等周边接口,甚至LCD驱动电路都整合在单一芯片上,形成芯片级的计算机,为不同的应用场合做不同组合控制。诸如手机、PC外围、遥控器,至汽车电子、工业上的步进马达、机器手臂的控制等,都可见到MCU的身影

Micro controller unit (MCU), also known as single chip microcomputer or single chip microcomputer, appropriately reduces the frequency and specification of central process unit (CPU), and integrates peripheral interfaces such as memory, counter, USB, a / D conversion, UART, PLC, DMA, and even LCD drive circuit on a single chip, A chip level computer is formed to do different combined control for different applications. MCU can be seen in mobile phones, PC peripherals, remote controls, automotive electronics, industrial stepping motors, robot arm control, etc
