单片机指的是一种集成电路芯片。作为一种电子技术肇始于20世纪80年代,当时的只有4位、8位单片机,发展到现在,已出现32位300M的高速单片机。它是采用超大规模集成电路技术,把具有数据处理能力的中央处理器CPU随机存储器RAM、只读存储器ROM、多种I/O口和中断系统、定时器/计时器,甚至还包括显示驱动电路、脉宽调制电路、模拟多路转换器、A/D转换器等电路的功能集成到一块
Microcontroller refers to an integrated circuit chip. As an electronic technology started in the 1980s, when only 4, 8 microcontroller, development up to now, there have been 32 300M high-speed microcontroller. It is the use of VLSI technology, the central processing unit CPU with data processing RAM random access memory, ROM, a variety of I / O and interrupt system, timer / timer, and even includes the display driver circuit , Pulse width modulation circuit, analog multiplexer, A / D converter and other circuit functions integrated into one
