Defining Microcontroller

微控制器可以称为单个集成电路上包含的小型计算机。它包含处理器核心，可编程输入/输出外围设备和内存。程序内存中包含一个小型RAM以及NOR FLASH和OTP ROM。与很少在个人计算机和其他通用应用中使用的微处理器相反，微控制器是为嵌入式应用设计的。

The automatically controlled products and devices contain microcontrollers. For example automobile engine control systems, remote controls, implantable medical devices, toys, office machines, power tools and other type of embedded systems. Microcontrollers are more economical; than micro processors and have a reduced size as well as cost as compared to microprocessors. The design is also simpler as compared to a microprocessor system with a separate microprocessor, input/output devices and memory with an enhanced functionality of digital controlling more devices and processes. For controlling non digital and non electronic systems, mixed signal microcontrollers are the common integrating analog components needed.

对于低功耗，一些微控制器在以时钟速率频率运行时使用四个单词，可低至4 kHz。他们通常在等待诸如按钮按下或其他中断之类的事件时保留其功能。它们也非常适合持续的更好的应用程序，因为在纳米瓦特（Nano Watt）睡觉时（CPU时钟和大多数外围设备）的功耗（CPU时钟和大多数外围设备）。微控制器还提供了至关重要的角色，它们的作用像具有更高功耗和时钟速度的数字信号处理器。

嵌入式系统和微控制器

The microcontrollers are used as an embedded system and have a processor and memory along with peripherals. A majority of them are often embedded in other types of machineries like automobiles, appliances, telephones and the peripherals of the computer system these are also termed as embedded systems. Some embedded systems have the minimum requirement for memory and program length; have low software complexity and no operating system, while some other embedded systems are highly sophisticated. Switches , relays, LED’s, small or custom LCD displays, solenids, sensors of data such as humidity, temperature, light level etc, and radio frequency deices are the typical and most commonly used input and output devices. Embedded systems often do not have human interaction devices of any kind and usually lack screen, keyboard, printers, disks and other input and out put devices of a computer.

Features and various aspects of microcontroller

一个小ocontroller must be able to provide predictable and real time response to the events occurring in embedded systems which they are in control of. The programs of microcontroller should be contained and must fit in the available on chip program memory, as an external system with expandable memory would be more costly. The high level language and the assembler language codes are codes are converted by the compilers and assemblers into a machine code compact enough for storage in the microcontroller’s memory. The program memory can be read only memory (programmable only at the factory), permanent memory or erasable read only memory. The input/output pins (GPIO) contained in microprocessor are several to dozen in number. If configured to an input state, the GPIO pins read sensors or external signs. When configured to an output sate, the pins can drive the external devices such as motors or LED’s.

Initially the microcontrollers were programmed only in the assembly language, but now other high level programming languages are also used to target microcontrollers. Some versions of general purpose programming language are used, for example c programming language while some other languages are designed specially for microcontroller programming. Some microcontrollers contain environments which act as an aid in developing creating languages. Some vendors of microcontrollers make tools which make it easy to adopt their hardware. These tools are free of cost.
