The microcontroller controlling a car's engine, for example, has to work in temperature extremes that a normal computer generally cannot handle. A car's microcontroller in Alaska has to work fine in -30 degree F (-34 C) weather, while the same microcontroller in Nevada might be operating at 120 degrees F (49 C).
In many products, such as microwave ovens, the demand on the CPU is fairly low and price is an important consideration. In these cases, manufacturers turn to dedicated microcontroller chips -- chips that were originally designed to be low-cost, small, low-power, embedded CPUs. The Motorola 6811 and Intel 8051 are both good examples of such chips. There is also a line of popular controllers called "PIC microcontrollers" created by a company called Microchip. By today's standards, these CPUs are incredibly minimalistic; but they are extremely inexpensive when purchased in large quantities and can often meet the needs of a device's designer with jus

微型控制器可以实现在一个普通计算机不能承受的温度中工作，以控制汽车引擎的微型处理器为例，在阿拉斯加，一辆汽车的微型控制器要能够在华氏-30度（-34C）的环境中正常工作，然而在内华达（美国州名），同一个微型控制器要能够实现在华氏120度（49C）的环境中正常工作。
在诸如微波炉等很多产品中，其对处理器（CPU）的需求量非常小，且价格因素占有很重要的地位。在这种情形下，制造商开始致力于转向使用微型控制芯片 —— 一种自行设计的，以便实现低成本，小规格，低消耗的嵌入式处理器（CPU）。摩托罗拉的6811和英特尔的8051便是这种芯片的很好的代表。另外，现在同样也流行另一种由Microchip公司研发的叫做“PIC 微型控制器”的控制器。按照现行的标准，这些处理器（CPU）可以达到难以置信的微型，但是当大量采购时，他们是极其的便宜并且也通常能够满足设备设计人员仅仅需要一台的要求。
(这篇文章不难，我对Microcontroller的理解是微型控制器，不知到是否准确，其他的地方没有问题，希望对你有用！)
