【正文】 imer loops. Universal Asynchronous Receiver/Transmitter (UART) block makes it possible to receive and transmit data over a serial line with very little load on the CPU. For those wanting ether one can use an external chip like Crystal Semiconductor CS8900A, Realtek RTL8019, or Microchip ENC 28J60. All of them allow easy interfacing with low pin count. 無(wú) 錫 職 業(yè) 技 術(shù) 學(xué) 院 畢業(yè)設(shè)計(jì)說(shuō)明書(shū)（英文翻譯） 5 中文翻譯： 單片機(jī) 單片機(jī)即單片微型計(jì)算機(jī)，是把中央處理器、存儲(chǔ)器、定時(shí) /計(jì)數(shù)器、輸入輸出接口都集成在一塊集成電路芯片上的微型計(jì)算機(jī)。C) is a functional puter systemonachip. It contains a processor core, memory, and programmable input/output peripherals. Microcontrollers include an integrated CPU, memory (a small amount of RAM, program memory, or both) and peripherals capable of input and output. It emphasizes high integration, in contrast to a microprocessor which only contains a CPU (the kind used in a PC). In addition to the usual arithmetic and logic elements of a general purpose microprocessor, the microcontroller integrates additional elements such as readwrite 無(wú) 錫 職 業(yè) 技 術(shù) 學(xué) 院 畢業(yè)設(shè)計(jì)說(shuō)明書(shū)（英文翻譯） 3 memory for data storage, readonly memory for program storage, Flash memory for permanent data storage, peripherals, and input/output interfaces. At clock speeds of as little as 32KHz, microcontrollers often operate at very low speed pared to microprocessors, but this is adequate for typical applications. They consume relatively little power (milliwatts or even microwatts), and will generally have the ability to retain functionality while waiting for an event such as a button press or interrupt. Power consumption while sleeping (CPU clock and peripherals disabled) may be just nanowatts, making them ideal for low power and long lasting battery applications. Microcontrollers are used in automatically controlled products and devices, such as automobile engine control systems, remote controls, office machines, appliances, power tools, and toys. By reducing the size, cost, and power consumption pared to a design using a separate microprocessor, memory, and input/output devices, microcontrollers make it economical to electronically control many more processes. The majority of puter systems in use today are embedded in other machinery, such as automobiles, telephones, appliances, and
