在電腦科裡,MCU不代表漫威宇宙(Marvel Cinematic Universe),MCU這三個字母卻是代表微形控制單元(Microcontroller Unit),或稱單板電腦,用途可多著呢!風琴奇俠會於本節目為你介紹最常用的幾款MCU,包括Arduino, Micro:bit, M5 Stack等等。
A microcontroller (MCU for microcontroller unit) is a small computer on a single metal-oxide-semiconductor (MOS) integrated circuit chip. In modern terminology, it is similar to, but less sophisticated than, a system on a chip (SoC); an SoC may include a microcontroller as one of its components. A microcontroller contains one or more CPUs (processor cores) along with memory and programmable input/output peripherals. Program memory in the form of ferroelectric RAM, NOR flash or OTP ROM is also often included on chip, as well as a small amount of RAM. Microcontrollers are designed for embedded applications, in contrast to the microprocessors used in personal computers or other general purpose applications consisting of various discrete chips.
單晶片,全稱單晶片微電腦(英語:single-chip microcomputer),又稱微控制器(microcontroller),是把中央處理器、記憶體、定時/計數器(timer/counter)、各種輸入輸出介面等都整合在一塊積體電路晶片上的微型電腦。與應用在個人電腦中的通用型微處理器相比,它更強調自供應(不用外接硬體)和節約成本。它的最大優點是體積小,可放在儀表內部,但儲存量小,輸入輸出介面簡單,功能較低。由於其發展非常迅速,舊的單晶片的定義已不能滿足,所以在很多應用場合被稱為範圍更廣的微控制器;由於單晶片微電腦常用於當控制器故又名single chip microcontroller。「單晶片」是台灣對單晶片的稱呼;中國大陸主要採用「单片机」的稱呼,英文縮寫為MCU。
