    Microcontrollers

    微控制器(MCU),也稱為微控制器單元、8位微控制器或單晶片,是嵌入式半導體裝置,用於電路板設計。本質上,它們是一個集成電路(IC)中的計算機。微控制器主要用於單功能嵌入式應用,不像微處理器那樣設計用於個人電腦、平板電腦和智能手機的通用工作。微控制器時鐘速度比起微處理器受到限制,主因是其非揮發性 Flash 程序記憶體存取速度相對較慢。

    微控制器由什麼組成?

    微控制器包含單個或多個處理器,以及記憶體和I/O外設。這些外設包括計時器、ADC(模擬數字轉換器)和DAC(精密數轉模轉換器)。

    微控制器的分類

    MCU微控制器設有標準晶片套裝,並帶有不同的針式插接器。套裝類型包括:

    • LQFP
    • PDIP
    • QFN
    • SOIC
    • SSOP
    • TQFP
    • TSSOP

    微控制器的特點

    • **嵌入式設計:**微控制器是專為嵌入式應用而設計的,通常與其他電子設備集成在一起。
    • **集成度高:**微控制器將處理器、記憶體和各種外設功能集成到一個芯片中,節省空間並降低了成本。
    • **低功耗:**適合用於需要長時間運行或電池供電。
    • **即時性:**能實時處理數據,並在極短的時間內做出反應。
    • **易於開發:**許多微控制器配有開發工具和豐富的支援文檔,使得軟體開發和系統設計相對容易。
    • **多樣的外設:**具有多種外設,如通訊接口(UART、SPI、I2C)、計時器、類比/數字轉換器等,可滿足各種應用的需求。
    • **多種包裝和尺寸:**提供多種封裝和尺寸選擇。
    • 靈活性:由於微控制器的可編程性,它們可以應用於各種不同的應用場景,並通過軟體更新實現功能擴展和改進。

    MCU微控制器/單晶片的應用

    MCU微控制器可以在許多技術和任何包含感測器、顯示器、用戶界面和可編程輸出控制器或致動器的電子設備中找到。它們可以在以下領域找到:

    • 電腦
    • 汽車
    • 機器人技術
    • 自動化
    • 醫療設備
    • 家用電器
    • 物聯網設備

    8位微控制器是什麼意思?

    8位微控制器具有數據總線寬度,可以一次處理的數據量。例如,8 位微控制器可以一次處理 8 位數據。常用的數據總線寬度包括 8 位、16 位和 32 位微控制器。

    什麼是 ARM 處理器核心?

    微控制器通常包含 ARM 微處理器核心。而ARM 是由 ARM Holdings 開發的一種架構,其他公司利用這種架構來制造微處理器和其他設備,例如片上系統 (SoC)。
