title="單片機">單片機" title="單片機">單片機" title="單片機">單片機（MCU）系列的最新產品——外設豐富、低引腳數的PIC12F(LF)1840和PIC16F(LF)1847。全新器件分別配備7 KB和14 KB片上閃存，高達1 K的RAM，是8和18引腳封裝產品中存儲容量最高的PIC® MCU。“LF”型號采用超低功耗（XLP）技術，工作電流小于40 µA/MHz，休眠電流低至20 nA。憑借豐富的外設和功能——包括mTouch™容性觸摸傳感和多種通信外設，這些通用MCU非常適合于家電（如咖啡壺、攪拌機和洗碗機）、消費類（如電池充電器、吸塵器、打印機和遙控器），以及汽車市場（如LED照明、無鑰門禁和車身電子）等各種應用。
　
　　Microchip的超低功耗技術一直是省電式MCU的行業標準，有助于提高各種應用的整體能效。PIC12F(LF)1840和PIC16F(LF)1847 MCU高度集成，具有獨立時基的多個PWM、1個支持LIN的EUSART以及多達2個I²C™/SPI接口。片上32級電壓參考可以作為一個簡單的數模轉換器，而數據信號調制器使得設計人員能夠利用各種輸入創建自定義位模式。
　
　　Microchip安防、單片機及技術開發部副總裁Steve Drehobl表示：“PIC12F(LF)1840和PIC16F(LF)1847體現了我們對低功耗和為我們的客戶提供市場上最具能效器件的承諾。全新MCU的大存儲容量、低功耗和創新外設的組合為我們的客戶提供了他們所需的工具，有助于延長電池壽命，縮小電路板空間，最重要的是降低了物料成本。”
