K的RAM，是8和18引腳封裝產(chǎn)品中存儲容量最高的PIC® MCU。“LF”型號采用超低功耗（XLP）技術(shù)，工作電流小于40 µA/MHz，休眠電流低至20 nA。憑借豐富的外設(shè)和功能——包括mTouch™容性觸摸傳感和多種通信外設(shè)，這些通用MCU非常適合于家電（如咖啡壺、攪拌機(jī)和洗碗機(jī)）、消費類（如電池充電器、吸塵器、打印機(jī)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(yīng)用。
　
　　Microchip的超低功耗技術(shù)一直是省電式MCU的行業(yè)標(biāo)準(zhǔn)，有助于提高各種應(yīng)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(dá)2個I²C™/SPI接口。片上32級電壓參考可以作為一個簡單的數(shù)模轉(zhuǎn)換器，而數(shù)據(jù)信號調(diào)制器使得設(shè)計人員能夠利用各種輸入創(chuàng)建自定義位模式。
　
　　Microchip安防、單片機(jī)及技術(shù)開發(fā)部副總裁Steve Drehobl表示：“PIC12F(LF)1840和PIC16F(LF)1847體現(xiàn)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(chuàng)新外設(shè)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。”
