DS1321

靈活的非易失控制器，帶有鋰電池

帶鋰電池監(jiān)控器的DS1321靈活非易失性控制器是一款CMOS電路，解決了將CMOS SRAM轉(zhuǎn)換為非易失性存儲(chǔ)器的應(yīng)用問(wèn)題。監(jiān)控輸入功率是否發(fā)生超出容差的情況。當(dāng)檢測(cè)到這種情況時(shí)，芯片使能輸出會(huì)被禁止以實(shí)現(xiàn)寫(xiě)保護(hù)，并且電池會(huì)開(kāi)啟以向SRAM提供不間斷電源。特殊電路采用低泄漏CMOS工藝，能夠以超低的電池消耗提供高精度的電壓檢測(cè)。一個(gè)DS1321可支持多達(dá)四個(gè)以三種存儲(chǔ)器配置中的任意一種排列的SRAM。\n\n 除了備用電池支持之外，DS1321執(zhí)行的重要功能還包括監(jiān)控鋰電池剩余電量并在電池電量耗盡之前發(fā)出警告。由于鋰備用電池的開(kāi)路電壓在其使用壽命的大部分時(shí)間內(nèi)保持相對(duì)恒定，因此準(zhǔn)確的; ? 將CMOS SRAM轉(zhuǎn)換為非易失性存儲(chǔ)器\n\n? 當(dāng)VCC超出容差時(shí)，對(duì)SRAM實(shí)施無(wú)條件寫(xiě)保護(hù)\n\n? 發(fā)生VCC電源故障時(shí)自動(dòng)切換至電池備用電源\n\n? 靈活的存儲(chǔ)器結(jié)構(gòu)\n? 模式0：4組，每組1個(gè)SRAM\n\n? 模式1：2組，每組2個(gè)SRAM\n\n? 模式2：1組，每組4個(gè)SRAM\n\n\n\n\n? 監(jiān)控鋰電池的電壓并在即將發(fā)生電池故障時(shí)發(fā)出預(yù)警\n\n? 低電平有效時(shí)發(fā)出低電池電量狀態(tài)信號(hào)電池警告輸出信號(hào)\n\n? 發(fā)生電源故障時(shí)復(fù)位處理器，并在系統(tǒng)上電期間使處理器保持復(fù)位狀態(tài)\n\n? 可選5%或10%電源故障檢測(cè)\n\n? 16引腳PDIP、1;
