產(chǎn)品概述
RTC 時(shí)鐘模塊是一款低功耗，具有 56 字節(jié)非失性 RAM 的全 BCD 碼時(shí)鐘日歷實(shí)時(shí)時(shí)鐘模塊，芯片可以提供秒，分，小時(shí)等信息，每一個(gè)月的天數(shù)能自動(dòng)調(diào)整。并且有閏年補(bǔ)償功能。AM/PM 標(biāo)志位決定時(shí)鐘工作于 24 小時(shí)或 12 小時(shí)模式，芯片有一個(gè)內(nèi)置的電源感應(yīng)電路，具有掉電檢測(cè)和電池切換功能。當(dāng)單片機(jī)斷電情況下，可以通過(guò)一個(gè)電池讓單片機(jī)項(xiàng)目時(shí)間保持記錄，完善的數(shù)據(jù)記錄。
