I2C RTC，帶有涓流充電器

DS1340是一款實時時鐘(RTC)/日歷，與ST M41T00引腳兼容且功能相當(dāng)，包括軟件時鐘校準(zhǔn)。該器件還額外提供了VBACKUP引腳上的涓流充電功能、更低的計時電壓和振蕩器停止標(biāo)志。寄存器映射的塊訪問與ST器件相同。涓流充電器和標(biāo)志需要兩個單獨訪問的附加寄存器。時鐘/日歷提供秒、分、時、星期、日期、月和年信息。內(nèi)置電源檢測電路可檢測電源故障并自動切換到備用電源。該器件通過I2C雙向總線進行串行編程。\n\n ? ? ST M41T00的增強型替代選擇\n\n? 完全管理所有計時功能\n? RTC為秒、分、小時、星期、日期、月和年計數(shù)\n\n? 軟件時鐘校準(zhǔn)\n\n? 振蕩器停止標(biāo)志\n\n\n\n\n? 低功耗運行可延長備用電池運行時間\n? 計時電壓低至1.3V\n\n? 自動電源故障檢測和開關(guān)電路\n\n? 涓流充電功能\n\n\n\n\n? 三種工作電壓范圍（1.8V、3V和3.3V）支持使用傳統(tǒng)和現(xiàn)代電源總線的系統(tǒng)\n\n? 集成晶體的表面貼裝封裝(DS1340C)可節(jié)省額外空間并簡化設(shè)計\n\n? 通過簡單的串行端口與大多數(shù)微控制器進行接口\n? 快速(400kHz) I2C接口\n\n\n;
