iButton RTC

iButton? RTC (DS1904)是一款堅固耐用、只需很少的硬件即可訪問的實時時鐘模塊。數(shù)據(jù)通過1-Wire?協(xié)議進行串行傳輸，該協(xié)議只需要一根數(shù)據(jù)線和一個接地回路。DS1904包含一個獨有的64位工廠印刻ROM和一個作為二進制計數(shù)器實現(xiàn)的實時時鐘/日歷。堅固耐用的MicroCan?封裝能夠耐受惡劣的應用環(huán)境，例如污垢、濕氣和沖擊等。使用配件，可將DS1904安裝在幾乎任何表面上，包括印刷電路板和塑料鑰匙扣。DS1904可用于向任何類型的電子設備或使用微控制器的嵌入式應用程序添加日歷、時間和日期戳、秒表、計時器、間隔定時器和日志等功能。 ? 二進制格式的實時時鐘/日歷\n\n? 使用與DS1994相同的二進制時間/日期表示法，但分辨率為1秒\n\n? 25°C時的時鐘精度優(yōu)于每月±2分鐘\n\n? 工作溫度范圍：-40°C至+85°C\n\n? 可運行超過10年\n\n? 由工廠印刻并測試的唯一64位注冊編碼（8位系列代碼 + 48位序列號 + 8位CRC測試儀代碼）可確保產(chǎn)品可追溯，因為沒有兩個器件是相同的\n\n? 用于MicroLAN的多點控制器\n\n? 通過瞬時接觸進行數(shù)字識別和信息存儲\n\n? 基于芯片的數(shù)據(jù)載體以緊湊的方式存儲信息\n\n? 可以在固定到物體上時訪問數(shù)據(jù)\n\n? 通過單個數(shù)字信號以16.3kb;
