iButton 1Kb/4Kb存儲器概述

iButton? 1Kb/4Kb存儲器(DS1992)是一款堅固耐用的讀/寫數(shù)據(jù)載體，可用作本地化數(shù)據(jù)庫，只需很少的硬件即可輕松訪問。非易失性存儲器和可選的計時功能提供了一種簡單的解決方案來存儲和檢索與iButton器件所連接的物體有關(guān)的重要信息。數(shù)據(jù)通過1-Wire?協(xié)議進(jìn)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。\n\n 暫存區(qū)是一個附加頁，在寫入存儲器時充當(dāng)緩沖區(qū)。數(shù)據(jù)首先寫入暫存區(qū)，然后可以在其中回讀。數(shù)據(jù)得到驗證后，復(fù)制暫存區(qū)命令會將數(shù)據(jù)傳輸?shù)酱鎯ζ鳌４诉^程可在修改存儲器時確保數(shù)據(jù)完整性。每個DS199_均有工廠印刻的48位序列號作為唯一標(biāo)識，確保產(chǎn)品可追溯。堅固耐 ? 4096位讀/寫非易失性存儲器(DS1993)\n\n? 1024位讀/寫非易失性存儲器(DS1992)\n\n? 256位暫存區(qū)確保數(shù)據(jù)傳輸?shù)耐暾診n\n? 存儲器分為多個256位頁面，用于分包數(shù)據(jù)\n\n? 通過嚴(yán)格的讀/寫協(xié)議確保數(shù)據(jù)完整性\n\n? 工作溫度范圍：-40°C至+70°C\n\n? 數(shù)據(jù)保留超過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(jìn)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;
