1K位只添加存儲器

DS2502為1K位只添加存儲器，用于識別并存儲產(chǎn)品的相關(guān)信息。產(chǎn)品批號或特殊的產(chǎn)品信息可以通過最少的接口訪問—例如，微控制器的一個端口引腳。DS2502具有一個工廠光刻注冊碼，其中包括：48位唯一的序列號、8位CRC校驗(yàn)碼和8位家族碼(09h)以及1K位用戶可編程EPROM。由1-Wire?通信總線為DS2502的編程和讀取操作提供電源。\n\n 按照1-Wire協(xié)議，只需要一條信號線和一條地線實(shí)現(xiàn)數(shù)據(jù)的串行傳輸?？梢詫φ麄€器件進(jìn)行編程并根據(jù)需要增加寫保護(hù)。也可以多次編程添加新的數(shù)據(jù)，但器件的后續(xù)編程數(shù)據(jù)不能覆蓋已有數(shù)據(jù)。注意：每位只能從邏輯1編程到邏輯0，但永遠(yuǎn)不能從邏輯0更改為 ? 1024位電可編程只讀存儲器(EPROM)，采用更為經(jīng)濟(jì)的單條信號線和地線接口\n? 工廠激光刻入并經(jīng)過測試的唯一64位注冊碼(8位家族碼 + 48位序列號 + 8位CRC校驗(yàn)碼)，每個器件的注冊碼均不同，因而可確保絕對的可追溯性 \n? 內(nèi)置多點(diǎn)控制器，保證兼容于其它MicroLAN?產(chǎn)品\n? EPROM劃分為四個256位頁面，用于隨機(jī)存取數(shù)據(jù)包\n? 為防止數(shù)據(jù)被篡改，每個存儲頁面均可進(jìn)行永久性的寫保護(hù)\n? 該芯片具有“只添加”存儲功能，當(dāng)在EPROM內(nèi)存儲其它數(shù)據(jù)時，不會破壞已有數(shù)據(jù)\n? 結(jié)構(gòu)設(shè)計(jì)允許軟件對舊的存儲頁進(jìn)行數(shù)據(jù)修補(bǔ)，無需新打開可編程頁\n? 將控制線、地址線、數(shù)據(jù);
