iButton 1K位只添加

iButton? 1K位只添加(DS1982)是一種堅(jiān)固的讀/寫(xiě)數(shù)據(jù)載體，可以識(shí)別和存儲(chǔ)與產(chǎn)品或攜帶者的相關(guān)信息。該信息可以通過(guò)最少的硬件訪(fǎng)問(wèn)，例如微控制器的一個(gè)端口引腳。DS1982具有一個(gè)工廠(chǎng)光刻的注冊(cè)碼，其中包括：一個(gè)唯一的48位序列碼，8位CRC校驗(yàn)碼，以及8位家族碼(09h)，此外還具有1K位的用戶(hù)可編程EPROM。編程和讀取DS1982所需要的電源全部來(lái)自1-Wire通信線(xiàn)。采用1-Wire協(xié)議，即只需要一條信號(hào)線(xiàn)和一條地線(xiàn)，即可實(shí)現(xiàn)數(shù)據(jù)的串行傳輸?？蓪?duì)整個(gè)器件進(jìn)行編程，并根據(jù)需要加入寫(xiě)保護(hù)。也可以采用順序編程該器件，多次編程添加新的數(shù)據(jù)，而不是覆蓋已有的數(shù)據(jù)。注意：每位只能由邏輯 ? 1024位電可編程只讀存儲(chǔ)器(EPROM)，采用更為經(jīng)濟(jì)的單根信號(hào)線(xiàn)加地線(xiàn)接口方式\n? EPROM劃分為四個(gè)256位頁(yè)面，用于隨機(jī)存儲(chǔ)數(shù)據(jù)包\n? 為防止數(shù)據(jù)丟失，每個(gè)存儲(chǔ)頁(yè)均可進(jìn)行永久性的寫(xiě)保護(hù)\n? 該芯片具有“只添加”存儲(chǔ)功能，當(dāng)在EPROM內(nèi)存儲(chǔ)其他數(shù)據(jù)時(shí)，也不會(huì)破壞已有數(shù)據(jù)\n? 結(jié)構(gòu)設(shè)計(jì)上允許軟件來(lái)對(duì)一個(gè)舊存儲(chǔ)頁(yè)進(jìn)行修補(bǔ)數(shù)據(jù)，而不需要新打開(kāi)一個(gè)編程頁(yè)\n? 將控制線(xiàn)、地址線(xiàn)、數(shù)據(jù)線(xiàn)、電源和可編程信號(hào)線(xiàn)減少至一條線(xiàn)\n? 8位家族碼通知讀寫(xiě)器按照DS1982要求進(jìn)行通信\n? -40°C至+85°C溫度范圍內(nèi)，讀取數(shù)據(jù)電壓范圍為2.8V至6.0V；在-40°C至+50°C溫度范;
