4-kbit EEPROM iButton

iButton DESCRIPTION The DS1973 4Kb EEPROM iButton is a rugged read/write data carrier that identifies and stores relevant information about the product or person to which it is attached. This information can be accessed with minimal hardware, for example a single port pin of a micro-controller.

iButton 4Kb EEPROM

iButton? 4Kb EEPROM (DS1973)是一款堅(jiān)固耐用的讀/寫(xiě)數(shù)據(jù)載體，可識(shí)別和存儲(chǔ)與其所連接的產(chǎn)品或人員相關(guān)的信息。只需很少的硬件即可訪問(wèn)此信息：例如，微控制器的單個(gè)端口引腳。DS1973由工廠印刻注冊(cè)編碼組成，其中包括唯一的48位序列號(hào)、8位CRC和8位系列代碼(23H)加上4096位EEPROM。DS1973的編程和讀取功能完全來(lái)自1-Wire?通信線路。存儲(chǔ)器的結(jié)構(gòu)為16頁(yè)，每頁(yè)256位。64位注冊(cè)編碼作為唯一標(biāo)識(shí)，確保產(chǎn)品可追溯。數(shù)據(jù)通過(guò)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(gè)接地回路。堅(jiān)固耐用的MicroCan封裝能夠耐受惡劣的應(yīng)用環(huán)境，例如污垢、 ? 4096位電可擦除可編程只讀存儲(chǔ)器(EEPROM)\n\n? 過(guò)驅(qū)模式將通信速度提升至142kbps\n\n? 256位暫存區(qū)確保數(shù)據(jù)傳輸?shù)耐暾診n\n? 存儲(chǔ)器分為多個(gè)256位頁(yè)面，用于分包數(shù)據(jù)\n\n? 將控制、地址、數(shù)據(jù)和電源減少到單個(gè)數(shù)據(jù)引腳\n\n? 8位系列代碼規(guī)定了DS1973與讀取器的通信要求\n\n? 在2.8V至6.0V的寬電壓范圍內(nèi)讀取和寫(xiě)入（-40°C至+85°C）;
