iButton 16K位只添加

iButton? 16Kb“僅添加”(DS1985)是一款堅(jiān)固耐用的讀/寫數(shù)據(jù)載體，可識別和存儲與其所連接的產(chǎn)品或人員相關(guān)的信息。只需很少的硬件即可訪問此信息：例如，微控制器的單個端口引腳。DS1985由工廠印刻注冊編碼組成，其中包括唯一的48位序列號、8位CRC和8位系列代碼(0BH)加上用戶可編程的16Kb EPROM。DS1985的編程和讀取功能完全來自1-Wire通信線路。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。如果需要，整個器件可以進(jìn)行編程，然后進(jìn)行寫保護(hù)?；蛘撸梢詫ζ骷M(jìn)行多次編程，每次對器件進(jìn)行后續(xù)編程時，都會將新數(shù)據(jù)附加到現(xiàn)有數(shù)據(jù)，但不會覆 ? 16384位電可編程只讀存儲器(EPROM)通過一個信號加上地線即可進(jìn)行經(jīng)濟(jì)實(shí)惠的通信\n\n?

UniqueWare iButton器件

UniqueWare? iButton? devices (DS1982U/DS1985U) are factory-programmed versions of the iButton Add-Only devices, DS1982 (1024 bit) and the DS1985 (16Kb) respectively. They differ from the regular devices in their custom ROM family codes (see Ordering Information) and the UniqueWare Identifier 5E7h in \n? 1024 bits or 64kbits electrically programmable read only memory (EPROM) communicates with the economy of one signal plus ground \n? Unique, factory lasered and tested 64-bit registration number (8-bit family code, 36-bit serialization, 12-bit UniqueWare identifier 5E7h, 8-bit CRC tester) assures;
