Iqhosha lememori yaseDallas

Ibutton yegama eliqhelekileyo leqhosha lokuchonga le-elektroniki elipakishwe kwingqekembe -} yentsimbi yentsimbi. Ikwabizwa ngokuba yimemori yeDallas okanye imemori yoqhakamshelwano. Nangona kusoloko kubizwa ngokungalunganga njenge "isitshixo" semagneti ", akukho nto imbitileyo kuyo. Ngapha koko, -} i-microchip esebenza kwiprotocol yedijithali ifihliwe ngaphakathi.

Ngokwesiqhelo, ibutton ithetha indlela yomzimba yesitshixo kunye nomfundi- ingqekembe ejikelezileyo kunye nabafowunelwa ababini. Kuba isakhelo esijikelezileyo, kukho umahluko oninzi ovela kulowo umnini weplastiki oqhelekileyo ngomngxunya, i-pendants, njl.

Isiphatho seKhadi leMali siyintsingiselo yokuchaneka kwe-nylon yezixhobo ezixubileyo, ezine-acid {{0} {2} {2} {2} {2} {2} {2} {2} {2} {2} {2} {2} {2} {2} {2} {2} {2} {2} {2} {2} {2} {2} Isiphatho sihambelana neKhadi le-TM kwaye linokusetyenziswa njengeqhosha lokuvula lwehotele, iikrikhi zeSauni kunye nezitshixo ezahlukeneyo zeMali. Intle, kulula ukuyiphatha kwaye inyange.

I-DS1990A - chip yi-chip yedatha eyomeleleyo enokusetyenziswa njengenombolo yobhaliso lwe-elektroniki kwiinkqubo zokuchazwa kwe-elektroniki. Idatha idluliselwe ngokusebenzisa i-1 -}} i-wire kunye neProtocol enesihloko esinye kuphela kunye nokubuya komhlaba. I-DS1990A ibandakanya i-64-bit bit Rom yokuqinisekisa ukulandelela ngokupheleleyo. Iphakheji ye-ibutton enombhobho iyamelana neemeko ezifana nothuli, ukufuma kunye nokunyikima. Ubume beqhosha le-DS1990a lunokulungelelanisa ngokuzenzekelayo kunye nentloko ebhaliweyo ebhaliweyo / yokubhala, elula kakhulu kubasebenzisi abasebenza. Izixhobo ezahlukeneyo Vumela i-DS1990A ifakwe kuyo nayiphi na into, ezinje ngeziqulatho ezahlukeneyo, iitreyi, iingxowa, njl.
