St25tv512 yotsekedwa yowoneka bwino yachitetezo, ISO 15693 Mtundu wa Protocol NFC 5 Chitetezo cholembedwa

Stmincroeletronics St25tv512 Mtundu 5 NFC tag t ic ic ic imaphatikiza zosavuta ndipo kuwunika kwa ISO 15693 Khadi la Khadi la Proximity ndi chitetezo chokhazikika, Kuteteza deta ndi chinsinsi cha ogwiritsa ntchito.
Ubwino wa ISO 15693 ma tags pamwamba pa iso 14443 Matagi amaphatikiza anternas ang'onoang'ono, Kutalikirana kwakutali ndi kusinthana kotsimikizika. Monga iso yokha 15693 IC yokhala ndi kupezeka kwa Tamper, St25tv512 imapangitsa ma tag omwe amagwiritsidwa ntchito poyendetsa tamper, Kuwunikira kwakale kwa magetsi ndi zina zotetezeka kwambiri, ochepera, Zosavuta kukhazikitsa komanso zosavuta kuwerenga, ndipo amatha kulumikizana ndi mafoni kapena owerenga rfid. Chip chimakhala choyenera kwambiri kwa makompyuta kapena malonda aluso.
STMCREELETETOMINGICKICTOMICKICICKICICICKITSE CHIKONDI CHA NFC, Kutsimikizika kwazogulitsa ndi kukhulupirika kwa mankhwala osokoneza bongo pamsika wapamwamba monga katundu wapamwamba komanso ma prormaceuticals. Kuphatikiza pa kupezeka kwa Tamper, Zojambula zina zimateteza milandu yogwiritsa ntchito, Makampani a Smart, Mapulogalamu ndi mawonekedwe a digito, kuphatikiza zikwangwani zanzeru, Kutsata katundu, mwayi wolowera, Kutsimikizika ndi mapulogalamu apakati ngati masewera ngati masewera.
Chidziwitso chilichonse cha St25tv512 chimakhala ndi chizindikiritso cha 14-bit ndipo chimasainidwa pogwiritsa ntchito stamroectronics khulupirirani25^Tm njira yotsimikizira komwe kudachokera ndikupewa ma pirate. Kugwiritsa ntchito kwa ogwiritsa ntchito / kulemba ntchito ndi mawu achinsinsi mpaka 64-bit encryption algorithms ndi chitetezo chotseka. Tag (Ipha) Makina a Mode ndi Makina Osiyanasiyana a Stocks ndi Data / Kusintha Malo Ofuna Kuteteza Chinsinsi Chogula.
The St25tv512 IC imathandizira onse a ISO / IEC 15693 kusazichedwa, kuvomera, Mitundu ya Subcarrier ndi mitengo ya deta, ndi kugwirizanitsa block werengani / lembani mitundu yosiyanasiyana, kuphatikiza kuwerengera mwachangu mpaka 53 Kbit/s. Kukula kwa 512-pang'ono kumalola kukumbukira kukumbukira kukumbukira, ndi kukana kwa ERUSURY kwa ocheperako 100,000 Zoyenda ndi kusungidwa kwa deta mpaka 60 zaka. Oyenera kusinthidwa kwanthawi yayitali.
Sankhani mndandanda wa st25tv nfc ngati khadi yofikira ndikuthandizira ntchito ya deta ya data, Khadi lolowera silidzakopedwa.
