Lesi sizindalwazi sisetshenziswa ibhizinisi noma amabhizinisi aphethwe yi-Informa PLC futhi wonke amalungelo okukopisha ahlala kubo.Ihhovisi elibhalisiwe le-Informa PLC yi-5 Howick Place, e-London SW1P 1WG.Ibhaliswe eNgilandi naseWales.Inombolo yepholisi: 8860726.
U-Rohm umemezele ukuthuthukiswa kwesixazululo sokushaja okungenantambo kwezimoto ngokuxhumana okuhlanganisiwe kwe-Near-field (NFC).Ihlanganisa i-Rohm’s automotive-grade (AEC-Q100 qualified) yokulawula ukudluliswa kwamandla angenantambo i-IC (BD57121MUF-M) ne-STMicroelectronics' NFC Reader IC (ST25R3914) kanye ne-8-bit microcontroller (STM8A series).
Ngaphezu kokuthobela izinga le-Qi le-WPC elisekela i-EPP (Nweba Iphrofayela Yamandla), eyenza ishaja inikeze amandla afinyelela kwangu-15 W, umklamo onamakhoyili amaningi kuthiwa uvumela indawo yokushaja ebanzi (ibanga lokushaja elikhudlwana elingu-2.7X uma liqhathaniswa ukucushwa kwekhoyili eyodwa).Lokhu kusho ukuthi abathengi akufanele bakhathazeke ngokuqondanisa ngqo ama-smartphones abo endaweni yokushaja enikeziwe ukuze bakwazi ukushaja ngaphandle kwentambo.
Ukushaja okungenantambo kwe-Qi kwamukelwe yi-European Automotive Standards Group (CE4A) njengezinga lokushaja ezimotweni.Ngo-2025, kwabikezelwa ukuthi izimoto eziningi zizobe sezifakwe amashaja asuselwa ku-Qi.
I-NFC inikeza ukuqinisekiswa komsebenzisi ukuze kuvunyelwe ukuxhumana kwe-Bluetooth/Wi-Fi ngamayunithi e-infotainment, amasistimu okukhiya izicabha/okuvula, kanye nokuqalisa injini.I-NFC iphinda inike amandla izilungiselelo zemoto ezenziwe ngokwezifiso kubashayeli abaningi, njengokuma kwesihlalo nesibuko, amasethi angaphambili we-infotainment, namasethi angaphambili endawo okuyiwa kuyo.Lapho isebenza, i-smartphone ifakwa kuphedi yokushaja ukuze kuqalwe ngokuzenzakalelayo ukwabelana ngesikrini nesistimu ye-infotainment neyokuzulazula.
Ngaphambilini, lapho uxhuma ama-smartphone kumasistimu e-infotainment, bekudingeka ukuthi kwenziwe ukubhanqa okwenziwa ngesandla kudivayisi ngayinye.Kodwa-ke, ngokuhlanganisa ukushaja okungenantambo kwe-Qi nokuxhumana kwe-NFC, i-Rohm yenze kwaba nokwenzeka ukuthi ingagcini ngokushaja amadivaysi eselula njengama-smartphone, kodwa futhi yenza i-Bluetooth noma i-Wi-Fi yokumatanisa kanyekanye ngokusebenzisa ukuqinisekiswa kwe-NFC.
I-ST25R3914/3915 ye-NFC yokufunda ye-automotive-grade ICs iyahambisana ne-ISO14443A/B, ISO15693, FeliCa, kanye ne-ISO18092 (NFCIP-1) Active P2P.Zihlanganisa ingemuva le-analogi elibonisa lokho okuthiwa kuzwela umamukeli osezingeni eliphezulu, iletha ukusebenza kokutholwa kwento yangaphandle kumakhonsoli esikhungo sezimoto.Ngokwezinga le-Qi, umsebenzi wokuthola into yangaphandle ukuze uthole izinto zensimbi ufakiwe.Lokhu kuvimbela ukuwohloka noma ukulimala ukuthi kungenzeki ngenxa yokukhiqiza ukushisa okukhulu uma kwenzeka into eyinsimbi ibekwa phakathi komthumeli nomamukeli.
I-ST25R3914 ihlanganisa umsebenzi we-ST's proprietary Automatic Antenna Tuning.Ivumelana nezinguquko zendawo ezungezile ukuze kuncishiswe imithelela evela ezintweni zensimbi eduze kothi lokufunda, njengokhiye noma izinhlamvu zemali ezibekwe kukhonsoli emaphakathi.Ngaphezu kwalokho, i-MISRA-C: 2012-compliant RF middleware iyatholakala, esiza amakhasimende ehlise umzamo wawo wokuthuthukisa isoftware.
Uchungechunge lwe-STM8A lwezimoto lwe-8-bit MCU luza ngamaphakheji ahlukahlukene nosayizi benkumbulo.Amadivayisi anedatha eshumekiwe Ama-EEPROM aphinde anikezelwe, okuhlanganisa amamodeli ahlome nge-CAN anebanga lezinga lokushisa elinwetshiwe eliqinisekisiwe elifika ku-150°C, okuwenza afanelekele kahle izinhlelo zokusebenza zezimoto ezihlukahlukene.
