Rohm Yana Haɗa Cajin Mara waya ta Automotive tare da NFC

Wannan rukunin yanar gizon kasuwanci ne ko kasuwanci mallakar Informa PLC kuma duk haƙƙin mallaka yana tare da su.Ofishin rajista na Informa PLC shine 5 Howick Place, London SW1P 1WG.An yi rajista a Ingila da Wales.Farashin 8860726.

Rohm ya ba da sanarwar haɓaka hanyar caji mara waya ta mota tare da haɗin haɗin filin kusa (NFC).Yana haɗa tare da Rohm's automotive-grade (AEC-Q100 qualified) mara waya ta watsa wutar lantarki IC (BD57121MUF-M) tare da STMicroelectronics' NFC Reader IC (ST25R3914) da 8-bit microcontroller (STM8A jerin).

Baya ga kasancewa mai bin ka'idodin WPC na Qi mai goyan bayan EPP (Extend Power Profile), wanda ke ba da damar caja don samar da wutar lantarki har zuwa 15 W, an ce ƙirar coil da yawa don ba da damar caji mai faɗin yanki (2.7X mafi girman kewayon caji gaba da gaba). daidaitawar coil guda ɗaya).Wannan yana nufin cewa masu amfani ba sa buƙatar damuwa game da daidaita wayoyin su daidai da wurin da aka tanadar da caji don samun damar yin caji ba tare da waya ba.

Ƙungiya ta Ƙididdiga Masu Mota ta Turai (CE4A) ta karɓi caji mara waya ta Qi a matsayin ma'aunin caji a cikin motoci.Nan da shekarar 2025, an yi hasashen cewa galibin motoci za su kasance masu sanye da cajar mara waya ta tushen Qi.

NFC tana ba da amincin mai amfani don ba da izinin sadarwar Bluetooth/Wi-Fi tare da raka'a na bayanan bayanai, tsarin kulle ko buɗewa, da fara injin.NFC kuma yana ba da damar saitunan abin hawa na musamman don direbobi da yawa, kamar wurin zama da sanya madubi, saiti na bayanan bayanai, da saitin saiti na kewayawa.A cikin aiki, ana sanya wayar hannu akan kushin caji don fara raba allo ta atomatik tare da tsarin infotainment da kewayawa.

A baya can, lokacin haɗa wayoyin hannu zuwa tsarin infotainment, ya zama dole a yi haɗin gwiwar hannu don kowace na'ura.Koyaya, ta hanyar haɗa cajin mara waya ta Qi tare da sadarwar NFC, Rohm ya ba da damar ba kawai cajin na'urorin hannu kamar wayoyi ba, har ma da yin haɗin Bluetooth ko Wi-Fi lokaci guda ta hanyar tantancewar NFC.

ST25R3914/3915 mai karatu na mota NFC ICs sun dace da ISO14443A/B, ISO15693, FeliCa, da ISO18092 (NFCIP-1) P2P mai aiki.Suna haɗa ƙarshen gaban analog wanda ke nuna abin da ake iƙirarin zama mafi kyawun ji na mai karɓa, yana ba da aikin gano abu na waje a cikin na'urorin haɗi na cibiyar abin hawa.Dangane da ma'aunin Qi, an haɗa aikin gano abu na waje don gano abubuwan ƙarfe.Wannan yana hana nakasawa ko lalacewa faruwa saboda yawan zafin da ake samu a yayin da aka sanya wani abu mai ƙarfe tsakanin mai watsawa da mai karɓa.

ST25R3914 ya haɗa da aikin ST’s na mallakar ta atomatik Antenna Tuning.Yana dacewa da canje-canjen muhallin da ke kewaye don rage tasirin abubuwa na ƙarfe kusa da eriyar mai karatu, kamar maɓalli ko tsabar kuɗi da aka sanya akan na'ura mai kwakwalwa ta tsakiya.Bugu da ƙari, MISRA-C: 2012-compliant RF middleware yana samuwa, wanda ke taimaka wa abokan ciniki su rage ƙoƙarin haɓaka software.

STM8A na kera motoci 8-bit MCU ya zo cikin fakiti iri-iri da girman ƙwaƙwalwar ajiya.Ana kuma bayar da na'urorin da ke da bayanan EEPROMs, gami da samfuran CAN waɗanda ke nuna tsawaita kewayon zafin aiki wanda aka tabbatar da shi har zuwa 150°C, yana sa su dace da aikace-aikacen kera iri-iri.
