Rohm e Kopanya ho tjhaja Waelese ea Likoloi le NFC

Sebaka sena sa marang-rang se tsamaisoa ke khoebo kapa likhoebo tsa Informa PLC mme litokelo tsohle tsa litokelo li lula ho tsona.Ofisi e ngolisitsoeng ea Informa PLC ke 5 Howick Place, London SW1P 1WG.E ngolisitsoe Engelane le Wales.Nomoro 8860726.

Rohm e phatlalalitse nts'etsopele ea tharollo ea ho tjhaja waelese ea likoloi ka puisano e kopaneng ea haufi le lebala (NFC).E kopanya IC (BD57121MUF-M) ea Rohm's automotive-grade (AEC-Q100 qualified) le IC (BD57121MUF-M) le STMicroelectronics' NFC Reader IC (ST25R3914) le 8-bit microcontroller (STM8A series).

Ntle le ho lumellana le maemo a WPC a Qi a tšehetsang EPP (Eketsa Power Profile), e nolofalletsang tjhaja ho fana ka matla a fihlang ho 15 W, moralo oa li-coil tse ngata o boleloa o thusa sebaka se pharaletseng sa ho tjhaja (2.7X e kholo ea ho tjhaja ha e bapisoa le mefuta e mengata ea tjhaja. tlhophiso ea khoele e le 'ngoe).Sena se bolela hore bareki ha baa lokela ho tšoenyeha ka ho hokahanya li-smartphone tsa bona sebakeng se fanoeng sa ho tjhaja hore ba tsebe ho tjhaja ntle le waelese.

Ho tjhaja waelese ka Qi ho amohetswe ke European Automotive Standards Group (CE4A) e le tekanyetso ya ho tjhaja dikoloi.Ka 2025, ho lebeletsoe esale pele hore likoloi tse ngata li tla ba le li-charger tse thehiloeng ho Qi.

NFC e fana ka netefatso ea mosebelisi ho lumella puisano ea Bluetooth/Wi-Fi ka likarolo tsa infotainment, senotlolo sa mamati/notlolo, le ho qala enjene.NFC e boetse e thusa litlhophiso tsa likoloi tse ikhethileng bakeng sa bakhanni ba bangata, joalo ka boemo ba litulo le seipone, li-pre-sets tsa infotainment, le li-pre-sets tsa sebaka seo u eang ho sona.Ha e ntse e sebetsa, smartphone e behoa sebakeng sa ho tjhaja ho qala ka bo eona ho arolelana skrini le sistimi ea infotainment le navigation.

Nakong e fetileng, ha o hokahanya li-smartphone le lits'ebetso tsa infotainment, ho ne ho hlokahala ho etsa pairing ea matsoho bakeng sa sesebelisoa ka seng.Leha ho le joalo, ka ho kopanya ho tjhaja waelese oa Qi le likhokahano tsa NFC, Rohm e entse hore ho khonehe hore e se ke ea lefisa lisebelisoa tsa mohala feela joalo ka li-smartphone, empa hape le ho kopanya Bluetooth kapa Wi-Fi ka nako e le 'ngoe ka netefatso ea NFC.

Li-IC tsa ST25R3914/3915 tsa sehlopha sa likoloi tsa NFC li lumellana le ISO14443A/B, ISO15693, FeliCa, le ISO18092 (NFCIP-1) Active P2P.Li kenyelletsa karolo e ka pele ea analog e nang le seo ho thoeng ke seamoheli se maemong a holimo, se fanang ka ts'ebetso ea ho lemoha lintho tse tsoang kantle ho li-consoles tsa bohareng ba likoloi.Ho latela maemo a Qi, ho kenyelelitsoe tšebetso ea ho lemoha ntho e tsoang kantle ho naha bakeng sa ho lemoha lintho tsa tšepe.Sena se thibela ho senyeha kapa ho senya ho etsahala ka lebaka la ho hlahisa mocheso o feteletseng haeba ntho ea tšepe e behoa pakeng tsa transmitter le receiver.

ST25R3914 e kenyelletsa ts'ebetso ea Automatic Antenna Tuning ea ST.E ikamahanya le liphetoho tsa tikoloho ho fokotsa litlamorao tse tsoang linthong tsa tšepe tse haufi le antenna, joalo ka linotlolo kapa lichelete tsa tšepe tse behiloeng bohareng ba console.Ho feta moo, MISRA-C: 2012-compliant RF middleware e teng, e thusang bareki ho fokotsa boiteko ba bona ba ho ntlafatsa software.

Letoto la STM8A la likoloi tsa 8-bit MCU le tla ka liphutheloana tse fapaneng le boholo ba memori.Ho boetse ho fanoa ka lisebelisoa tse nang le lintlha tse kentsoeng tsa EEPROM, ho kenyeletsoa mefuta e nang le CAN e nang le mocheso o atolositsoeng oa ts'ebetso o netefalitsoeng ho fihla ho 150°C, e leng se etsang hore li lokele mefuta e fapaneng ea lits'ebetso tsa likoloi.
