Lub vev xaib no yog ua haujlwm los ntawm kev lag luam lossis kev lag luam uas muaj los ntawm Informa PLC thiab txhua qhov kev cai lij choj nyob nrog lawv.Informa PLC lub chaw ua haujlwm sau npe yog 5 Howick Place, London SW1P 1WG.Sau npe hauv England thiab Wales.ib 8860726.
Rohm tau tshaj tawm txoj kev txhim kho ntawm lub tsheb wireless-them kev daws teeb meem nrog kev sib txuas lus nyob ze (NFC).Nws sib koom ua ke Rohm's automotive-qib (AEC-Q100 tsim nyog) wireless fais fab kis tswj IC (BD57121MUF-M) nrog STMicroelectronics 'NFC Reader IC (ST25R3914) thiab 8-ntsis microcontroller (STM8A series).
Ntxiv nrog rau kev ua raws li WPC's Qi tus qauv txhawb nqa EPP (Ntev Cov Hluav Taws Xob Profile), uas ua rau lub charger muab tau txog li 15 W ntawm lub zog, ntau lub kauj tsim tau hais kom ua kom muaj ntau qhov chaw them nyiaj (2.7X ntau dua them ntau dua piv rau. ib coil configurations).Qhov no txhais tau hais tias cov neeg siv khoom yuav tsum tsis txhob txhawj xeeb txog kev ua raws nraim li lawv cov smartphones mus rau qhov chaw them nyiaj kom tuaj yeem them wirelessly.
Qi wireless charging tau txais los ntawm European Automotive Standards Group (CE4A) ua tus qauv them nyiaj hauv tsheb.Los ntawm 2025, nws tau kwv yees tias feem ntau lub tsheb yuav nruab nrog Qi-based wireless chargers.
NFC muab kev lees paub rau cov neeg siv kom tso cai rau kev sib txuas lus Bluetooth / Wi-Fi nrog cov infotainment units, lub qhov rooj xauv / xauv lub tshuab, thiab lub cav pib.NFC tseem tso cai rau kev teeb tsa lub tsheb rau ntau tus neeg tsav tsheb, xws li lub rooj zaum thiab daim iav qhov chaw, infotainment pre-sets, thiab navigation lo lus uas peb pre-sets.Hauv kev ua haujlwm, lub xov tooj smartphone tau muab tso rau ntawm lub ncoo them nyiaj kom pib qhov screen sib koom nrog cov infotainment thiab navigation system.
Yav dhau los, thaum txuas smartphones rau infotainment systems, nws yog ib qho tsim nyog yuav tau ua phau ntawv khub rau txhua lub cuab yeej.Txawm li cas los xij, los ntawm kev sib txuas Qi wireless charging nrog NFC kev sib txuas lus, Rohm tau ua kom tsis yog tsuas yog them cov khoom siv mobile xws li smartphones, tab sis kuj ua Bluetooth lossis Wi-Fi ua ke ib txhij los ntawm NFC authentication.
ST25R3914/3915 automotive-qib NFC nyeem ntawv ICs tau tshaj ISO14443A/B, ISO15693, FeliCa, thiab ISO18092 (NFCIP-1) Active P2P.Lawv suav nrog qhov sib piv hauv ntej kawg uas muaj qhov uas tau lees tias yog qhov zoo tshaj plaws-hauv-chav kawm tau txais kev nkag siab zoo, xa cov khoom txawv teb chaws nrhiav kev ua tau zoo hauv lub tsheb nruab nrab consoles.Raws li tus qauv Qi, muaj cov khoom siv txawv teb chaws nrhiav kom pom cov khoom siv hlau.Qhov no tiv thaiv kev deformation lossis kev puas tsuaj los ntawm qhov tshwm sim vim muaj cua sov ntau dhau thaum cov khoom siv hlau raug muab tso rau ntawm lub transmitter thiab receiver.
ST25R3914 suav nrog ST's proprietary Automatic Antenna Tuning muaj nuj nqi.Nws hloov mus rau ib puag ncig kev hloov pauv kom txo qis qhov cuam tshuam los ntawm cov khoom siv hlau nyob ze ntawm tus nyeem ntawv kav hlau txais xov, xws li cov yuam sij lossis npib tso rau ntawm qhov chaw nruab nrab.Tsis tas li ntawd, MISRA-C: 2012-raws li RF nruab nrab yog muaj, uas pab cov neeg siv khoom txo lawv cov software-tsim kev siv zog.
STM8A automotive 8-ntsis MCU series los ntawm ntau pob thiab nco qhov ntau thiab tsawg.Cov khoom siv nrog cov ntaub ntawv EEPROMs kuj muaj, suav nrog CAN-ntaus qauv uas muaj kev ua haujlwm ntev ntev tau lees paub txog 150 ° C, ua rau lawv zoo rau ntau yam kev siv tsheb.
