Rohm Isku Dallacaadaha Wireless Automotive iyo NFC

Mareegtan waxaa maamula ganacsi ama meherado ay leedahay Informa PLC oo dhammaan xuquuqda daabacaada ayaa iyaga la nool.Informa PLC xafiiskeeda ka diiwaan gashan waa 5 Howick Place, London SW1P 1WG.Ka diiwaan gashan England iyo Wales.Lambarka 8860726.

Rohm waxa uu ku dhawaaqay in la sameeyay xal ku dallacaadda wireless-ka baabuurta oo leh isgaarsiin meel u dhow oo isku dhafan (NFC).Waxay isku daraysaa Rohm's automotive-grade (AEC-Q100 qualified) kontoroolka gudbinta korantada wireless IC (BD57121MUF-M) iyo STMMicroelectronics' NFC Reader IC (ST25R3914) iyo 8-bit microcontroller (STM8A series).

Marka lagu daro u hoggaansanaanta heerka WPC ee Qi ee taageeraya EPP (Extend Power Profile), kaas oo awood u siinaya dabeysha inuu bixiyo ilaa 15 W oo koronto ah, naqshadeynta gariiradda badan ayaa la sheegay inay awood u siiso aag dallacaad ballaaran qaabaynta gariiradda hal mar).Tani waxay ka dhigan tahay in macaamiishu aysan u baahnayn inay ka werweraan inay si sax ah u waafajiyaan taleefanadooda casriga ah goobta lagu dallaco si ay awood ugu yeeshaan inay ku dallacaan wireless-ka.

Ku dallacaadda wireless-ka ee Qi waxa qaatay Kooxda Heerarka Baabuurta ee Yurub (CE4A) sidii heerka dallacaadda baabuurta.Marka la gaaro 2025, waxaa la saadaaliyay in baabuurta intooda badan lagu qalabayn doono dabaysha wireless-ka ee ku salaysan Qi.

NFC waxay siisaa aqoonsiga isticmaalaha si ay ugu ogolaato xidhiidhka Bluetooth/Wi-Fi ee qaybaha xogta, qufulka albaabka/nidaamka furitaanka, iyo bilaabista mishiinka.NFC waxa kale oo ay awood u siisaa habaynta gaadhiga loo habeeyay darawalo badan, sida fadhiga iyo meelaynta muraayada, xog-u-dhigista hore-u-dhigista, iyo meelaynta meelaynta.Marka uu shaqaynayo, talefanka casriga ah ayaa la dhigayaa suufka dallacaadda si uu si toos ah u bilaabo wadaagista shaashadda ee macluumaadka iyo nidaamka hagidda.

Markii hore, marka lagu xidho taleefannada casriga ah nidaamyada macluumaadka, waxay ahayd lagama maarmaan in la sameeyo isku-duubnida gacanta ee qalab kasta.Si kastaba ha noqotee, isku darka dallacaadda wireless-ka ee Qi iyo isgaarsiinta NFC, Rohm wuxuu suurtageliyay in aan lagu dallacin oo keliya aaladaha mobilada sida taleefannada casriga ah, laakiin sidoo kale la sameeyo isku-xirnaanta Bluetooth ama Wi-Fi iyada oo loo marayo aqoonsiga NFC.

ST25R3914/3915 baabuurta NFC akhristaha ICs waxay la jaan qaadayaan ISO14443A/B, ISO15693, FeliCa, iyo ISO18092 (NFCIP-1) P2P firfircoon.Waxay ku daraan dhamaadka hore ee analooga ah oo muujinaya waxa la sheegay in uu yahay dareenka qaataha heerka ugu wanaagsan, oo soo bandhigaya waxqabadka sheyga shisheeyaha ee consoles-yada xarunta baabuurta.Marka la eego halbeegga Qi, shaqada ogaanshaha shay shisheeye ee lagu ogaanayo walxaha macdan ayaa ku jira.Tani waxay ka hortagtaa qallafsanaan ama dhaawac inay ku dhacaan kuleyl xad dhaaf ah oo abuurmaya haddii ay dhacdo shay macdan la dhex dhigo gudbiyaha iyo qaataha.

ST25R3914 waxa ku jira shaqada STâ€TMs ee Atoomatiga ah ee Antenna Tuning.Waxay la qabsataa isbeddellada ku xeeran deegaanka si ay u yarayso saamaynta walxaha macdan ah ee u dhow anteenada akhristaha, sida furayaasha ama qadaadiicda lagu dhejiyo konsole dhexe.Intaa waxaa dheer, MISRA-C: 2012-ku-qanacsanaanta RF dhexe waa la heli karaa, taas oo ka caawisa macaamiisha inay yareeyaan dadaalkooda horumarinta software.

Taxanaha STM8A automotive 8-bit MCU wuxuu ku yimaadaa baakado kala duwan iyo cabbirrada xusuusta.Aaladaha ay ku jiraan xogta EEPROM-yada ayaa sidoo kale la bixiyaa, oo ay ku jiraan moodooyinka ku qalabaysan CAN oo muujinaya dhererka heerkulka hawlgalka ee la dheereeyay ee dammaanad qaadaya ilaa 150°C, taasoo ka dhigaysa inay si fiican ugu habboon yihiin codsiyada baabuurta kala duwan.
