Uru rubuga rukoreshwa nubucuruzi cyangwa ubucuruzi bufitwe na Informa PLC kandi uburenganzira bwose bubana nabo.Ibiro bya Informa PLC byanditse ni 5 Howick Place, London SW1P 1WG.Yiyandikishije mu Bwongereza na Wales.Numero 8860726.
Rohm yatangaje ko hazashyirwaho igisubizo cy’imodoka idafite amashanyarazi-yishyurwa hamwe n’itumanaho ryegereye umurima (NFC).Ihuza hamwe na Rohm yo mu rwego rwo gutwara ibinyabiziga (AEC-Q100 yujuje ibyangombwa) igenzura amashanyarazi adafite amashanyarazi IC (BD57121MUF-M) hamwe na STMicroelectronics 'NFC Umusomyi IC (ST25R3914) na microcontroller (biti ya STM8A).
Usibye kuba wujuje ubuziranenge bwa WPC Qi ushyigikira EPP (Kwagura Umwirondoro Wimbaraga), ituma charger itanga amashanyarazi agera kuri 15 W, igishushanyo mbonera cya coil bivugwa ko gishobora gutuma ahantu hanini ho kwishyuza (2.7X nini yo kwishyuza hamwe na ibishushanyo bimwe).Ibi bivuze ko abaguzi badakeneye guhangayikishwa no guhuza neza na terefone zabo n’ahantu hateganijwe kwishyurwa kugirango babashe kwishyuza mu buryo butemewe.
Qi kwishyuza bidasubirwaho byemejwe nitsinda ry’iburayi ry’ibinyabiziga (CE4A) nk'urwego rwo kwishyuza mu binyabiziga.Kugeza mu 2025, byahanuye ko imodoka nyinshi zizaba zifite ibikoresho bya Qi bishingiye ku mashanyarazi.
NFC itanga ibyemezo byabakoresha kugirango yemere itumanaho rya Bluetooth / Wi-Fi hamwe namakuru ya infotainment, sisitemu yo gufunga / gufungura sisitemu, na moteri itangira.NFC kandi ituma ibinyabiziga byabugenewe byabigenewe kubashoferi benshi, nkicyicaro hamwe nindorerwamo, infotainment ibanziriza-seti, hamwe nogushaka kugana mbere.Mubikorwa, terefone ishyirwa kumashanyarazi kugirango ihite itangira kugabana ecran hamwe na sisitemu ya infotainment na nogisi.
Mbere, mugihe uhuza terefone zigendanwa na sisitemu ya infotainment, byari ngombwa gukora intoki kuri buri gikoresho.Ariko, muguhuza Qi itishyurwa itishyurwa hamwe nitumanaho rya NFC, Rohm yatumye bishoboka ko utishyuza gusa ibikoresho bigendanwa nka terefone zigendanwa, ahubwo unakora Bluetooth cyangwa Wi-Fi icyarimwe binyuze mubyemezo bya NFC.
ST25R3914 / 3915 yimodoka yo mu rwego rwa NFC abasomyi IC irahuza na ISO14443A / B, ISO15693, FeliCa, na ISO18092 (NFCIP-1) Active P2P.Bashyizemo impera yimbere igereranya ibyo bavugaga ko ari byiza-mu byiciro byakira neza ibyiyumvo, bitanga imikorere-yo gutahura ibintu-mumahanga muri kanseri yikigo.Kuri Qi isanzwe, ibikorwa byamahanga byo gutahura ibikorwa byo gutahura ibintu byuma birimo.Ibi birinda guhindura cyangwa kwangirika kubaho bitewe nubushyuhe bukabije mugihe habaye ikintu cyuma gishyizwe hagati ya transmitter niyakira.
ST25R3914 ikubiyemo imikorere yihariye ya Automatic Antenna Tuning.Ihuza nibidukikije bihindagurika kugirango igabanye ingaruka ziva mubintu byuma hafi ya antenna yabasomyi, nkurufunguzo cyangwa ibiceri byashyizwe kumurongo wa kanseri.Mubyongeyeho, MISRA-C: 2012-yujuje ibyangombwa byo hagati ya RF irahari, ifasha abakiriya kugabanya imbaraga zabo zo guteza imbere software.
Imodoka ya STM8A 8-bit MCU ikurikirana iza mubipaki bitandukanye nubunini bwa memoire.Ibikoresho bifite amakuru yashyizwemo EEPROM nayo iratangwa, harimo na moderi ifite ibikoresho bya CAN yerekana ubushyuhe bwagutse bwo gukora bwijejwe kugera kuri 150Â ° C, bigatuma bikwiranye nibikorwa bitandukanye byimodoka.
