I-St Microelectoronics iqala inzwa ye-S-Thinta nge-Atlab Capacitive Touch Sensing Technology

Izindaba ze-Screen Screen Screen Screen, ama-Stmicroelectonics wethula ngokusemthethweni uchungechunge lwezinzwa ezintsha ze-S-touch. Ama-Stmicroelectoronics akhiphe uchungechunge lwama-Ultra-Low Power Son Snen Sensor chips ngemuva kokusayina isivumelwano selayisense lobuchwepheshe nenkampani yaseNingizimu Korea Inkampani ye-ATLAB. Izicelo ezihlosiwe zochungechunge olusha lwemikhiqizo zingamadivayisi aphathekayo njengezingcingo eziphathwayo, amakhompiyutha e-PDA, amakhompiyutha encwajana nabadlali bemidiya, kanye nemakethe yezimpahla ezimhlophe ezibucayi. Izinzwa ezintsha ze-S-Touch Secors zamukele ubuchwepheshe be-Atlab's Capacive Touch Technology, okususelwa kwi-The Absitecture yedijithali yansuku zonke futhi kulawula isikhombimsebenzisi sokusebenza esiphendula ekuthinteni komsebenzisi, i-Chip-Chip Microcontroller, inkumbulo, noma i-firmware iyadingeka. Imikhiqizo yokuqala kulolu chungechunge yizinzwa zesiteshi esineziteshi eziyi-8 kanye nezinkulungwane eziyi-12.
Lo mkhiqizo we-HardWired Sensor Sensor Sensor uwukungezelelwa okuwusizo ku-ST esuselwa ku-QTI CECIPE ESETSHEKILE. Izicelo eziyinkimbinkimbi ezingabona i-interface yokulawula inzwa yokuxhumana ye-QT, ngakolunye uhlangothi, ama-micrococtoctollers ngaphakathi kwalezi zinzwa angalawula nemisebenzi eminingi esetshenziswayo kwimikhiqizo elula. I-ST ine-Securies emibili yePothifolio yemikhiqizo ye-Sensor ngasikhathi sinye, futhi kuwukuphela komenzi emakethe ye-semiconductor enganikeza izixazululo zezinzwa eziphelele zokuhlangabezana nezidingo zohlelo lokusebenza.
I-ST ibeka umshini wombuso onzima wombuso onzima ekulinganiseni izinzwa ze-S-Touch Securies. Ubuchwepheshe obusetshenzisiwe be-silicon obusetshenzisiwe budinga amandla aphansi kakhulu: ukusetshenziswa kwamandla cishe ku-1/5 kuya kulokho okuvamile kwe-touch sensor solution, futhi ukusetshenziswa kwamandla kwimodi yokulala kungu-1 microampere angu-1 microampere. Umugqa oxhumanisa inzwa nethaye le-TouchPad yedivayisi yokusebenzisa ayidingi inethiwekhi yokumelana yangaphandle, kanti ezinye izixazululo ze-SensOR zivame ukudinga inethiwekhi yokumelana ne-capacitance. Ubukhulu balezi zinzwa buncane kakhulu. Umkhiqizo wokufaka we-8-Way uhlanganiswe kwiphakheji le-2.6x1.8 QFN16, elicishe libe ngama-80% amancane kunekhambi elilinganayo futhi linokuncintisana okuphezulu kakhulu. Isikhathi sokusampula salolu chungechunge lwezinzwa ngama-millissecond ama-2, okuwumkhiqizo osheshayo emakethe.
Imikhiqizo yesikhathi esizayo izophinde ihlanganise ubuchwepheshe obunelungelo lobunikazi kumikhiqizo emisha ye-Xpander ENTSHA ENTSHA YOKUTHOLA I-I / O e-Ultra-Low Power XPander Logic IC, lobu buchwepheshe busiza ukunqoba izinqubo zokufaka kanye nokukhipha zikhawulelwe kuzinhlelo ezishukiwe ze-MCU. Lobu buchwepheshe bunika amandla amaprosesa akhona akhona ukusebenzisa i-interface ehlukahlukene ehlakaniphile ngokusebenzisa isikhombimsebenzisi esisheshayo se-I2C, kufaka phakathi izilawuli zekhibhodi esekela kuze kufike ezinkahluyo ezingama-96, umsebenzi okhiye we-Ghost kanye ne-LED Brightness) nge-PWM (Pulse I-Modaution).
Ngokuhlanganisa i-ST ne-ATLAB's IP (I-Preyince Property) Ngale ndlela, i-S-touch izokwazi ukubona isixazululo se-monolithic esisebenza ngokugcwele somsebenzisi, singaphatha ikhibhodi ejwayelekile yokulawula ikhibhodi kanye nokhiye wokuhambisa i-LED backlight control ukhiye kanye nokhiye wokuthinta waseCapacide. I-St futhi ihlela ukuhlola ngamathuba we-Atlab ukuqinisa ukubambisana ezindaweni ezithuthukisiwe ze-IP Design Design emikhakheni ethile. Lobu buchwepheshe bungezezelwa emikhiqizweni yochungechunge lwe-QT Countcrontroller olususelwa ku-ST, oluqinisekisa ukuhlinzeka amakhasimende ngezinqumo zokuqamba zezinzwa, ahlangabezane nezidingo zezitayela ezahlukene zomkhiqizo, izinto zokwakha kanye nemisebenzi.
