I-8 Bit kanye ne-32 Bit Microcontrollers
UMHLAHLANDLELA WOKUKHETHA WE-MCU WE-IOT
I-8-bit kanye ne-32-bit Microcontrollers
Izwa Ukufuduka Okulula Ukuya Ekuxhumaneni Okungenantambo Ngamandla Aphansi Kakhulu, Ama-MCU Asebenza Kakhulu
Ama-Microcontrollers (MCUs) awumgogodla wamadivayisi e-IoT, ahlinzeka ngamandla okucubungula nokusebenza okudingekayo kuyo yonke into kusukela kumadivayisi ahlakaniphile asekhaya kuya ezintweni ezigqokwayo nemishini yezimboni eyinkimbinkimbi. Zivame ukucatshangwa njengobuchopho bemishini nezinhlelo eziningi, okwenza ngokusobala zibe ezinye zezingxenye ezibaluleke kakhulu.
Lapho ukhetha amaphrosesa, abenzi bedivayisi bavame ukufuna usayizi omncane, ukufinyeleleka, kanye nokusetshenziswa kwamandla okuphansi - okwenza ama-MCU abe imbangi ecacile. Ngaphezu kwalokho, bangenza ukulawula kwedijithali kwamadivayisi nezinqubo kusebenze ngokunciphisa usayizi nezindleko
uma kuqhathaniswa nemiklamo ebiza ama-microprocessors ahlukene nezinkumbulo.
Ukukhethwa kweplatifomu yephrosesa efanele kubalulekile. Noma ngabe ufuna ukwakha amadivayisi axhunyiwe noma angaxhumekile, ufike endaweni efanele. Yonke imikhiqizo ye-Silicon Labs isekelwe ku-MCU, ngakho-ke singathembisa ukwethembeka nokusebenza kahle kwabenzi bedivayisi kulo lonke uhlelo lokusebenza uma sinikezwe isipiliyoni seminyaka yethu.
Iphothifoliyo ye-MCU ye-Silicon Labs iqukethe imindeni emibili ye-MCU, ngayinye isebenzela injongo ethile:
I-Silicon Labs 32-bit MCUs
Izinzwa zamandla, izici ezithuthukisiwe
I-Silicon Labs 8-bit MCUs
Zonke izinto ezibalulekile, zilula ngentengo
Iphothifoliyo ye-MCU ye-Silicon Labs
Iphothifoliyo yethu ye-MCU yakhelwe phezu kwesisekelo somklamo womsakazo kanye nomlando wokuqanjwa kabusha kwezobuchwepheshe. I-Silicon Labs inikeza kokubili i-8-bit kanye ne-32-bit MCUs, eklanyelwe ukuhlangabezana nezidingo ezihlukahlukene zezinhlelo zokusebenza zesimanje ze-IoT njengesixazululo sokuma okukodwa sokuthuthukiswa kwezinhlelo zokusebenza ezinezintambo nezingenantambo.
Ngokufinyelela okusheshayo kuzinsiza zikanjiniyela ezaziwayo kakade, inkundla yethu inikeza ukugcwaliswa okuphelele kwamandla aphansi, ama-microcontrollers anesivinini esikhulu, amakhithi okuthuthukisa, ama-ex akhethekile.ample code, namandla okulungisa athuthukile, kanye nokuthuthela kalula ekusebenzeni okungenantambo kuzo zonke izivumelwano.
Womabili ama-MCU angu-8-bit kanye nama-32-bit abhekana nezinselele ezihlukile futhi anendawo ekuthuthukisweni kwesimanje kwe-IoT.

Ama-MCU angu-32-bit: Isakhiwo Samandla Aphansi
Imindeni ye-Silicon Labs' EFM32 32-bit MCU iyizilawuli ezincane ezisebenziseka kalula emhlabeni, ezifanele ikakhulukazi ukusetshenziswa kuzinhlelo zokusebenza ezizwelayo namandla aphansi, okuhlanganisa amandla, amanzi, nokulinganisa kwegesi, ezishintshayo zokwakha, i-alamu nokuphepha, kanye nemishini yezokwelapha/yokufaneleka ephathekayo.
Njengoba ukushintshwa kwebhethri ngokuvamile kungenzeki ngenxa yezizathu zokufinyelela nezindleko, izinhlelo ezinjalo zidinga ukusebenza isikhathi eside ngangokunokwenzeka ngaphandle kwamandla angaphandle noma ukungenelela komsebenzisi.
Ngokusekelwe ku-ARM® Cortex® -M0+, Cortex-M3, Cortex-M4 kanye ne-Cortex-M33 cores, ama-MCU ethu angu-32-bit andisa impilo yebhethri kulabo “okunzima ukufinyelela kuzo”, izinhlelo zokusebenza zabasebenzisi ezizwela amandla nezimboni.

Yini Ehlukanisa I-32-bitPortfolio yethu
I-Low Power Architecture
Ama-EFM32 MCU afaka ama-ARM Cortex® cores aneyunithi yephoyinti elintantayo nememori ye-Flash futhi akhelwe amandla aphansi kusetshenziswa kuphela okungu-21 µA/MHz kumodi esebenzayo. Amadivayisi adizayinelwe ukukala amandla okusetshenziswa ngamandla ngamamodi amane wamandla, okuhlanganisa imodi yokulala ejulile ephansi njengo-1.03 µA, enokugcinwa kwe-RAM okungu-16 kB kanye newashi lesikhathi sangempela elisebenzayo, kanye nemodi yokulala engu-400 nA enamabhayithi angu-128 okugcinwa kwe-RAM nesibali-sikhathi se-cryo.
Amathuluzi Angcono Kakhulu Ekilasini
I-OS eshumekiwe, izitaki zesofthiwe yokuxhumana, ama-IDE namathuluzi okuthuthukisa idizayini - konke kusendaweni eyodwa.I-RTOS ehamba phambili embonini enosekelo lwamahhala lwe-kernel IDE ye-Keil, IAR kanye namathuluzi e-GCC ukuze kuthuthukiswe imiklamo ngezici ezivumela izenzo ezifana nokuprofetha kokusetshenziswa kwamandla nokubonwa kalula kwangaphakathi kwanoma iyiphi isistimu eshumekiwe.
Ukuphepha Ukumelana Nokuhlasela Okuyinselele Kakhulu
Ukubethela kuqine kuphela njengesivikelo esinikezwa idivayisi ebonakalayo ngokwayo. Ukuhlasela kwedivayisi okulula kakhulu ukuhlasela okukude kwesofthiwe ukuze kujove uhlelo olungayilungele ikhompuyutha yingakho impande yezingxenyekazi zekhompuyutha ye-trust evikelekile yokuqalisa ibalulekile.
Amadivayisi amaningi e-IoT atholakala kalula ku-supply chain futhi avumela ukuhlaselwa kwe-“Hands-On” noma “Local”, okuvumela ukuhlasela imbobo yokulungisa iphutha noma ukusebenzisa ukuhlasela okuphathekayo njengokuhlaziywa kwesiteshi eseceleni ukuze kubuyiselwe okhiye phakathi nokubethelwa kokuxhumana.
Thembela ubuchwepheshe be-Silicon Labs buzovikela ubumfihlo bamakhasimende akho kungakhathaliseki ukuthi hlobo luni lokuhlaselwa.
Ukuminyana Okusebenzayo Kokunciphisa Izindleko
Ama-microprocessors adidiyelwe kakhulu aqhosha ngokukhethwa okucebile kokusebenza okuphezulu okutholakalayo kanye nama-peripherals atholakalayo ku-chip non-volatile memory, imilobo yenkumbulo ebukhali, isibali sikhathi sokulala esingamakristalu esingu-500 ppm, nemisebenzi edidiyelwe yokuphatha amandla.
Mayelana ne-Silicon Labs
I-Silicon Labs ingumhlinzeki oholayo we-silicon, isofthiwe, nezixazululo zomhlaba ohlakaniphile, oxhumeke kakhulu. Izixazululo zethu ezingenazintambo ezihamba phambili embonini zifaka izinga eliphezulu lokuhlanganisa okusebenzayo. Imisebenzi eminingi eyinkimbinkimbi yamasignali ahlanganisiwe ihlanganiswe ku-IC eyodwa noma idivayisi ye-system-on-chip (SoC), konga indawo enenani, kuncishiswe zonke izidingo zokusetshenziswa kwamandla, nokuthuthukisa ukwethembeka kwemikhiqizo. Singozakwethu abathembekile kubathengi abahamba phambili nemikhiqizo yezimboni. Amakhasimende ethu athuthukisa izixazululo zezinhlelo zokusebenza ezihlukene, kusukela kumishini yezokwelapha kuya ekukhanyeni okuhlakaniphile kuye ezishintshayo zokwakha, nokunye okuningi.
