STM32L073RBT6 IC MCU 32BIT 128KB FLASH 64LQFP

Ibisobanuro

Ultra-low-power-STM32L073xx microcontrollers ikubiyemo imbaraga zo guhuza bisi ya serial yisi yose (USB 2.0 kristal-nkeya) hamwe na Arm Cortex-M0 + 32-bit ya RISC ikora cyane kuri 32 MHz, ishami ririnda kwibuka ( MPU), ibintu byihuta byashyizwemo kwibuka (bigera kuri 192 Kbytes ya porogaramu ya Flash ya porogaramu, Kbytes 6 zamakuru EEPROM na 20 Kbytes ya RAM) hiyongereyeho intera nini ya I / Os hamwe na peripheri.Ibikoresho bya STM32L073xx bitanga imbaraga zingirakamaro kubikorwa byinshi.Byagerwaho hamwe nuguhitamo gukomeye kwimbere nimbere yo hanze yisoko, imihindagurikire yimbere yimbere hamwe nuburyo buke buke.Ibikoresho bya STM32L073xx bitanga ibintu byinshi bisa, kimwe 12-biti ADC hamwe nibikoresho birenze urugero, DAC ebyiri, igereranya-ultra-nke-igereranya, igihe kinini, igihe gito-gito (LPTIM), bine rusange-intego-16-biti na bibiri igihe cyibanze, RTC imwe na SysTick imwe ishobora gukoreshwa nkigihe cyagenwe.Bagaragaza kandi indorerezi ebyiri, umurinzi umwe ufite isaha yigenga nubushobozi bwidirishya hamwe nidirishya rimwe rishingiye kumasaha ya bisi.Byongeye kandi, ibikoresho bya STM32L073xx byashyizemo imiyoboro y'itumanaho isanzwe kandi igezweho: kugeza kuri I2Cs, SPI ebyiri, imwe I2S, USARTs enye, UART ifite imbaraga nke (LPUART), na USB idafite kristu.Ibikoresho bitanga imiyoboro igera kuri 24 yerekana ubushobozi bwo kongeramo imikorere yo gukoraho kuri porogaramu iyo ari yo yose.STM32L073xx nayo ikubiyemo isaha-nyayo hamwe nuruhererekane rwibitabo byabigenewe bikomeza gukoreshwa muburyo bwa standby.Hanyuma, umugenzuzi wabo wa LCD afite ibyuma byubaka amashanyarazi ya LCD yemerera gutwara LCDs zigera kuri 8 zitandukanye kandi bitandukanye na voltage itangwa.Ibikoresho bya ultra-low-power STM32L073xx ikora kuva kuri 1.8 kugeza kuri 3.6 V itanga amashanyarazi (kumanuka kugeza kuri 1.65 V kumanuka) hamwe na BOR no kuva kuri 1.65 kugeza kuri 3.6 V amashanyarazi nta BOR ihitamo.Baraboneka muri -40 kugeza kuri +125 ° C.Uburyo bwuzuye bwo kuzigama imbaraga butuma igishushanyo mbonera cyingufu zikoreshwa.
