STM32L072CBT6 IC MCU 32BIT 128KB FLASH 48LQFP

Ibisobanuro

Ultra-low-power-STM32L072xx 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 STM32L072xx bitanga imbaraga zingirakamaro kubikorwa byinshi.Byagerwaho hamwe nuguhitamo gukomeye kwimbere nimbere yo hanze yisoko, imihindagurikire yimbere yimbere hamwe nuburyo buke buke.Ibikoresho bya STM32L072xx 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-bigamije 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 STM32L072xx byashyizemo imiyoboro y'itumanaho isanzwe kandi igezweho: kugeza kuri I2Cs eshatu, SPI ebyiri, imwe I2S, USARTs enye, UART ifite ingufu 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.STM32L072xx nayo ikubiyemo isaha nyayo hamwe nuruhererekane rwibitabo byabigenewe bikomeza gukoreshwa muburyo bwa standby.Ibikoresho bya ultra-low-power STM32L072xx ikora kuva kuri 1.8 kugeza kuri 3.6 V itanga amashanyarazi (kumanuka kugeza kuri 1.65 V kumashanyarazi) hamwe na BOR no kuva kuri 1.65 kugeza 3.6 V itanga amashanyarazi nta BOR ihitamo.Baraboneka muri -40 kugeza kuri +125 ° C.Uburyo bwuzuye bwo kuzigama imbaraga butuma igishushanyo mbonera cyingufu zikoreshwa
