♠ Ultra-low-power 32-bit MCU Arm® ishingiye kuri Cortex®-M0 +, kugeza Flash ya 192KB, 20KB SRAM, 6KB EEPROM, USB, ADC, DACs
Ultra-low-power-STM32L072xx microcontrollers ikubiyemo imbaraga zo guhuza zabisi ya serial rusange (USB 2.0 kristal-nkeya) hamwe na Arm Cortex-M0 + ikora cyane32-bit ya RISC yibanze ikora kuri 32 MHz yumurongo, ishami ririnda kwibuka (MPU), ibintu byihuta byinjijwemo (kugeza Kbytes 192 za Flash yibuka ya Flash, 6 Kbytes yamakuruEEPROM na 20 Kbytes ya RAM) hiyongereyeho intera nini yo kuzamura I / Os naperiferiya.
Ibikoresho bya STM32L072xx bitanga imbaraga zingirakamaro kubikorwa byinshi.
Byagerwaho hamwe nuguhitamo kwinshi kwimbere ninyuma yisoko yisoko, voltage yimbereguhuza n'imihindagurikire y'ikirere.
Ibikoresho bya STM32L072xx bitanga ibintu byinshi bisa, kimwe 12-bit ADC hamwe nibikoreshokurenza urugero, DAC ebyiri, ebyiri ultra-nke-igereranya-imbaraga, ibihe byinshi, imwe-mbaraga nkeingengabihe (LPTIM), bine rusange-intego 16-biti na bibiri byibanze, imwe RTC nimweSysTick ishobora gukoreshwa nkigihe cyagenwe. Bagaragaza kandi indorerezi ebyiri, izamu rimwehamwe nisaha yigenga nubushobozi bwidirishya hamwe nidirishya rimwe rishingiye kuri busisaha.
Byongeye kandi, ibikoresho bya STM32L072xx byashyizwemo itumanaho risanzwe kandi ryateye imbereImigaragarire: kugeza kuri I2Cs eshatu, SPI ebyiri, I2S imwe, USART enye, UART ifite imbaraga nke(LPUART), hamwe na kristu-idafite USB. Ibikoresho bitanga imiyoboro igera kuri 24Kuri Ongeraho Gusa Gukoraho Gukora Imikorere Kuri Porogaramu.
STM32L072xx nayo ikubiyemo isaha-nyayo hamwe na rejisitiri yo gusubira inyuma isigayeikoreshwa muburyo bwa standby.
Ibikoresho bya ultra-low-power STM32L072xx ikora kuva 1.8 kugeza 3.6 V itanga amashanyarazi (hasi)kugeza kuri 1.65 V kumashanyarazi) hamwe na BOR no kuva kuri 1.65 kugeza 3.6 V amashanyarazi adafite BORihitamo. Baraboneka muri -40 kugeza kuri +125 ° C. Urutonde rwuzuye rwauburyo bwo kuzigama imbaraga butuma igishushanyo cya porogaramu nkeya.
