Inkcazo
I-Ultra-low-low-power STM32L073xx microcontrollers idibanisa amandla okudibanisa ibhasi ye-serial yendalo yonke (i-USB 2.0 crystal-less) ene-high-performance Arm Cortex-M0 + 32-bit RISC core esebenza kwi-32 MHz rhoqo, iyunithi yokukhusela imemori ( I-MPU), iinkumbulo ezizinziswe ngesantya esiphezulu (ukuya kwi-192 Kbytes yememori yenkqubo yeFlash, i-6 Kbytes yedatha ye-EEPROM kunye ne-20 Kbytes ye-RAM) kunye noluhlu olubanzi lwee-I/Os eziphuculweyo kunye neeperipherals.Izixhobo ze-STM32L073xx zibonelela ngokusebenza kwamandla aphezulu kuluhlu olubanzi lokusebenza.Iphunyezwa ngokhetho olukhulu lwemithombo yewotshi yangaphakathi nangaphandle, ukulungiswa kombane wangaphakathi kunye neendlela ezininzi zamandla aphantsi.Izixhobo ze-STM32L073xx zibonelela ngeempawu ezininzi ze-analog, enye i-12-bit ADC ene-hardware oversampling, ii-DAC ezimbini, izithelekisi zamandla asezantsi kakhulu, izibali-xesha ezininzi, isibali-xesha esine-low-power (LPTIM), isibali-xesha se-16 esinenjongo jikelele kunye nezimbini. isibali-xesha esisisiseko, iRTC enye kunye neSysTick enye enokusetyenziswa njengeziseko zexesha.Zikwabonisa ii-watchdogs ezimbini, i-watchdog enye enewotshi ezimeleyo kunye nekhono lefestile kunye ne-window watchdog enye esekelwe kwiwashi yebhasi.Ngaphezu koko, izixhobo ze-STM32L073xx zifakela unxibelelwano olusemgangathweni kunye nonxibelelwano oluphambili: ukuya kuthi ga kwi-I2Cs ezintathu, ii-SPI ezimbini, i-I2S enye, ii-USART ezine, i-UART enamandla aphantsi (LPUART), kunye ne-USB engaphantsi kwekristale.Izixhobo zibonelela ukuya kuthi ga kwi-24 capacitive sensing channels ukongeza ngokulula ukusebenza kwe-touch sensing kuso nasiphi na isicelo.I-STM32L073xx ikwabandakanya iwotshi yexesha langempela kunye neseti yeerejista zogcino ezihlala zisebenza kwimo yokulinda.Ekugqibeleni, umlawuli wabo we-LCD odibeneyo une-LCD ye-voltage generator eyakhelwe ngaphakathi evumela ukuqhuba ukuya kuthi ga kwi-LCD ephindwe kabini ngokungafaniyo ngaphandle kombane wokubonelela.Izixhobo ze-STM32L073xx ze-ultra-low-power zisebenza ukusuka kwi-1.8 ukuya kwi-3.6 V ukunikezelwa kwamandla (ukuhla ukuya kwi-1.65 V kumandla aphantsi) kunye ne-BOR kunye ne-1.65 ukuya kwi-3.6 V unikezelo lwamandla ngaphandle kwe-BOR inketho.Zifumaneka kwi -40 ukuya +125 °C kuluhlu lobushushu.Iseti ebanzi yeendlela zokugcina amandla ivumela ukuyilwa kwezicelo zamandla aphantsi.
