I-ultra-low-power STM32L072xx microcontrollers ihlanganisa amandla okuxhumanai-universal serial bus (USB 2.0 crystal-less) ene-Arm Cortex-M0+ esebenza kahle kakhuluI-32-bit RISC core esebenza ngefrikhwensi engu-32 MHz, iyunithi yokuvikela inkumbulo (MPU), izinkumbulo ezishumekwe ngesivinini esikhulu (kufika ku-192 Kbytes wenkumbulo yohlelo lwe-Flash, ama-Kbytes angu-6 wedathaI-EEPROM kanye nama-Kbytes angu-20 we-RAM) kanye nohlu olubanzi lwama-I/O athuthukisiwe kanyeama-peripherals.
Amadivayisi we-STM32L072xx ahlinzeka ngamandla aphezulu ekusebenzeni okubanzi.
Kufezwa ngokukhetha okukhulu kwemithombo yewashi yangaphakathi nangaphandle, i-voltage yangaphakathiukuzivumelanisa nezimo kanye nezindlela ezimbalwa zamandla aphansi.
Amadivayisi we-STM32L072xx anikeza izici ezimbalwa ze-analog, i-12-bit ADC eyodwa ene-hardware.amasampula amaningi, ama-DAC amabili, izifanisi ezimbili zamandla aphansi kakhulu, izibali sikhathi ezimbalwa, amandla aphansi owodwatimer (LPTIM), izibali-sikhathi ezine zenjongo evamile engu-16-bit kanye nesibali sikhathi esiyisisekelo esibili, i-RTC eyodwa neyodwaSysTick engasetshenziswa njengezisekelo zesikhathi. Baphinde bafake nezinja ezimbili, inja eyodwa yokubukangewashi elizimele kanye nekhono lewindi kanye ne-watchdog eyodwa yewindi esekelwe ebhasiniiwashi.
Ngaphezu kwalokho, amadivayisi we-STM32L072xx ashumeka ukuxhumana okujwayelekile nokuthuthukileukuxhumana: kufika kuma-I2C amathathu, ama-SPI amabili, i-I2S eyodwa, ama-USART amane, i-UART enamandla aphansi(LPUART), kanye ne-USB engena-crystal. Amadivayisi anikela ngamashaneli enzwa angama-24ukumane wengeze ukusebenza kwenzwa yokuthinta kunoma yiluphi uhlelo lokusebenza.
I-STM32L072xx ifaka newashi lesikhathi sangempela kanye nesethi yamarejista ayisipele asele.inikwe amandla kumodi yokulinda.
Amadivayisi anamandla aphansi kakhulu e-STM32L072xx asebenza kusuka ku-1.8 kuya ku-3.6 V kagesi (phansiukuya ku-1.65 V ngamandla aphansi) nge-BOR futhi kusukela ku-1.65 kuya ku-3.6 V kagesi ngaphandle kwe-BORinketho.
