STM32L072xx microcontrollers-ka aadka u hooseeya waxay ku daraan awooda isku xirkabaska taxanaha ah ee caalamiga ah (USB 2.0 crystal-less) oo leh waxqabadka sare ee Arm Cortex-M0+32-bit RISC core oo ku shaqeeya inta jeer ee 32 MHz, unugga ilaalinta xusuusta (MPU), xusuusta xawaaraha sare leh (illaa 192 Kbytes ee xusuusta barnaamijka Flash, 6 Kbytes oo xog ahEEPROM iyo 20 Kbytes oo RAM ah) oo lagu daray tiro balaadhan oo I/Os la xoojiyey iyohareeraheeda.
Aaladaha STM32L072xx waxay bixiyaan hufnaan sare oo waxqabad ballaaran leh.
Waxaa lagu gaaraa doorasho weyn oo ah ilo saacad gudaha iyo dibadda ah, koronto gudaha ahla qabsiga iyo dhowr habab oo awood yar.
Qalabka STM32L072xx waxay bixiyaan sifooyin analoog ah oo dhowr ah, hal 12-bit ADC oo leh qalabsi xad dhaaf ah, laba DACs, laba isbarbardhigga tamarta-hoose, dhowr saacadood, hal awood hoosesaacada (LPTIM), afar ujeedo-guud oo 16-bit ah iyo laba saacada aasaasiga ah, hal RTC iyo halSysTick kaas oo loo isticmaali karo waqti goyn ahaan.Waxay sidoo kale ka kooban yihiin laba ilaaliye, hal ilaaliyeoo leh saacad madax-bannaan iyo karti daaqadeed iyo hal ilaaliye daaqadeed oo ku salaysan baskasaacada
Intaa waxaa dheer, aaladaha STM32L072xx waxay ku dhejiyeen isgaarsiin heer sare ah iyo mid horumarsanInterfaces: ilaa saddex I2Cs, laba SPIs, hal I2S, afar USARTs, UART awood yar(LPUART), iyo USB aan crystal-ka lahayn.Aaladuhu waxay bixiyaan ilaa 24 kanaal dareen-qaadis lehsi fudud loogu daro taabasho shaqeynta codsi kasta.
STM32L072xx sidoo kale waxaa ku jira saacada-waqtiga-dhabta ah iyo kaydka diiwaanka ee hadhayku shaqeeya habka heeganka
Aaladaha STM32L072xx aadka u hooseeya waxay ka shaqeeyaan koronto 1.8 ilaa 3.6 V ah (hoos u dhac)ilaa 1.65 V marka korantadu hoos u dhacdo) oo leh BOR laga bilaabo 1.65 ilaa 3.6 V oo koronto ah oo aan lahayn BORdoorasho.Waxay ku jiraan heerkulka -40 ilaa +125 °C.Qayb dhamaystiran oo ahhababka awood-badbaadinta waxay u ogolaataa naqshadaynta codsiyada tamarta yar.
