Sharaxaada
Qalabka aadka u hooseeya ee STM32L073xx microcontrollers waxay ku daraan awooda isku xirka baska taxanaha 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, unug ilaalinta xusuusta ( MPU), xusuusta xawaaraha sare leh (ilaa 192 Kbytes ee xusuusta barnaamijka Flash, 6 Kbytes ee xogta EEPROM iyo 20 Kbytes ee RAM) oo ay weheliso tiro balaadhan oo I/Os ah oo la xoojiyey.Aaladaha STM32L073xx waxay bixiyaan hufnaan sare oo waxqabad ballaaran leh.Waxaa lagu gaaraa doorasho weyn oo ah ilo saacad gudaha iyo dibadda ah, la qabsiga korantada gudaha iyo dhowr nooc oo awood hooseeya.Aaladaha STM32L073xx waxay bixiyaan sifooyin analoog ah oo dhowr ah, hal 12-bit ADC oo leh qalab xad dhaaf ah, laba DACs, laba isbarbardhig-hooseeya, dhowr waqti, hal saacad awood yar (LPTIM), afar ujeedo-guud oo 16-bit ah iyo laba saacada aasaasiga ah, hal RTC iyo hal SysTick kaas oo loo isticmaali karo wakhti go'an.Waxa kale oo ay ka kooban yihiin laba ilaaliye, hal ilaaliye leh saacad madax-bannaan iyo karti dariishadaha iyo hal ilaaliye daaqadeed oo ku salaysan saacadda baska.Intaa waxaa dheer, aaladaha STM32L073xx waxay ku dhejiyeen is-gaarsiinta caadiga ah iyo kuwa horumarsan: ilaa saddex I2Cs, laba SPIs, hal I2S, afar USARTs, UART awood yar (LPUART), iyo USB-ka-yar.Aaladuhu waxay soo bandhigaan ilaa 24 kanaal dareenka awoodda leh si ay si fudud ugu daraan waxqabadka dareenka taabashada codsi kasta.STM32L073xx sidoo kale waxaa ku jira saacada-waqtiga-dhabta ah iyo kayd kayd ah oo ku sii shaqaynaya qaabka heeganka.Ugu dambeyntii, kontaroolayaashooda LCD ee isku dhafan waxay leeyihiin koronto-dhaliye LCD ah oo ku dhex-yaalla kaasoo u oggolaanaya inuu wado ilaa 8 LCD-ka-badan oo kala duwan oo ka madax-bannaan korantada saadka.Qalabka STM32L073xx ee aadka u hooseeya waxay ka shaqeeyaan sahay koronto oo ah 1.8 ilaa 3.6 V (hoos ilaa 1.65 V marka korantada hoos loo dhigo) oo leh BOR iyo min 1.65 ilaa 3.6 V oo koronto ah iyada oo aan lahayn ikhtiyaar BOR.Waxay ku jiraan heerkulka -40 ilaa +125 °C.Qaab-dhismeed dhammaystiran oo ah hababka kaydinta awoodda ayaa u oggolaanaya naqshadeynta codsiyada tamarta yar.
