Aaladaha STM32L431xx waa kontaroolayaasha yar-yar ee awoodda aadka u hooseeya ee ku salaysan waxqabadka sare ee Arm® Cortex®-M4 32-bit RISC core oo ku shaqeeya soo noqnoqda ilaa 80 MHz. Xudunta Cortex-M4 waxa ay leedahay unug dhibicda sabbaynaysa (FPU) oo hal sax ah oo taageerta dhammaan Arm® habraaca habaynta xogta saxda ah iyo noocyada xogta. Waxa kale oo ay fulisaa habraac buuxa oo ah tilmaamaha DSP iyo unugga ilaalinta xusuusta (MPU) kaas oo kor u qaadaya amniga codsiga.
Qalabka STM32L431xx waxay ku dhejiyeen xusuusta xawaaraha sare leh (Xusuusta Flash ilaa 256 Kbyte, 64 Kbyte ee SRAM), Quad SPI flash memories interface (oo laga heli karo dhammaan baakadaha) iyo baaxad ballaaran oo I / Os ah oo la xoojiyay iyo qalabyo ku xiran laba bas oo APB ah, laba AHB-buses ah.
Aaladaha STM32L431xx waxay gundhig u yihiin dhowr habab ilaalin oo loogu talagalay xusuusta Flash iyo SRAM: ilaalinta akhrinta, ilaalinta qorista, ilaalinta koodhka akhrinta lahaanshaha iyo Firewall.
Aaladuhu waxay bixiyaan 12-bit ADC (5 Msps), laba isbarbardhig, hal cod-weyneeye, laba kanaal DAC, bakhaar tixraaca korantada gudaha ah, awood yar oo RTC ah, hal ujeedo guud oo 32-bit ah, hal saacad PWM 16-bit ah oo u go'ay xakamaynta mootada, afar ujeedo guud 16-bit timers-, iyo laba wakhti yar 1.
Intaa waxaa dheer, ilaa 21 kanaal dareenka awoodda leh ayaa diyaar ah.
