♠ Arm® Cortex®-M4 32-bit MCU+FPU, 100DMIPS, ilaa 256KB Flash, 64KB SRAM, analoog, maqal

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.

Aaladaha STM32L431xx waxay gundhig u yihiin xusuusta xawliga sare leh (Xusuusta Flash ilaa 256 Kbyte, 64 Kbyte ee SRAM), Quad SPI flash memories interface (oo laga heli karo dhammaan xirmooyinka) iyo I/Os aad u ballaaran oo la xoojiyay iyo qalabyo ku xiran laba bas oo APB ah. , laba bas AHB iyo 32-bit multi-AHB baska.

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 xawaare 12-bit ADC ah (5 Msps), laba isbarbardhig, hal cod-weyneeye, laba kanaal DAC, kayd tixraaca korantada gudaha, awood yar RTC, hal ujeedo guud oo 32-bit ah, hal 16-bit Saacadaha PWM ee u heellan kontoroolka mootada, afar ujeedo-guud oo 16-bit ah, iyo laba waqti-yar oo 16-bit ah.
