Sharaxaada
Aaladaha STM32L471xx waa kontaroolayaasha yar-yar ee awoodda aadka u hooseeya ee ku saleysan 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 STM32L471xx waxay ku duugan yihiin xusuusta xawliga sare leh (Xusuusta Flash ilaa 1 Mbyte, ilaa 128 Kbyte ee SRAM), kontaroolaha xusuusta debedda ee dabacsan (FSMC) ee xusuusta taagan (qalabka wata baakadaha 100 biin iyo ka badan), Quad SPI Flash memories interface (oo laga heli karo dhammaan xirmooyinka) iyo I/Os aad u ballaaran oo la xoojiyey iyo qalabyada ku xiran laba bas oo APB ah, laba bas AHB iyo 32-bit multi-AHB matrix.Aaladaha STM32L471xx waxay gundhigeen dhowr habab ilaalin oo loogu talagalay xusuusta Flash iyo SRAM: ilaalinta akhrinta, ilaalinta qorista, ilaalinta koodhka akhrinta lahaanshaha iyo Firewall.Aaladuhu waxay bixiyaan ilaa saddex xawli ah oo 12-bit ADCs ah (5 Msps), laba isbarbardhig, laba amplifiers hawlgalka, laba kanaal DAC, kayd tixraac danab gudaha ah, awood yar oo RTC ah, laba ujeedo guud oo 32-bit ah, laba 16 Saacadaha PWM-bit ee u heellan xakamaynta mootada, toddobo waqti-ujeedo-guud ah oo 16-bit ah, iyo laba wakhti-yar oo 16-bit ah.Aaladuhu waxay taageeraan afar filtarrada dhijitaalka ah ee modulators sigma delta dibadda (DFSDM).
