Sharaxaada
Aaladaha STM32L422xx waa kontorooleyaasha tamarta-hoose ee 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 STM32L422xx waxay gundhig u yihiin xusuusta xawliga sare leh (Xusuusta Flash ilaa 128 Kbyte,40 Kbyte ee SRAM), Quad SPI flash memories interface (oo laga heli karo dhammaan baakadaha) iyo I/Os ballaaran oo la xoojiyay iyo qalabyo ku xiran laba bas oo APB ah. , laba bas AHB iyo 32-bit multi-AHB baska.Aaladaha STM32L422xx waxay soo dhex galiyeen dhowr habab ilaalin oo loogu talagalay xusuusta Flash iyo SRAM: ilaalinta akhrinta, ilaalinta qorista, ilaalinta koodhka akhrinta lahaanshaha iyo Firewall.Aaladuhu waxay bixiyaan laba 12-bit ADC oo degdeg ah (5 Msps), laba isbarbardhig, hal cod-weyneeye, RTC awood yar, hal ujeedo guud oo 32-bit ah, hal saacad PWM 16-bit ah oo u heellan xakamaynta mootada, afar guud- Ujeedada saacadaha 16-bit, iyo laba wakhti yar oo 16-bit ah.
