Sharaxaada
Aaladaha STM32L552xx waa qoys kontaroolayaal yar-yar oo awood yar leh (STM32L5 Series) oo ku salaysan waxqabadka sare ee Arm® Cortex®-M33 32-bit RISC core.Waxay ku shaqeeyaan inta jeer ee ilaa 110 MHz.Xudunta Cortex®-M33 waxa ay leedahay halbeeg sax ah oo sabbaynaysa-dhibcaha (FPU), kaas oo taageera dhammaan tilmaamaha habaynta xogta saxda ah ee Arm® iyo dhammaan noocyada xogta.Xudunta Cortex®-M33 waxa kale oo ay fulisaa hab dhammaystiran oo ah DSP (habaynta calaamadaha dhijitaalka ah) tilmaamaha iyo unugga ilaalinta xusuusta (MPU) kaas oo kor u qaadaya amniga codsiga.Aaladahani waxay ku jiraan xusuusta xawaaraha sare leh (512 Kbytes of Flash memory iyo 256 Kbytes of SRAM), kontaroolaha xusuusta debedda ee dabacsan (FSMC) ee xusuusta taagan (qalabka wata baakadaha 100 biin iyo ka badan), Octo-SPI Flash memories interface. (waxaa laga heli karaa dhammaan baakadaha) iyo I/Os aad u ballaaran oo la xoojiyey iyo qalabyo ku xiran laba bas APB, laba bas AHB iyo 32-bit multi-AHB matrix baska.Aaladaha Taxanaha STM32L5 waxay bixiyaan aasaas amni oo waafaqsan shuruudaha qaab dhismeedka amniga ku saleysan ee la aaminsan yahay (TBSA).Waxay cuskadeen astaamaha amniga lagama maarmaanka u ah si ay u hirgeliyaan boot sugan, kaydinta xogta sugan, rakibaadda firmware aamin ah iyo casriyeyn aamin ah.Wareegga nolosha dabacsan ayaa la maareeyaa iyada oo ay ugu wacan tahay heerar badan oo ilaalinta akhrinta.Go'doominta qalabka firmware-ka waxaa la taageeray iyada oo ay ugu wacan tahay meelaha la sugi karo, xusuusta iyo I/Os, iyo sidoo kale suurtagalnimada in meelaha durugsan iyo xusuusta loo habeeyo "mudnaan".Aaladaha STM32L552xx waxa ay geliyeen dhowr habab ilaalin oo loogu talagalay xusuusta Flash iyo SRAM: ilaalinta akhrinta, ilaalinta qorista, meelaha ilaalinta ammaansan iyo qarsoon.
