Sharaxaada
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 of SRAM), Quad SPI flash memories interface (oo laga heli karo dhammaan baakadaha) 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 12-bit ADC (5 Msps), laba is barbardhigiyaal, hal cod-weyneeye, laba kanaal DAC, kayd tixraac korantada gudaha ah, awood yar oo RTC ah, hal ujeedo guud 32-bit timer, hal saacad PWM 16-bit ah. u heellan xakamaynta mootada, afar ujeedo-guud ah oo 16-bit ah, iyo laba wakhti-yar oo 16-bit ah.Intaa waxaa dheer, ilaa 21 kanaal dareenka awoodda leh ayaa diyaar ah.Waxa kale oo ay ka muuqdaan isgaadhsiinta isgaadhsiinta caadiga ah iyo kuwa horumarsan.Saddex I2Cs • Saddex SPIs • Saddex USARTs iyo hal UART oo awood-hoose ah.Hal SAI (Serial Audio Interfaces) • Hal SDMMC • Hal CAN • Hal SWPMI (Single Wire Protocol Master Interface) STM32L431xx wuxuu ka shaqeeyaa -40 ilaa +85 °C (+105 °C isgoyska), -40 ilaa +105 ° C (+125 °C isgoyska) iyo -40 ilaa +125 °C (+130 °C isgoyska) heerkulku wuxuu u dhexeeyaa 1.71 ilaa 3.6 V.Hababka awood-badbaadinta oo dhammaystiran ayaa u oggolaanaya naqshadaynta codsiyada tamarta hooseeya.Qaar ka mid ah sahayda korantada ee madaxa banaan ayaa la taageeray: gelinta sahayda madaxbannaan ee analoogga ee ADC, DAC, OPAMP iyo isbarbardhigga.Soo gelinta VBAT waxay ogolaataa in lagu kaydiyo diiwaanka RTC iyo kaydinta.Qoyska STM32L431xx waxay bixiyaan sagaal xirmo oo ka socda 32 ilaa 100-pin xirmo.
