♠ aadka u hooseeya ee Arm® Cortex®-M4 32-bit MCU+FPU, 100DMIPS, ilaa 512KB Flash, 160KB SRAM, analoog, maqal
Aaladaha STM32L451xx waa kontaroolayaal yar-yar oo awood yar ah oo 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 halbeeg saxan oo sabbaynaysa unug (FPU) taas oo taageerta dhammaan tilmaamaha habaynta xogta saxda ah ee Arm® 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.
Qalabka STM32L451xx waxay ku dhejiyeen xusuusta xawaaraha sare leh (Xusuusta Flash ilaa 512 Kbyte, 160 Kbyte ee SRAM), Quad SPI Flash memories interface (oo laga heli karo dhammaan baakadaha) iyo noocyo badan oo I / Os ah oo la xoojiyay iyo qalabyo ku xiran laba bas APB ah, laba AH3B-buses ah
Aaladaha STM32L451xx 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 12-bit ADC (5 Msps), laba isbarbardhig, hal cod-weyneeye, hal kanaal DAC, kayd tixraaca korantada gudaha, awood hoose RTC, hal ujeedo guud oo 32-bit ah, hal saacad PWM 16-bit ah oo u heellan xakamaynta mootada, afar ujeedo-guud ah oo 16-bit ah, iyo laba-wakhti-16-yar.
Intaa waxaa dheer, ilaa 21 kanaal dareenka awoodda leh ayaa diyaar ah.
Waxa kale oo ay ka kooban yihiin is-gaarsiinta isgaadhsiinta caadiga ah iyo kuwa horumarsan, kuwaas oo kala ah afar I2Cs, saddex SPIs, saddex USARTs, hal UART iyo hal UART oo hooseeya, hal SAI, hal SDMMC, hal CAN.
STM32L451xx wuxuu ku shaqeeyaa -40 ilaa +85 °C (+105 °C isgoyska) iyo -40 ilaa +125 °C (+130 °C isgoyska) heerkulku wuxuu u dhexeeyaa 1.71 ilaa 3.6 V. Hababka awood-badbaadinta oo dhamaystiran ayaa suurtogal ka dhigaya naqshadaynta codsiyada tamarta yar.
Qaar ka mid ah sahayda korantada ee madaxa banaan ayaa la taageeray: gelinta sahayda madaxbannaan ee analoogga ee ADC, DAC, OPAMP iyo isbarbardhigga. Wax gelinta VBAT waxay suurtogal ka dhigaysaa in la kaydiyo RTC iyo diiwaannada kaydinta.
Qoyska STM32L451xx waxay bixiyaan lix xirmo oo ka socda 48 ilaa 100-pin xirmo.
