Sharaxaada
Aaladaha STM32L452xx waa kontorooleyaasha 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® hab-raaca 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 STM32L452xx waxa ay galiyeen xasuus xawli sare leh (Xusuusta Flash ilaa 512 Kbyte, 160 Kbyte ee 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 STM32L452xx 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 12-bit ADC (5 Msps), laba isbarbardhig, hal cod-weyneeye, hal kanaal DAC, bakhaar tixraac 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 kooban yihiin is-gaarsiinta isgaadhsiinta caadiga ah iyo kuwa horumarsan, kuwaas oo kala ah afar I2Cs, saddex SPIs, saddex USARTs, hal UART iyo hal awood-hooseeya UART, hal SAI, hal SDMMC, hal CAN, hal USB-xawaaraha buuxa ee qalabka crystal ka yar.STM32L452xx waxay ku shaqeysaa -40 ilaa +85 °C (+105 °C isgoyska) iyo -40 ilaa +125 °C (+130 °C isgoyska) heerkulku wuxuu u dhexeeyaa 1.71 ilaa 3.6 VD korantada marka la isticmaalayo maamulaha LDO gudaha. iyo 1.05 ilaa 1.32V VDD12 koronto marka la isticmaalayo sahayda SMPS ee dibadda ah.Hababka awood-badbaadinta oo dhamaystiran ayaa suurtogal ka dhigaya naqshadaynta codsiyada tamarta hoose.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.Sahayda korantada ee VDD12 ee go'an ayaa loo isticmaali karaa in laga gudbo maamulaha LDO gudaha marka lagu xiro SMPS dibadda ah.Qoyska STM32L452xx waxay bixiyaan todobo xirmo laga bilaabo 48 ilaa 100-pin xirmo.
