♠ aadka u hooseeya ee Arm® Cortex®-M4 32-bit MCU+FPU, 100DMIPS, ilaa 128KB Flash, 40KB SRAM, analoog, ext. SMPS
Aaladaha STM32L412xx 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 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 STM32L412xx waxay ku dhejiyeen xusuusta xawaaraha 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 APB ah, laba AHB2-bus ah.
Aaladaha STM32L412xx waxay gundhigeen dhowr habab ilaalin oo loogu talagalay xusuusta Flash iyo SRAM: ilaalinta akhrinta, ilaalinta qorista, ilaalinta koodhka akhrinta lahaanshaha iyo Firewall.
Aaladu 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 go'ay kontoroolka mootada, afar-ujeedada guud ee 16-bit, iyo laba 16-bit waqti-xoog hooseeya.
Intaa waxaa dheer, ilaa 12 kanaal dareenka awoodda ayaa diyaar ah.
Waxa kale oo ay ka kooban yihiin is-gaarsiinta isgaadhsiinta caadiga ah iyo kuwa horumarsan, kuwaas oo kala ah saddex I2Cs, laba SPIs, saddex USARTs iyo hal awood-hooseeya UART, hal USB-xawaaraha buuxa ee qalabka crystal ka yar.
STM32L412xx wuxuu ka 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 VDD koronto marka la isticmaalayo nidaamiyaha LDO gudaha iyo 1.00 VDD ilaa 1.2PS dibadda ah. Hababka awood-badbaadinta oo dhamaystiran ayaa suurtogal ka dhigaya naqshadaynta codsiyada tamarta yar.
Qaar ka mid ah sahay koronto oo madax banaan ayaa la taageeraa: gelinta sahayda madaxbannaan ee analoogga ee ADC, 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 STM32L412xx waxay bixiyaan lix baakadood oo ka socda 32 ilaa 64-pin.
