♠ Ultra-power-power Arm® Cortex®-M4 32-bit MCU + FPU, 100DMIPS, igera kuri Flash ya 256KB, 64KB SRAM, igereranya, amajwi
Ibikoresho bya STM32L431xx ni microcontrollers ya ultra-low-power-power ishingiye cyane kuri Arm® Cortex®-M4 32-bit ya RISC yibanze ikora kuri frequence ya 80 MHz.Cortex-M4 yibanze iranga Floating point unit (FPU) icyerekezo kimwe gishyigikira Arm® imwe-imwe-yamakuru-yo gutunganya amakuru hamwe nubwoko bwamakuru.Irashyira mubikorwa kandi byuzuye amabwiriza ya DSP hamwe nigice cyo kurinda kwibuka (MPU) byongera umutekano wibisabwa.
Ibikoresho bya STM32L431xx byashyizwemo kwibuka byihuse (Flash yibuka igera kuri 256 Kbyte, 64 Kbyte ya SRAM), interineti yibuka ya Quad SPI (iboneka kumapaki yose) hamwe nurwego runini rwa I / Os hamwe na periferiya ihuza bisi ebyiri za APB. , bisi ebyiri za AHB hamwe na materix ya 32-biti-AHB.
Ibikoresho bya STM32L431xx byashyizwemo uburyo bwinshi bwo kurinda ibikoresho bya Flash yibitseho na SRAM: kurinda gusoma, kwandika kurinda, kurinda kode yihariye hamwe na Firewall.
Ibikoresho bitanga ADC yihuta 12-biti (5 Msps), igereranya ebyiri, amplifier imwe ikora, imiyoboro ibiri ya DAC, ibyuma byerekana ingufu za voltage imbere, ingufu nke za RTC, intego rusange-32-biti, imwe 16-bit Igihe cya PWM cyeguriwe kugenzura moteri, bine rusange-intego-16-biti, na bibiri-16-bito-by-imbaraga.
Mubyongeyeho, imiyoboro igera kuri 21 ya capacitive sensing irahari.
