♠ 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-power-power-power ishingiye cyane kuri Arm® Cortex®-M4 32-bit ya RISC yibanze ikora kuri frequence igera kuri 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 periferique zahujwe na bisi ebyiri za APB, bisi ebyiri za AHB na materique ya 32-biti ya 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 byihuta 12-biti ADC (5 Msps), ibigereranya bibiri, amplifier imwe ikora, imiyoboro ibiri ya DAC, ibyuma byerekana ingufu za interineti imbere, ingufu nke za RTC, intego rusange ya 32-bit, igihe kimwe cya 16-biti ya PWM yagenewe kugenzura ibinyabiziga, bine rusange-bigamije 16-biti, na bibiri-16-bito-bito.
