♠ Ultra-low-power Arm® Cortex®-M4 32-bit MCU + FPU, 100DMIPS, har zuwa 256KB Flash, 64KB SRAM, analog, audio
Na'urorin STM32L431xx sune ƙananan masu sarrafa ƙananan ƙarfi bisa babban aikin Arm® Cortex®-M4 32-bit RISC core wanda ke aiki a mitar har zuwa 80 MHz.Madaidaicin Cortex-M4 yana fasalta naúrar madaidaicin ruwa (FPU) wanda ke goyan bayan duk umarnin sarrafa bayanai guda ɗaya na Arm® da nau'ikan bayanai.Hakanan yana aiwatar da cikakken saitin umarnin DSP da naúrar kariyar ƙwaƙwalwar ajiya (MPU) wanda ke haɓaka amincin aikace-aikacen.
Na'urorin STM32L431xx sun haɗa manyan abubuwan tunawa masu sauri (Ƙwaƙwalwar Flash har zuwa 256 Kbyte, 64 Kbyte na SRAM), ƙirar ƙwaƙwalwar ƙwaƙwalwar Quad SPI (akwai akan duk fakiti) da babban kewayon haɓaka I/Os da na'urori masu alaƙa da bas ɗin APB guda biyu. , motocin bas guda biyu na AHB da matrix na bas mai 32-bit multi-AHB.
Na'urorin STM32L431xx sun haɗa hanyoyin kariya da yawa don shigar da ƙwaƙwalwar Flash da SRAM: kariyar karantawa, rubuta kariya, kariyar karanta lambar mallakar mallaka da Firewall.
Na'urorin suna ba da ADC mai sauri 12-bit (5 Msps), masu kwatanta guda biyu, amplifier ɗaya mai aiki, tashoshi DAC guda biyu, buffer na ciki, ƙaramin ƙarfi RTC, maƙasudin maƙasudin 32-bit mai ƙidayar lokaci, ɗaya 16-bit. PWM mai ƙidayar lokaci da aka keɓe don sarrafa motar, maƙasudin maƙasudin 16-bit masu ƙidayar lokaci guda huɗu, da masu ƙidayar ƙarancin ƙarfi 16-bit guda biyu.
