♠ Ultra-low-power Arm® Cortex®-M4 32-bit MCU+FPU, 100DMIPS, har zuwa 1MB Flash, 128 KB SRAM, USB OTG FS, LCD, ext. SMPS
Na'urorin STM32L476xx 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 STM32L476xx sun haɗa ƙwaƙwalwar ajiyar sauri (Ƙwaƙwalwar Flash har zuwa 1 Mbyte, har zuwa 128 Kbyte na SRAM), mai sarrafa ƙwaƙwalwar waje mai sassauƙa (FSMC) don ƙwaƙwalwar ajiya (don na'urori tare da fakiti na 100 fil da ƙari), Quad SPI ƙwaƙwalwar ƙwaƙwalwar ajiyar ƙwaƙwalwar ajiya (samuwa akan duk fakitin da aka haɗa) da fakitin I. Motocin APB, bas AHB guda biyu da matrix bas mai 32-bit multi-AHB.
Na'urorin STM32L476xx sun haɗa hanyoyin kariya da yawa don shigar da ƙwaƙwalwar Flash da SRAM: kariyar karantawa, rubuta kariya, kariyar karanta bayanan mallakar mallaka da Firewall.
Na'urorin suna ba da har zuwa 12-bit ADCs masu sauri guda uku (5 Msps), masu kwatanta biyu, amplifiers guda biyu, tashoshin DAC guda biyu, ƙarancin wutar lantarki na ciki, ƙarancin wutar lantarki RTC, maƙasudin maƙasudin 32-bit mai ƙidayar lokaci guda biyu, masu ƙidayar 16-bit PWM guda biyu waɗanda aka keɓe don sarrafa motar, maƙasudin maƙasudin 16-bit 16 masu lokaci guda biyu. Na'urorin suna tallafawa matatun dijital guda huɗu don masu daidaita sigma delta na waje (DFSDM).
