♠ Ultra-low-power Arm® Cortex®-M4 32-bit MCU + FPU, 100 DMIPS, har zuwa 1 MB Flash, 320 KB SRAM, USB OTG FS, audio, SMPS na waje
Na'urorin STM32L496xx masu sarrafa ƙananan ƙananan ƙarfi ne bisa babban aikin Arm® Cortex®-M4 32-bit RISC core wanda ke aiki a mitar har zuwa 80 MHz. Cortex-M4 core yana fasalta madaidaicin 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 STM32L496xx sun haɗa ƙwaƙwalwar ajiyar sauri (har zuwa 1 Mbyte na ƙwaƙwalwar Flash, 320 Kbyte na SRAM), mai sarrafa ƙwaƙwalwar waje mai sassauƙa (FSMC) don ƙwaƙwalwar ajiyar waje (don na'urori tare da fakiti na 100 fil da ƙari), Quad SPI Flash memories interface (samuwa akan duk fakitin da aka haɗa da manyan fakiti biyu) Motocin APB, bas AHB guda biyu da matrix bas mai 32-bit multi-AHB.
Na'urorin STM32L496xx 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 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).
Bugu da kari, har zuwa tashoshi 24 masu karfin ji suna samuwa. Har ila yau, na'urorin sun haɗa haɗaɗɗen direban LCD 8x40 ko 4x44, tare da mai canzawa na ciki.
Har ila yau, sun ƙunshi daidaitattun hanyoyin sadarwa na yau da kullun da ci gaba, wato I2C guda huɗu, SPI uku, USARTs uku, UARTs biyu da UART guda ɗaya Low-Power, SAI biyu, SDMMC ɗaya, CAN guda biyu, USB OTG cikakken sauri, SWPMI ɗaya (Mai sarrafa ka'idar waya guda ɗaya), ƙirar kyamara da mai sarrafa DMA2D.
STM32L496xx yana aiki a cikin -40 zuwa +85 °C (+105 °C junction), -40 zuwa +125 °C (+130 °C junction) zafin jiki ya tashi daga 1.71 zuwa 3.6 V VDD wutar lantarki lokacin amfani da mai sarrafa LDO na ciki da kuma 1.05 zuwa VDD na waje samar da wutar lantarki 1.2SM. Cikakken saitin hanyoyin ceton wutar lantarki yana ba da damar ƙirar aikace-aikacen ƙarancin ƙarfi.
Ana tallafawa wasu kayan wutar lantarki masu zaman kansu: shigarwar samar da wutar lantarki mai zaman kanta na analog don ADC, DAC, OPAMPs da masu kwatancen, 3.3 V ƙaddamar da shigarwar kayan aiki don USB kuma har zuwa 14 I/Os ana iya ba da su da kansu zuwa 1.08 V. Shigar da VBAT yana ba da damar yin ajiyar RTC da rijistar ajiya. Ana iya amfani da keɓantaccen kayan wuta na VDD12 don ƙetare mai sarrafa LDO na ciki lokacin da aka haɗa su zuwa SMPS na waje.
Iyalin STM32L496xx suna ba da fakiti bakwai daga fakitin 64-pin zuwa fakiti 169-pin.
